• Queries on techniques of management of memory in VMware

  Hello

  A query on techniques of management of memory in VMware:

  Suppose that my ESX 4.1 server runs on a host having 8 GB of RAM. Now I create five virtual machines with Windows 2003 guest OS and specify a reserve of memory of 1 GB. In this case, assume that I turn on all five VMs sequentially VM1 to VM5. Assume VM4 and VM5 are inactive (no activity inside the BONE invited) and VM1, VM2, VM3 run under maximum loads. In this case the VMKernel dynamically allocate the memory of VM4 VM5 of other three virtual machines running?

  I guess the real issue here is booking: 1 GB memory must be free on the host to start a virtual machine in this case. However if the guest OS is not heavily loaded would be the VMKernel still swap pages of memory to the VM slowed using memory management techniques ESX?

  Thanks, Vivek

  Yes - is VM4 VM5 do not use the full reservation of memory 1 GB memory will be available to other virtual machines - once these virtual machines started memory bemanding memory will be recovered and given to those virtual machines

  I guess the real issue here is booking: 1 GB memory must be free on the host to start a virtual machine in this case. However if the guest OS is not heavily loaded would be the VMKernel still swap pages of memory to the VM slowed using memory management techniques ESX?

  Yes - even if the virtual machine is not under heavy load, but other VMS are it will swap memory for the by the VM vmkernel swap file

• Design of network for VMware/iSCSI SAN

  I am currently reshaping our business network to take account of the variation between stand-alone servers and an Equallogic/VMware environment. We will use iSCSI to connect to the virtual machine to the San.

  My question is this. How a proper network design should seek this kind of deployment? I've specified my current hardware less than what I have to work with. Given that I can't pay by port / vlan database MTU value on the 3750/2960 should I dedicate a switch for iSCSI?

  Equipment available:

  Core switch/router:

  WS-C37560G-24TS-1U

  Stacked switches:

  WS-C2960S-48TS-L access switch

  WS-C2960S-48TS-L access switch

  WS-C2960S-48LPS-L voice changer

  WS-C2960S-24TS-L Server switch (dedicated iSCSI Possible)

  Unused stacked switches:

  Dell Powerconnect 6224 x 2 reference

  Servers:

  Reference Dell R710 Quad NIC

  Reference Dell R610 Quad NIC

  Storage:

  EqualLogic PS4100 with two 2 x 1 GbE controllers = 4 GbE for iSCSI

  Best regards

  Markus

  given that the same logic has two controllers that you will have to use a pair of switches to cross connect for redundancy. You are going to need some maps as well. 1 sc, 1 for vmotion, 2 for iscsi (cross connected) and probably 2 for the production traffic.

• Update Windows 10 November (10586 aka 1511): bcdedit/set hypervisorlaunchtype off, but VMware Workstation does not start VMs with conflict of Hyper-V

  Hi all

  I upgraded from Windows 10 Windows 10 November updated this morning.

  I have the Hyper-V role is installed and use it from time to time, but bcdedit to configure the boot loader to disable Hyper-V by hypervisorlaunchtype power off.

  This technique has worked with 10 Windows and VMware Workstation and I could start and run virtual machines

  Since I did the upgrade, I can't start VM with this standard message "VMware Workstation and Hyper-V are not compatible"

  I am running VMware Workstation 10, but suspect that this problem also exists with later versions.

  Everyone knows about this problem?

  Someone at - he found a solution?

  I'm willing to fork over $150 for 12 workstations to solve this problem, but I want to know with certainty that it is circumventing my problem.

  Thanks for that.

  Uninstallation and reinstallation of the hyper-v feature, following the upgrade of Windows Windows 10 November 10 update solved the problem.

  I still need to run the following command to disable the Hyper-V technology

  bcdedit/set hypervisorlaunchtype

  Thanks to everyone for their help.

• new to vmware, vsphere and networking vswitch

  Hi all

  I am new to virtualization, but decided to try it since my company is going full on ESXI5.5.  That is why I hope that some kind gurus here can point me in the right direction regarding some doubts I have... and do not forgive me if I ask ridiculous questions...

  ==========

  So far, I know that VMs, through their vNIC connect to vSwitch which is in turn connected to the physical machine or the host ESXI (vmnic) network card. The vmnic is then connected to a real L2/L3 switch.

  [VM Vnic] <>- [vswitch] <>- [vmnic] <>- [physical switch]

  However, what I don't understand is how the vmnic actually works to spread the traffic "inward" to the vswitch? I can't really come up with one question to explain my doubt, but below are the doubts that I asked myself->

  • How is he able to assign the IP off the internal virtual machines?
  • When an outer package of the physical switch is being sent to the vmnic how he spend in-house for internal virtual computers?
  • How even knows designated IP belong to a virtual machine inside and "inward" to happen to the vswitch?
  • Is the vmnic using address IP or MAC to decide if it means putting the package inside the switch?
  • When an arp request for a virtual machine IP is send from the outside, the vmnic will reply with its mac address?
  • When an arp request is sent from an internal virtual machine, the vmnic keep track of the mac address of the virtual machine so that next time, when he saw a response to this MAC, he knows inside 'before' the vSwitch
  • What is this work something like a 'bridge' mode fill the vswitch internal to the external physical switch? Is there a table of addresses belonging to the vmnic mac?
  • Whenever the IP of the virtual computer is assigned, the IP address will be "bind" to the vmnic?
  • How register us all IP or Mac addresses (if any) that are associated with a vmnic?

  Or rather simply, I wonder how the physical network adapter on the host (esxi), knows that he must transfer a frame "inward" to the vswitch? is there a link OF the virtual machine to the interface? or nic was a table of addresses mac or something... (but the mac address table guess belong to vswitch?)

  Thank you.

  Kind regards

  Hello

  Welcome to the community!

  I would like to start with a doc. I recommend you to read our VMware Virtual Networking Concepts guide that I hope will help you to better understand the basic details of the virtual in VMware switch, even if it's a bit old.

  On your last question, however:

  > Or rather simply put, I wonder how the physical network adapter on the host (esxi), knows that he must transfer a frame "inward" to the vswitch? is there an IP link from the virtual machine to the interface? or nic was a table of addresses mac or something... (but the mac address table supposed to belong to vswitch?)

  The vminc (i.e. the physical card) on the ESXi host is not that there is a virtual switch behind it. It transfers the packets to the driver and then the top layer software it management. There is no magic to this topic. In some cases, there are a few added techniques (for example netqueue), but the basis remains the same. Vmnic (i.e. the physical NETWORK adapter card) does not keep the information of MAC address of the virtual machine on virtual machines, but does the vSwitch. But even the vSwitch does not retain details of the IP address.

  A virtual switch, as such, doesn't have the same kind of as a physical switch mac address table. If a virtual machine under tension then the vSwitch stores the virtual port <->combination MAC address number and keeps it like that (so far it's really no different a physical switch). A big difference is that, well that the vSwitch does not learn the MAC addresses of the external network. If there is a picture of outside with the MAC address of unicast for which there is no port isn't linked then the packet gets dropped. And if the virtual machine sends traffic to another MAC that does not exist in the virtual switch and then it will be sent out via the uplink (s) (if it exists).

  The MAC address of the vmnic does not play here (unless one of the vmkernel interface pulls his MAC to an adapter of uplink).

  I hope this helps. Let me know if you still have any questions.

• T of what guest operating systems will start the VMware Support for EFI?

  Is there a list of support guest OS for the EFI firmware?  Mianly supported by VMware - do not try, fail, call support technique etc etc.   My experiences on the TP forums, I guess that there is not.  Some OS (such as Windows Server) come with a screen to choose BIOS/EFI firmware.  If not, you need to go to setting > Hard Drive OPtions-> advanced _ > boot using EFI.  In particular there at - it versions of Linux that you give you option of BIOS/EFI firmware before the confutation of VM is complete, so the hard drive then be custom.

  We will officially support the EFI firmware for any guest operating system to which all the following conditions are met:

  • We list this guest operating system, supported in the VMware Compatibility Guide for operating systems and your virtualization product.
  • The guest operating system supports EFI in the operating system installation media.
  • Support the guest OS EFI has no catastrophic flaws (for example Fedora 12 x 64, FreeBSD 11, Centos 6.0 through all the 6.2 have catastrophic flaws).

  New computer virtual assistant of 11 workstation has only the option of EFI firmware for Windows clients.  Special mention, do not yet support us Easy Install for non EFI customers in 11 workstations.  For all other customer support EFI OSes, you can do a manual installation after choosing the EFI firmware in the virtual machine settings > Options > Advanced > Boot with EFI instead of the BIOS.

  I don't understand your concern about the personalization of the hard drive... Could you elaborate?

  See you soon,.

• Deleting VMware and all that it has associated delete folders/files Mac OS and volume virtual... correct?

  Hello world

  I used the trial of VM for a bit, ran 10.8 Mac on my machine 10.9. I used CleanApp to remove the VMware application and everything that it has combined the files/folders. Wondering if this technique also removes the Mac OS that has been installed on a virtual computer and removes the virtual volume? I think I lost a lot of free space on my SSD.

  Thank you!

  John

  I found this post of disk space missing after uninstalling VMware Fusion 6 and the suggested disk inventory X installed. The app found the Mac OS folder that contains the file 21 GB + virtual Disk.vmdk and the rest. (I totally forgot this file and location when I installed everything first.) Trashed the entire folder and appear to regain space lost to SSD, but I think that there are even more is lost.

  The kind of wave removes the above folder that contains the virtual file Disk.vmdk below article.

• VMware View - provisioning question of desktop computers

  I'm new to VMware View and just build a my QA cluster environment.  I have installed/configured view administrator on a dedicated virtual machine and installed/configured on my server vCenter composer.  I created a gold statue (called, joined the domain, configured custom parameters, view agent installed) and converted to a model. Then, I created a pool on my server administrator to view and added 10 desktop computers.  They have all implemented successfully, however, they all have the same computer name (same name, I named the machine of the gold statue).  The machines that appear in VMware show the naming convention that I created, but the internal computer name is the same for all. I guess that the DNS name.  also, I can have these machines added to the announcement through this process or do they need to be predefined?

  Customization = None seems to be the reason. When we customize him clone all the related machine settings are kept from the model VM, which are the name of the Machine, machine SID, the work/domain group settings, etc. That's why you see Office all the same names as those given to the model. You can create a customization specification in the CR. Instructions to create a file of customiztion specifications in vCenter can be found at:

  http://pubs.vmware.com/vsphere-4-esx-vcenter/index.jsp?topic=/com.vmware.vsphere.vmadmin.doc_41/vsp_vm_guide/deploy_vms_from_templates_and_clones/t_create_a_customization_specification_for_windows.html

  Use this technique of customization when you create the pool. Hope that helps.

• "VMware-KVM" can act as a countermeasure for detectors VM?

  VMware-KVM- Many of our customers have requested a way to run a virtual machine so that their employees or students do not realize they are in a virtual machine!  In this overview, we have included an executable (Windows only for now) coming.  Run vmware - vmx kvm.exe - file.vmx from the command line and your VM will launch in fullscreen with no toolbar or of any other indicator that you are running a virtual machine.

  Hello

  I'm new here and I am interested in this aspect of the TP.

  As far as I know some application will use some techniques to detect whether they are running inside a Virtual Machine.

  So I wonder if this device can be used (or intended to be), as a countermeasure for those detectors VM, or it's just a high level feature that will just enhance the visual experience.

  Thank you!

  BTW: What's new in VMware Workstation July 2013 technology overview

  The VMware Workstation team is pleased to announce the VMware Workstation Technology Preview - release of may 2013!

  It still reads 'may 2013 '. Do you still have this article updated?

  These days, you are unlikely to be using the binary translation.  However, it is relatively easy to detect that you are running in a virtual machine.  One thing you could try is:

  monitor_control.restrict_backdoor = TRUE

  Hypervisor.CPUID.v0 = FALSE

  This will stop the hypervisor to declare at the prompt.

• Why VMware?

  Hey guys,.

  I had a discussion with a brilliant super architect. I continued talking vmware when she is in openstack. He asked me this,

  "Tell me what is the future of the computer company such as VMware." Why a customer would pay for these software expensive while that Openstack and open source will be to provide all the necessary functionality"

  I could come only with care as the answer, but what you really think?

  Thank you

  RJ

  There is not bad... of thinking, understanding... lets talk with a few points

  1 - industry proven... maturity... stability

  of course, the open stack is great... and it has great future... but still, he is yet to prove... and accept. VMware is the pioneer... they founded the perfect and complete recipe for virtualization in the data center... and now it's a perfect cloud OS and there is evidence the industry. and he's mature...

  2 - management...

  Just leave the capacity... or technical... Details... at the end of the day... an organization is managed and maintained by engineers... or admins... and not by the architects... then how easy to train a person... How fast it can adopt the vmware... and how effective is the management of the layer... the capablities automation... that means a lot.

  3 - layer hpervisor... or the virtualization layer

  all other vendors like hyperv... Citrix... kvm... etc... all have need of assistance of the BONE... the VMkernel is a Scheduler task very evolved... lying and coded... and built for one JOB to run VM... so less number of CODE in the software... and less bug and less Vulnerability

  4-company characteristics

  Everyone says and says that they have all the features... but how many of these features is proven and recognized and solid in the production environment.

  features of vmware as HA, DTS, SVMOTION, DPM, DRS,... technical of memory reclaimation FT... NIOC, SIOC... VAAI... VDAP... vDS etc... A lot.. even a unique feature of DPM will be enough to save money in cooling and electricity costs... and it is worth to invest in VMware... but how many other sellers have these and proven... these vmware features are not some features... they are real innovation and cutting edge technology...

  5 - journey to the cloud...

  Everyone says that they are cloud... and they can... I'm surpised... others they have yet to reach maturity and has proved in the industry... in the VIRTUALIZATION layer then how is it that they can claim... they want in the cloud.

  6 - support

  It is the key... who is responsible... or head... or who will take possession if a problem has occurred in the critical production...?

  in the Opensource... no body will take... this part, solutions may work or may not... it will be a great solution or you can screw your system... It is therefore a GROPING and LUCK... If there is a bug in the code that will correct? will wait for you to X days or hours until what someone gives a free solution in the internet... for critical system...? Here, you will lose the company... for businesses, they have ALS, and they will solve.

  7-business continuity & disaster recovery

  What happened if my enitre SITE is down? how fast can I bring my services...? .. is it possible to create an ACTIVE/ACTIVE sites... it's the two sites are primary. .. the answer to these are VMware SRM... just a FEW CLICKS of MOUSE...!

  To run a busines... These are very critical... otherwise you will lose the business...

  While there in the open... battery and if something is there... then how fast it can... Can RTO be achieved? -you will not get a perfect answer for this.

  now in the openstack... it is a great software... but who will customize... it... and who will support... train... and how are you going to handle... watch... will it give features as including vmware gives...? ... at what speed you can adopt in your IT... ? and a lot of questions always there to ask and you will get almost no response...

  These software and solutions can be managed and edited... by GIANTS like GOOGLE, facebook... Rackspace... etc.they have the manpower... time... capital... etc... purpose for others... it is not possible...

  now all these openstack... opennebula... KVM... it's free... great... OT of savings... At the end of the DAY, who is responsible if I lose the COMPANY?

  But VMware is expensive... it's true... then who cares... ? If I want to win an F1 race, I need car Ferari... and with a normal car FORD or FIAT... you can't win. the RACE. Here the COST is not the issue... and no body cares... What matters here is... What technology... how it stable is... with which I CAN win a RACE...?

  There is a lot of technique... and other comparisons in a meaningful... These are just my thoughts... and I'm not BIASED... also. From now on... in terms of COST, others can beat VMware... and everyone says this also... But the interms technology... they have the LAST WORD.

• Install Oracle Linux 6 update 2 in vmware fusion

  Then I looked around and it seems that there is a bug in the oracle linux distro that causes the screen to be cut in the installation program.

  The solution which is given anywhere is for vm workstation and go into the settings of the virtual machine, and configure the virtual machine display to have a screen at 1024 x 768.  Save the settings.

  However in vmware fusion 4.1 I don't seem to have that option.

  Does anyone know another solution for this?

  Thank you

  Mike

  Hi dalupus,

  The quick and easy solution is just use the keyboard... on most pages Installer, simply pressing enter move you to the next screen, even if there is no Next button visible.  If you change something on one of the pages of the Setup program, the Enter key may not work... In this case also, Alt-N should be is to click on the button "Next" invisible.  With my keyboard, it's the - N Option; You may need to adjust your keyboard and layout.  I can use this technique to make throughout the Oracle Linux 6 update 2 installation on Fusion here.  After restarting the virtual machine in the second stage of the installation, you will see at least the half top of the keys.  Once the operating system is configured and that you log the guest operating system, follow the instructions in KB to install the correct video driver in the comments.

  If you prefer to do the next button appear correctly from the start, you will need to change the configuration of your virtual machine file to include:

  SVGA. AutoDetect = "FALSE".

  svga.maxWidth = "1024".

  svga.maxHeight = "768".

  Make sure that you remove these two lines, once the client's video driver is set to day, otherwise, the virtual machine display stuck at 1024 x 768.

  I hope this helps!

• What is x 86 all the Techniques of virtualization?

  Dear Experts of VMware;

  I know the ESX(I) have three x 86 virtualization techniques:

  1-binary Translation (The older)

  2-material assistance to the (The one that follows - which have a lot of performance problems due to the lack of MMU virtualization support and lacks to cooperate quickly with the MMU virtualization software)

  3-paravirtualized (The most recent technique it have the ability to change the core of the guest operating system to perform an execution performance by using APIs is communication between the virtual machine and Hypervisor.) This makes using VMware tools and VMI kernel enabled for VMI Linux kernels).

  I also found that the MMU & CPU paravirtual are supported only for 32 bit OS, I have no why he provided only for 32 bit OS.
  

  Finally, I surprised when I know that VMware support is no longer the VMI in future versions of virtualization products.

  
  

  Did I miss something here? or what plan of VMware for virtualization performance? Are it will depend only in the first 2 techniques and stop the paravirtual for CPU & MMU and support it to storage drivers and networking only!?
  

  .... Oh... I'm so confused. !!!

  
  

  Please, I hope that someone support me with the correct answer... or papers...

  
  

  Thanks for the replies.

  By the VMkernel resource management is an essential feature.  Planning enough vCPUs, allocation of memory and conservation and management of I/O is the functional Center of the hypervisor, and is not a trivial task.  Be able to unload things like shadow page tables and output entry/VM VM activity for privileged CPU instructions (interruptions, etc.) leaves more room in the vmkernel for other tasks.

  Paravitrualized ECS (vmxnet) and for guests paravirtualized SCSI controllers will not have anywhere for awhile; they are now required to e/s high-performance of a virtual machine.

  There are a number of documents of the performance under the vSphere technical resources that enter the details on the CPU scheduler and the VMkernel memory management features.

  Thank you

• How does the syncronize feature of VMware Converter 4.2 works?

  The storytelling administration guide follows writes:

  http://www.VMware.com/PDF/vsp_vcc_42_admin_guide.PDF

  Page 10

  You can configure vCenter Converter to synchronize the destination with the source machine virtual machine after

  hot cloning. The synchronization is performed by the transfer from the source to the destination blocks which

  changed during the initial period of cloning. To avoid the loss of data on the virtual machine of destination,

  vCenter Converter can close some Windows services before synchronizing. Based on your

  settings, vCenter Converter stops the selected Windows services so that no critical changes occur on the

  source machine so that the destination is being synchronized.

  From my point of view, it works as follows:

  1.) hot clone of the source to the destination virtual computer computer

  Synronization 2) takes place directly after hot cloning, to get the delta during the initial period of cloning.

  Page 11

  TO

  make sure that the destination virtual machine retains all the blocks that have changed in the source system during

  the first cloning of process, select the Sync feature. With synchronization, if a change occurs

  on the source machine during the initial conversion, vCenter Converter copy to the destination machine

  after the initial conversion is complete.

  The technique that is used to nothing: Windows VSS snapshot

  Page 28

  Restrictions related to the creation of snapshots of Windows Sources

  vCenter Converter uses snapshots VSS to save the State of the source volumes during the hot cloning of physics and

  virtual machines that are running Windows. Instant VSS are also used to synchronize the virtual destination

  machine with the source machine after the initial conversion. Some of the issues related to VSS are inherited in

  vCenter Converter and can prevent the successful completion of your conversion tasks.

  3.) only the combination of the service with synchronization to stop makes sense.

  Page 53

  You can ensure that you don't lose data services that are running on the source machine. You can select

  Which services to stop before vCenter Converter synchronizes the data between the source and

  destination machine. Accordingly, the services do not result in data while the computer source and destination

  are synchronized.

  Import a Windows powered machine means that vCenter Converter copies the data from the source

  machine to the destination machine, while the source computer is still running and generate changes.

  This process is the first transfer of data. You can transfer data for the second time by copying only the

  changes during the first transmission of data. This process is called synchronization.

  What does the second time? I can do the following:

  Back to Monday from 20:00 to 24:00 the Hotcloning of the physical server to virtual.

  Then, to Tuesday 20:00 synchronize the physical server with the virtual and stop the physical server.

  I think that's not possible, two separte the first and the second stage.

  Page 55

  Synchronize the Destination Machine with the changes from the Source Machine

  Import a Windows powered machine means that vCenter Converter copies the data from the source

  machine to the destination machine, while the source computer is still running and generate changes. This

  process is the first transfer of data. You can transfer data for the second time by copying only the changes made

  during the first transfer of data. This process is called synchronization.

  Synchronization is available only for Windows XP or operating systems later source.

  If you resize volumes FAT or shrink NTFS volumes, you cannot use the sync option.

  Prerequisites

  Stop services of source to make sure they don't generate additional changes during synchronization.

  that could lead to data loss.

  Must serve it it I can only do this at the start time of the conversion, when the wizards to configure the conversion tasks is selected.

  In all of this means for me that with synchronization window maintaince than AI based on time, how long is the synchronization and the closure of the physical server and power on the virtual machine.

  Converter 4.2, synchronization occurs just after the cloning process and therefore changes occurred to the source during the period of cloning are also applied to the destination machine. Now, with this version of the converter, it is not possible to separate the tasks of synchronization and cloning (i.e. you can't clone the machine Monday and synchronize this Tuesday).

• price drop of harware virtual to version 7 to version 4

  Hi all

  I'm just felt for the answer to the price drop of harware virtual to version 7 to version 4, is it possible?

  THX

  as I said, using VMware Converter, you will have the possibility to change the hardware version.  You should use atleast version 4.0.1 but I use 4.3. And no, you do not need all VI3 hosts.
