• Extend a datastore in vCenter with virtual machines running

  We have expanded our Volume and unit number logic on our NetApp SATA VMStore from 2 TB to 4 TB, we now want to expand in vCenter, I'm ok to do this within office hours, while VMS are running on the data store?

  Going via configuration - storage - etc etc...

  It should be good. Off-peak hours are preferable, because you must make playback etc.

  This will not affect the virtual machine running inside.

  Unless there is a particular requirement, why not go with 2 TB Lun? I mean add another 2 TB logical unit number rather than add a measure?

• You can enable CDP on a host with virtual machines running?

  I want to activate CDP on my 3 hosts vShpere 4.1. Each host has about 20 guests on this subject. If I activate CDP via putty will affect the network connectivity of the virtual machines running on the vSwitch? Can I move all the VMS hospitality first?

  Hi Letstub,

  There is no need to evacuate your virtual machines from the vSwitch. Enable or disable CDP has no impact on the communications of the network of virtual machines. The following article that explains how to enable CDP mentions this prerequisite:

• Large SQL virtual machines running on ESXi

  Hello

  When you decide to run or do not run large SQL VMs on ESXi, what are the points that you take into consideration?

  -How much memory physical RAM more should the ESXi host at least have in relation to the virtual machine? If I have a Go 96 VM on a host of 144 GB, you would use this room for other virtual machines as well? Would you go to bigger hosts? Or that you would a one-VM-host?

  -In a "a virtual machine by host" scenario, is there still a sufficient reasons to virtualize the VM? VMotion, the portability of the virtual machine, adding disks, disks, resizing easy resize memory still reason enough to virtualize this VM?

  -When I add now Microsoft clustering in the equation, killing VMotion and flexibility, it is always possible to virtualize this SQL Server?

  I know how capable ESXi is the delivery of this workload. I have the white papers of performance on HOW to virtualize SQL successfully. My question is above all on: If you...

  Gabrié

  It is like arguing about policy; There are people with all kinds of views and a large part of it boils down to personal opinions. Some things to consider;

  (1) you do not mention how CRITICISM (aversion to downtime) is the database. If it is super important, certainly looking to HA or even fault tolerance. This increases considerably resources on a virtual machine.

  (2) even if you use one approach "a virtual machine by host", you must make sure that the availability on OTHER hosts in the case where HA is triggered.  So you have basically two hosts per VM

  (3) in view of the above, and how this intensifies that you get in redundancy, HA and FT, you can compare the cost a cluster HA environment.

  We personally, it is facing a prior work. We went with material in the physical server cluster.  In my opinion, if the server is simply great, but didn't need to HA or FT, then I would consider virtualization it. If she needs these features, the fresh material support worsen significantly. Size alone is not a huge problem, assuming you have the SAN space or storage. I am currently supports environments with virtual machines that are more than 1 TB and will work perfectly.

  I hope this helps.

• List of Cluster and the virtual machines running on this group

  Hello

  I am looking for a way to discover all of the virtual machines that belong to a cluster. In other words, I want a list that maps a cluster to all virtual machines running on it.

  In the documentation of the API, I find that "ClousterComputeResouce"has a managed object to "HostSystem" reference. "

  And "HostSystem" is a reference to managed object to the 'VirtualMachine'.

  So I can do it like this: ClusterComputeResource-> ManagedObjectRefence-> ManagedObjectRefence (VirtualMachine)-> whatever_properties_I_need_from_the_VM (HostSystem).

  However, this would cause a lot of ' Vim::get_views"calls within a"foreach"loop." It would be a deterrent to performance as the vCetner in question has ~ 50 clusters and has ~ 3500 running VMs.

  I think this was going to literally kill the VirtualCenter with so many API calls.

  My Question: is there an effective way to find Cluster and their respective VMs in vSphere SDK Perl.

  In vSphere client, we get the tab 'Virtual Machine' when we click on the Cluster and you can see all the virtual machines that belong to this cluster. So I hope that there must be an easier way.

  Thank you.

  Hello

  You don't need the host_view for this action. Why don't you use begin_entity for views of the vm?

  my $cluster = 'cluster1. "

  My $cluster_view = Vim::find_entity_view (view_type-online 'ClusterComputeResource',

  filter => {"name"-online qr / ^ $cluster / I});
  {if ($cluster_view)}
  My $vm_views = Vim::find_entity_views (view_type-online 'VirtualMachine',

  begin_entity => $cluster_view.

  Properties-online ['name']);
  foreach {$vm_ref(@$vm_views) my
  print $vm_ref--> name. » \n » ;

  }

  Hope that helps!

• Virtual machine running on snapshot but there are no spanpshot on the Snapshot Manager.

  Hi all,

  After a backup with VMware Data Recovery failure (error-3960 cannot suspend virtual machine), I have a virtual machine running on snapshot (see attachment) but there is no snapshot on the Snapshot Manager. Is the command to "consolidate" (I have never used this feature) the solution?

  Thank you.

  Marco.

  OK let me explain.

  As the chain of snapshot is not displayed in snapshot Manager, you can correct this problem in two ways.

  1 engage the snapshot command line. If you are uncomfortable in the command line, follow this KB KB VMware: commit snapshots on ESXi host command line if you are not comfortable follow step 2.

  2. create a new snapshot for this virtual machine (this will create a chain of snapshot, and you can see the snapshot in the Snapshot Manager), once the snapshot is created successfully. You can remove the snapshot in the Snapshot Manager.

  Hope this is clear. Let me know if not

• Virtual machines, run extremely slow when the console is consulted 2 virtual machines Windows Server 2008 64-bit, Windows Server 2003 32-bit, 2 VMWare for virtual machine

  I'm in a difficult situtaition here.  I am the daily contact with a new client.  My linux guy, who is also my boss who is very busy, asked me to do some research trying to find answers for what's not on this server. We have a dual Quad Core 2.5 Ghz Lenovo server with 10 GB of ram.  2 500 GB hard drives are Raid 1.  We run Virtual Server VMWare 2 on a Debian with Gnome installation as a user interface for the side of things Linux.  Grub is the boot loader. There are two virtual machines running on the server.  The one machine that serves as a domain controller is a Windows SBS 2008 Server 64 bit, and the secondary machine has no responsibility domain.  The second machine is a Windows Server 2003 32-bit.  the 10 GB of ram 6 GB is allocated to the SBS server and 4 GB to the 2003 server.

  The problem I am running into is that everything is so slow, especially if I connect remotely to do any sort of administration on the network.  Some examples of issues I've noticed is that as soon as I log on the server via Remote Desktop SBS console management Windows Server spike to 80-95% CPU usage and it will not stop unless I close the management console.  Another instance is that if I open Backup Exec 12.5 on the SBS server it will kill the speed of the processor as well.  Long story short, there are a lot of machine to do what we need to do, but something is not configured right and non of us know what it is.  Another point to note is that the server has been in production for about 3 weeks, and the server seemed to have locked up just twice.  My professional guess is that over time, some chose thing is eating causing the crash of the memory.

  Sorry I do not have much technical insight on this topic, but this is the best I have to offer.  Any questions you all have, I'll ask my people and see if I can answer, but I could really use your help here.

  Thank you in advance,

  Heath

  2 things:

  1 you really need hard drives more than 2 in a RAID 1 for proper performance under load. More disks the better. Although I don't think that's what your problem is, he'll probably be the problem Next you will do.

  2. I don't know exactly where the configuration file is on your box of Debian for VMware Server, but you should consider adding the following options in the configuration file (on windows, it's the vmware 'config.ini'):

  prefvmx.minVmMemPct = "100".

  MemTrimRate = 0

  sched.mem.pshare.Enable = "FALSE".

  mainMem.useNamedFile = "FALSE".

  If you do some research, you can read about what these options (the largest is the memory page sharing - it should only be left on if you have a bunch of similar virtual machines running on the same box, that you don't have.) I honestly know why this is on by default, he kills the CPU when virtual machines are running different operating systems). These are the options that I now use standard in VMware Server deployments, with huge performance increases after you have added the. Just give a try.

  Edit: Also make sure that you have installed in your virtual machines VMware tools.

• Impossible to reconnect to a virtual machine running

  Hello

  I removed decadent a virtual machine running in the inventory.

  The machine virtual is critical and cannot be stopped.

  When I try to browse the data store the option "add to the inventory" is grayed out.

  How can I reconnect it to the inventory?

  Alternatively, you can try to reboot the virtual machine in vCenter:

  1 vim - cmd vmsvc/getallvms

  2 vim - cmd vmsvc/reload xx

• cannot select store with virtual machine

  Hello

  I want to configure RDM for a virtual machine that has been powered down. When I chose one to add a ROW to a READ, the "Store with virtual machine" option is grayed out, only 'Specifies the data store' is available. From what I had experienced, by specifying a data store (only the local data store unavailable to its host), this would avoid this VM vmotion when its current host has been disconnected.

  Please correct me if I'm wrong, but what is the reason for which a virtual machine would not be able to choose la carte READ my San to his record?

  You want "cloud." If you have heard of the interest of the industry in the "cloud computing", it's an aspect of it. You create a virtual machine and hand it turns off your COMPUTER service (for a private cloud) or a hosting company (for a public cloud) and don't have to worry about the maintenance of the equipment. See also http://www.vmware.com/solutions/cloud-computing/

  Cloud computing market is still fairly new, and there is no I'm aware of many suppliers. I also expect them to focus on business first rather than individuals, as businesses will be probably easier to bear (homogeneity) and are willing to pay more.

  As others have said, the current accommodation market (which IMO offers only a fraction of the capabilities of a cloud) is mostly about getting a generic instance and tweak to your liking. I guess the underlying architecture of most of the places is a strategy of container - like - this can reach higher densities (because resources from reviews are shared) at the expense of the flexibility (because resources from reviews are shared), but maybe not what you want.

  The only currently existing service on a large scale that allows the download I can think of off the top of my head is Amazon EC2 (which is a strategy of container and not based on VMware products). You are limited to a certain list of grain and the capabilities of the resources and of course must be in their specific file format.

  If you're ready to be your own host, or can find a small hosting provider, Fusion VMS should be able to run on vSphere with minimal changes (vSphere companies target, so it is much more interested in the most characteristic stability.) Some features that work in Fusion do not work on vSphere).

• "Error: failed to get the IP address of the destination virtual machine running the converter to assistance server." with a static IP address

  Hi all

  I'm trying to p2v linux 6.4. It fails with the following message is displayed:

  Error: Cannot get the IP address of the virtual destination machine running the converter assistance server.

  I have seen discussions on this message, but they all refer to dynamic IP address, taken from DHCP, as in my case, I use static IP address.

  In the meantime the p2v (which then breaks down...) I open console support machine and saw a message:

  
  

  eth0 is not a recognized interface.

  Can someone tell me what is happening?

  Hello

  I assume you are using converter 5.5. There is a new feature that allows the selection of the network card. However, it works well in the case of Linux P2V. If you have changed the type of adapter, use 'e1000' or 'auto' and try again.

• If I had virtual machines running 3.5 and I update to 4.0 VMs still work?

  Hey there!

  Well, today I had a request to create a virtual computer that is running Server 2003 x 64.

  I have ESXi 3.5.0 and according to this site, it is not possible to install x 64-bit operating systems.

  The solution is to run ESXi 4.

  I wanted to try and install ESXi 4 on 3.5.0. Virtual machines are in a separate hard disk of the ESXi installation location.

  My question is, once ESXi 4 is running, will the system VMs flowing underneath?

  Are there problems?

  Thank you guys!

  If your host has VT turned on in the bios (not all processors supported by this feature), you can then run 'standard' x 64 vm s on 3.5.  The link that you referenced is if you use paravirtualized VM.  Most of the people do not use paravirtualized.

• Good way to put a static MAC for a virtual machine running on VC 2.5 with ESX 3.5 hosts

  Greetings,

  Could someone tell me if a static addressing mac via VMware VC - slot of the VM client change the settings & gt; Map network & gt; MAC address - the value manual the last way to do. (because we are short VC 2.5 and its in the GUI).

  I saw manal parameters by editing the vmx settings file (requires you to remove the virtual machine from the inventory of the VC. Is that above the new way, if you use Vmotion or does GUI defining a moot point?

  Thank you

  dhayashi

  Hello

  If the MAC is one of the MACs from VMware, then you can set it in the CIV or directly in the VMX. Make sure that the virtual computer is turned off when you change the VMX. If this isn't one of the MACs from VMware, then you will need to have the guest operating system to change the Mac. There are many tools that can do this.

• Support ESXi 5.0 host FC connected tape drives in the virtual machine running symantec backup exec 2012

  Dear Experts,

  We recently purchased C0H19A: StoreEver HP 1/8 G2 6 - LTO Ultrium 6250 CF TapeAutoloader. The purpose is to backup of VMS data, I mean selected data in virtual machines, as for the exchange of data bases email for server accounts database SQL server etc.. We have a full VM backup plan, so using symantec backup exec software.

  We have this configuration:

  -TWO DL 380 Gen8 servers (running UPDATE2 Esxi 5.0), both servers have not all SCSI ports

  -One SINGLE HP P2000 G2 MSA FC Dual Cntrl storage

  -TWO HP SN6000 12 - pt Windows Pwr FC switch

  -HP ADF

  All them above are related to the CF. Symantec backup exec 2012 is also installed on Windows 2008 R2, which is a virtual machine.

  But now, we are unable to see the tape library autoloader through the virtualization layer in the device of machine Manager virtual backup exec. Reading on internet, I also found some details that connected FC tape drives are not supported by the Esxi hosts. We are really stuck in this situation, all the solutions to this. I also read the article from vmware saying configuration for Esxi 4.0 FC tape drives and later versions

  Installation of a physical server windows with Backup Exec 2012 and HBA and connected to above switches FC is the only way to see the ADF? Even after reading articles on the internet, I'm not clear, please guide what solution I have now to get this thing going, I really need to find solution to this.

  Waiting for answers.

  Kind regards

  Hello, I'm a Backup Exec support engineer and yes the method supported is only by connecting the tape drive to a server of physical media.
