• Change of that flag - hot virtual CPU add

  Hello

  I'm trying to build an application that will add/remove of CPU and memory to a machine virtual a VApp.

  I currently have the code to add.

  What I need is to understand the options 'Add a virtual CPU hot' and 'Hot-memory add' how to define those who through the API? And do I need to change in order to add new CPU/memory?

  Thank you

  Hen

  Hi Henrique,

  Basically the virtual CPU/memory hot add means that modifing the number of CPU / memory of the virtual machine, the virtual machine is running.

  In the API, you don't need to set options to do - simply start the virtual machine and to try to change - even as usual editing operation.

  Note that are are some requirements to perform "HOT ADD" operations, so if some of the requirements is not fullfilled "hot add" operation will fail. For example, this feature is added in VC 4.0, so the version of the VC on which runs the cloud must be at least 4.0 VC. For other requirements on the add feature hot, you can refer to the location of the following link:

  I hope this helps! Please write if you have questions.

• Basic principles of virtual CPU

  Dear all,

  Can someone share the basic principles of the virtual CPU & its architecture?

  We want to know, that UC will get accessible by each VM below cases:

  Case 1:

  Physical server: 2 CPU (6 cores)

  VMS: Total of 3 amendments

  

  Case 2:

  Physical server: 4 CPU (6 cores)

  VMS: Total of 3 amendments

  According to the discussion, I conclude that 1 core = 1 vCPU?

  And in the affirmative, please give me the documentation in this regard.

  FYI - Hyper V is statingthat capacity planning Guide is 8 vCPU per processor.

  No, it's not really a direct relationship with 1 base = vCPU, in the case that you "bind" a carrot to a vCPU. Several virtual machines may use the same kernel, just not the same millisecond.

  Allow to use the said you have only one physical CPU with only 1 core, you can always have 2 virtual machines with one vCPU each. Or 4 virtual machine or VM 16 or any other number. Guest for the processor operating system needs, the VMkernel to increase access between the vCPUs on time to the physical basis.

• Why my doesn´t OS Win2008 recognizes the vSMP (virtual CPU) 6 assigned, will only recognize vSMP 4.

  Hello

  Anyone know why my VM Win2008 OS doesn´t recognize the vSMP (virtual CPU) assigned 6 and do recognize that 4 vSMP?.

  I have the correct license for VSphere and VCenter, also in the guest OS device manager, I can see the six vCPUs but in the System Properties window, I can see only four vCPUs.

  I m running on ESX 4.0

  I hope someone can help me on this problem.

  P.S. I have attached images of system properties and Device Manager

  Thanks in advance!

• Incompatible CPU question

  HI guys

  I have two questions, I think it's related

  Overview

  I have a gen second i7 CPU, which I activated the VT in the Bios and using Vmware Workstation 8 I configure vCenter Server 5 and two VMS Esxi 5 workstation 8, everything he walks.

  1. my first question is when I go to deploy a computer virtual on one of the host ESXi 5 that will run Server 2003 64-bit, I get the error CPU host is not compatible with the requirements of the VMS to CPUID level 0 x 8000001 registry "edx". the tired host: 0000:0000:0001:0000:0000:1000:0000:0000 required xx1x:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx inconsistency detected for these features: * Longmode; required when a virtual machine is configured for 64-bit guest OS. When I try to turn on the Server 2003 64-bit VM

  2. when I click with the right button on my cluster in vcenter 5 and choose change settings and choose VMware EVC and click the VCA mode and select Activate CVS for Intel hosts all the selections in the drop-down list give me error 'Enhanced vMotion compatibility (EVC) cannot be enabled because the cluster contains hosts that lack of HCL. VCA.

  I checked the CPU Compatible table and this CPU is supported is an Inter Core i7 - 2620M (2.7 GHz)

  Can someone help me with this problem

  Welcome to the community,

  just to confirm, you create the VM ESXi with hardware Version 8 and activate/check 'Virtualiser EPT-x/Intel VT or AMD-V/IVR' in the settings of the processor of the ESXi VM?

  If this is the case and it still does not work, please attach vmware.log the ESXi host and vmware.log customer Windows 2003 nested in your next post.

• HT and virtual CPU setup

  We have the following server configuration (and I know it's a pretty old beast)

  ESXi 4.0 on a Dell Poweredge 1850

  CPU cores: 2 x 3 GHz Xeon

  Memory: 4 GB

  Hyperthreading: assets

  Processor sockets: 2

  Cores per socket: 1

  Logical processors: 4

  We run 2 machines on this subject. Probably 2 times Windows server 2008, but it could also be an installation of 2003. My question is, do I have to enable hyperthreading and how do I configure the virtual processor?

  At the moment we do not know how to set up. Should I activate 2 cpu on both machines, 4 cpu or just one? Or do I have to disable the HT at all? We do not know what to do with it. I don't know that the application server is not aware HT.

  I ask this to make the best use of the limited resources available to us. Buying a different server would be the best option, but it will not happen ;(

  Greetings,

  Joris

  Enable hyperthreading - it will give the vmkernel more logical processors to plan virtual processors and others have said to start with a single vCPU and only add extra if your need for and if the applications are multithreaded.

• Virtualized vCenter Question

  I know there are a lot of debates on vCenter server virtualization, but I have a question in particular. It used to be that if you had a virtualized VirtualCenter server and it stopped, you wouldn't be able to bring up because the ESX Server reports that there were not enough licenses to start the virtual machine. I was wondering if it is still a problem with VMware ESXi 4.0 or 4.1? From what I read in the manual, the vCenter license inventory gives a key that is stored locally on the ESX Server so that it will follow the server anywhere where he can go, even to another server vCenter. This is why the ESXi server, once he had a key, would always its own key, eliminating the above license loop. Can someone tell me if I'm wrong or has any detail more than what I have?

  Sincerely,

  Christopher Beard

  vSphere4 is allowed by key, so you will have no problem by rebooting your vCenter VM, as it's just another guest on a host ESX (i).

• ESXi virtual networking question

  Hey everybody,

  I installed Astaro Security Gateway as a virtual machine under ESXi 3.5 Update 3. The installation went successfully and I configured the Astaro to use two VNic (eth0 and eth1). I set up eth0 on the Astaro to use 192.168.2.100

  My question is: how would I be able to access the WebAdmin of this (192.168.2.100:4444) gateway from a remote machine (i.e. my laptop under VI Client)?

  Here are some more in-depth details of config:

  ESXi IP = 192.168.0.187 (provided by our physical switch/DHCP server)

  Under Configuration - & gt; Networking, I see not what follows (see attached photo)

  Help is always greatly appreciated!

  Thank you!!!

  

  You have reason vmnic1 is not used - using the second physical NIC (vmnic1) you will need or create a second virtual sritch by right-clicking on the network link add or by adding the vmnic1 to vswitch0 to create a NIC team.

• PowerEdge R720 virtual disk question

  Hi, our company has bought a Dell PowerEdge R720. I tried to use the lifecycle controller in RAID configuration. At the start, it has 3 500 GB SAS HARD drive, but I ordered 2 x 320 GB additional SAS being what I intend to do it, use the 2 x 320 GB like OS install as RAID 1 and RAID 5 on the default 3 x 500 GB, but for some reason any, whenever I have configure RAID , either on the two 320 or 3 x 500 GB, it shows just a virtual disk, 2 x 320 GB or 500 GB x 3, I see not two for RAID 1 and RAID 5 virtual disks. Am I missing something here? or I have to perform an extra step?

  Kind regards

  Jeff

  Hello Jeff,.

  If you try to install the operating system through the lifecycle controller method. You must have the latest lifecycle controller OS driver pack installed in your system. For the latest driver pack OS, please download from our support http://support.dell.com/ site by entering you service number and download OS Driver pack drivers.

  You can update the OS driver pack thorugh iDRAC GUI or through the lifecycle controller GUI and once after the OS driver pack update. When you try to deploy the operating system through the life cycle of the controller, you will appear on the list of supported operating systems and you can select the operating system you want to install by mounting the image operating system or DVD media connected to the system.

  Please let me know if you have any question.

  Thanks, Neeraj

• Satellite M65-S809: change in CPU Question

  I have toshiba satellite M65-S809 CPU pentium M740. I would like to change processor pentium M770. Can I do this? What is the highest quality of CUT, I can go to?

  Hello

  THEORETICAL, it s possible. If you are a technician who is familiar with these machines, which has the appropriate tools (a few special screwdriver, the right stick, cooling...) and the know-how to disassemble and reassemble the machine, the software that is necessary to reconfigure the Bios (because of the new processor) and if you don t mind not you won´t have a performance huge gain then feel free to do so.

  In practice, it s is not possible, since you really won´t benefit from the upgrade to next available processor, which in your case, already one of the top-of-the-cream...

  So, if I were you I do so wouldn.

• Satellite Pro A60: Upgrade CPU Questions

  I took my laptop apart before, and I remember that I was able to remove the CPU.
  My A60 is the lower part of the range as far as I KNOW, 2.8 ghz Celeron, 40GB HDD and DVD-ROM/CD-RW. I've since added 512 MB of RAM and a LiteOn DVD +-RW drive.
  What type of CPU would be a direct exchange?
  I was looking at my manual, A60 were sold with P4 3.06 GHz.

  I would be able to put in a 533FSB, 3.06 GHz in my laptop?

  Thank you

  Hello

  As far as I know the Satellite Pro A60 was delivered with these processors:
  Mobile-Intel-Pentium 4 processor - HT 518 (2.8 G), 532 (3.06 G) CPU, CPU 538 (3.2 G)
  Intel-Celeron CPU CPU CPU CPU 350 (3.2 G) 345(3.066G) 340(2.93G) 335(2.8G)

  So in this case, I think that you can only use these processors

• ESXi VM virtual network question

  I have two virtual machines on ESXi

  1 Sophos UTM (assigned 'NET' and 'LAN' physical network interface)

  2 Ubuntu server (not assigned any physical network interface still)

  If I assign a new physical network interface 'LAN2"Sophos and also assign another new interface for ubuntu server network, then they will be connected through a physical cable, ubuntu server will be under sophos. However, I want to know is - it possible to do it with virtual on ESXi because that I have enough physical network interface to which their responsibilities.

  Thank you.

  If I understand correctly, you need a direct link between these two VMs running on the same host ESXi!

  In this case you don't need no physical connection. Simply create a new vSwitch without any rising (vmnic) and connect two virtual machines to a portgroup VM on this vSwitch.

• Compatibility of hardware/VM virtual upgrade questions

  Hi all

  We are about to upgrade the virtual hardware (VM compatibility) on 800 virtual machines from 7 to 9 on our environment vSphere 5.1. I read about the problems with the hidden network adapters when the card is moved to another location on the virtual PCI bus during the upgrade. I tested the upgrade virtual hardware with multiple virtual machines, but none of them showed this behavior.

  I know not how to solve the problem, but now I'm looking for real-world experiences.

  1. What percentage will I fail?
  2. Are there useful tips, tools or scripts to facilitate the research process and fixing VMs failed?
  3. What is initially a map to move to a position about the virtual PCI bus (I can "predict" which VMs will have a network card hidden, for example a combination of a specific operating system and certain type of pci device)?

  Kind regards

  Alfredj.

  Last week, we upgraded the virtual equipment of hardware form 500 VMs 7 to 9 (vmx-09) version. Overall, it went well, with the exception of some Windows 2000 and Windows 2003 servers. We experienced a problem that is described in an article named "Windows 2003 virtual machine loses access to the locally stored profile after upgrading the hardware version (2009762)":

  "After the upgrade to a virtual machine to Windows 2003 to version 8 material, you may encounter these problems:

  • You will lose access to locally stored profile.
  • Trying to connect will fail with the error:
  • Windows cannot find the locally stored profile: insufficient security rights or a local file damaged. Windows has connected you with a temporary profile any setting you make will not be saved. »

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=2009762

  Power down the virtual machine and affecting the video card 4 MB memory in 'Change settings' VM has solved the problem for all virtual machines (see article).

  Thank you all for contributing to this topic.

• CPU question

  Just Imagine Esxi host is configured with 1 socket with processor core and processor 3 GHz speed and booking Hotel and configured limit is 1 GHz is for each virtual machine and we have 3 VM can my LCPU supports the treatment instructions all at the same time coming for those 3 VMS simultaneously or not?

  At the same time?  No - its timesliced - only 1 vCPU's always active on the heart at a time.

  But, because you limit each vCPU to 1 GHz, you won't see an apparent difference.
