• How to find the age of a child and snapshot number snapshot for a virtual machine.

  Hi all

  How to find the age of a snapshot for a virtual machine child count and snapshot.

  This code snippet should help... Assuming that you have the following entries:

  VM (VC:VirtualMachine)

  snapshot (VC:VirtualMachineSnapshot)

  System.log("====== Snapshot details for VM: "+snapshot.config.name+" ======");
  var snapshotTrees = vm.snapshot.rootSnapshotList;
  System.log("Snapshot Tree Count: "+snapshotTrees.length);
  for each (snapshotTree in snapshotTrees){
      showSnapshotInfo(snapshotTree, snapshot);
  }
  
  function showSnapshotInfo(snapshotTree, selectedSnapshot){
      if(selectedSnapshot == snapshotTree.snapshot){
          System.log("====================");
          System.log("Name: "+snapshotTree.name);
          System.log("Id: "+snapshotTree.id);
          System.log("Description: "+snapshotTree.description);
          System.log("createTime: "+snapshotTree.createTime);
          System.log("quiesced: "+snapshotTree.quiesced);

          System.log("backupManifest: "+snapshotTree.backupManifest);
          System.log("snapshot id: "+snapshotTree.snapshot.id);
          System.log("state: "+snapshotTree.state.value);
          var childSnapshotList = snapshotTree.childSnapshotList;

• Change tracking (CTK) block is supported for this virtual machine, but was refused. This will increase the CPU proxy and consumption of IOP.

  I have problems with a client of VMware image-level in an EMC Avamar backup.  So far, we have not been able to find information about this message in the backup log file.  It is originally the backup to take a very long period of time (on average 10-11 hours).

  2014-02-28 14:20:57 avvcbimage < 14681 > Info: change tracking (CTK) block is supported for this virtual machine, but was refused. This will increase the CPU proxy and consumption of IOP.

  We cannot determine why CBT is "denied".  Has anyone here run across this issue before or seen any other type of backup VMware image have denied CBT?

  Everything I checked watch that CBT is successfully activated since the file vmx for the customer to the Avamar config.

  ESXi host is Enterprise Plus 4.1.0 260247

  After spending some time on this issue, the ultimate resolution withdrew the Avamar vm and then add it again.  After that, CBT began to work properly.  It seems that there is a parameter that has been 'stuck' pertaining to this virtual machine that wasn't behaving properly.

• ESXi 5 - Longmode is disabled for this virtual machine.

  Hello

  I installed ESXi 5.0.0 469512 on a Dell Optiplex 755 with Intel Core 2 Duo E8400 processor @ 3 .00GHz with 4 GB of RAM. In the BIOS (version A21), I have the following options enabled:

  Performance-

  Virtualization: on

  VT for direct i/o: on

  Execution of trust: on

  Security-

  TPM security: on

  Activation of the TPM secure: assets

  Execute Disable: on

  I am unable to run any 64-bit OSs. For example, when I try to start vMA VM 5.0, I get the following Message from the Virtual Machine:

  "This virtual machine is configured for 64-bit operating systems. However, the 64-bit mode is not possible.

  Longmode is disabled for this virtual machine.
  For more information, see http://VMware.com/info?id=152 .
  Continue without 64 bit support? »

  I ran the "processor check for 64-bit compatibility ' and if confirmed I can run 64-bit guest OS.

  I tried to add vhv.allow = "TRUE" to/etc/vmware/config, but it made no difference.

  In the vmware.log file is that it makes meantion 'virtualization software is incompatible with the long mode on this platform. Disabling longmode. "I have attached the full logfile for details.

  Any help will be greatly appreciated.

  Thank you Paul.

  According to the log file

  Frequent: MSR 0x3a = 0x3--> currently '0011', should be 'x 1 x 1 "'.

  VT - x is not enabled (bit 0 + 2 required)

  There were other debates, where that allows "Trusted execution" cause problems. I "suggest that you configure the settings of the BIOS as follows:"

  Performance-

  Virtualization: on (assuming it's VT - x)

  VT for direct i/o: Off (unless you need it)

  Execution of trust: Off

  Security-

  The TPM secure security: Off

  Activation of the TPM secure: inactive

  Execute Disable: on

  After you change the settings, you will need to power cycle the system.

• Affinity processor for a virtual machine

  I have a lot of CPU 8 on which I have installed ESX 3.5 U3. I also created a virtual machine Windows 2003 Server SP2 with 2 CPU is assigned to the.

  I'm trying to set the processor affinity for this virtual machine to use 2 of my physical processors. I see now on the tab Advanced CPU, I am able to select all available 8 physics of the processor. So now I'm a bit confused regarding if VMware allows scaling of my machine virtual to use all 8 CPU when my virtual machine is only 2 CPU?

  Now if the above is true, and I am to be allowed to set the affinity of the virtual machine to the all 8 CPU, then why is this maximum limit of the processor for a virtual machine is only 4? A stupid question probably but I'm really confused?  :|

  Hi confused,

  Yes, the user interface is a bit confusing. As RParker said, basically what you are doing when you assign the processor affinity are to identify the nuclei on which the vCPU is eligible to run on. At no time will be the VM scheduled to be run on carrots than what there vCPUs, so he will never have access to a capacity more than expected.

  The processor affinity is one of those features that's been around since 'the beginning' and its utility is really a bit blurred. I've heard of cases where users were running Citrix workloads configured with 2 vCPU and assigned the processor affinity for each virtual computer with the result of improving the performance. I wonder this because I never saw myself, and have a decent knowledge of how works the vmkernel Scheduler, it make much sense.

  I would encourage you (and anyone else reading this) essentially forget that the processor affinity is an option. Use it can cause significant performance degradation (if, for example, you pin a VM through two nodes NUMA, rather than keep vCPUs all in the same node) and break features (VMotion, DRS and who knows what else in the future).

• Local and remote to the same virtual machine replication?

  Is it possible to configure replication for a virtual machine to replicate locally and remotely?

  For example:

  ServerA is my server I need to replicate.

  I set up replication for this VM ServerA to storage replicated in the same site (local)

  I opened the replication again for ServerA VM and I can only see/manage this replication.

  I would like to reproduce ServerA VM offisite in a remote cluster of VCenter for DR purposes.

  
  

  Is this possible? What I am doing wrong?

  same source VM cannot be replicated on the two sites with vSphere replication targets.

  If you use replication level storage table between the source to the target and the second replication, you use the replication of vSphere, it would be a different story.

• SRM 5.5 - vSphere replication - error: impossible to reverse the replication for the Virtual Machine. A snapshot operation cannot be performed

  Hi all, we have just run a test DR failover of a couple of virtual machines in our protected our failover site and all site swung perfectly, two virtual machines came online and all applications work well. However when we cam to r-eprotect machines virtual, we get some errors.

  One of the virtual machines seems to have lived the reprotect end process, it is still running, but has not moved to 89% for some time. The virtual machine has a couple of grand (a little less than 2 TB) VMDK. slow progress is just a consequence of the large VMDK?

  More worrisome is the virtual machine which don't reprotect at all. It generates an error whenever I click on the "Restore" button (error: impossible to reverse the replication for the Virtual Machine.) A snapshot operation can not be performed).

  
  Does anyone have any ideas as to the cause?

  Thanks in advance for any help.

  Andy

  Finally got to the bottom of this. The issue was that reprotect SRM work was trying to dispel any snapshots that were taken on the computer object virtual destination in VMWare, but could not clean snapshots.

  The reason why snapshots would not consolidate was because it was snapshots of temporary VEEAM who in fact any snapshot file listed in the VSAN data store. So when we looked through the browser data store, no snapshot file existed in the virtual computers folder. Trying a manual removal also failed.

  To fix this, we created a snapshot of the virtual machine in the original data center (note is the engine to the bottom of the virtual machine), this effect was to get rid of the 'fade' snapshot that was visible in the Snapshot Manager that VEEAM backup had left behind. Once this had disappeared, the reprotect back to DCA worked perfectly.

• A suspended snapshot could not be created for the virtual machine (DC) ha-data center (DC) \vm\VMware vCenter Server Appliance.

  Hello gentlemen,

  Hello

  I found the solution.

  I disabled the JOB BE general relativity.

  and the host where the virtual machine belong was not the right time. No Ntp server has been configured.

  I did and now there works.

  I think that the problem can come from this.

• Definition of levels of booking for a virtual machine

  The vcloud usage meter says:

  NET points = (vGB hours X points per 1 GB reserved RAM) / hours per month

  
  

  A month calendar of 30 days, a service provider uses the vCloud package provider services - first Edition to configure its virtual machine with 16 vGB for 15 days and 48 vGB 15 days remaining. The level of booking for the virtual machine is set to 75 percent for the whole month.

  15 days x 24 hours x 16 vGB x 0.75 = 4 320 hours of vGB

  15 days x 24 hours x 24 vGB (vGB 48 x 0.75 but capped at 24 GB) = 8 640 hours of vGB

  Total number of hours of vGB = 12 960 hours of vGB

  Total points = 12 960 vGB hours ÷ 720 hours / month x 7 points (for Prime Minister) = 126 points

  Where "the level of booking' for a virtual machine?  Is - this talk on VM bookings each parameter in vCenter Server, or do something to the extent of consumption vCloud himself?

  Hello. The reservation level is set for each virtual machine, using a vSphere Client or API.

• VCenter shows a network for a virtual machine that is not associated with any host

  I have a win2k3 VM who at one point had a network assigned to him called "MONITORING".  This network is configured is no longer in the ESXi (5.5) environment.  The virtual machine is connected to a network called "PRD-SURVEILLANCE" which is correct.  It's not really cause a problem, but I can't find a way to get rid of the object of MONITORING network.

  In VCenter MONITORING networks has a VM of 1 meter, the number of hosts of 0.  I also see it in the VM - dialog box, change the settings, but there is no option to remove it.  Profile Image to the virtual machine is version 10 so I can't use the old Client of VI to try to remove it.  I have checked each host and do not see this listed network object.

  I tried to restart the VM, it migration between hosts, changing its network of SURVEILLANCE of PRD to another network and vice versa and close - remove NIC and add a new card network.  MONITORING legacy network still appears in the config.

  For the virtual machine's .vmx file shows that the correct network: ethernet0.networkName = 'RDP-ANALYSIS '.

  Any suggestions on how I can remove the artifact of MONITORING network?

  The virtual machine has a preview that was created at the time where the MONITORING network was still affected?

• Help: Cannot clone a snapshot for a virtual machine that is turned off

  Hi guys

  I am currently using VMWare Workstation 10.0.3 build-1895310

  (The latest available at the time of writing)

  I want to create a clone of a snapshot.

  The snapshot is on the two snapshots behind 'You are here' - the current state.

  The computer virtual running windows server 2012.

  The virtual machine is completely turned off.

  (the virtual machine was turned off within the BONE, and no 'Power Off' option is available in the menu 'Power' after the OS is turned off, indicating (as far as I can tell) that the virtual machine is turned off completely)

  However, when you try to create a clone of the snapshot, the dialog box indicates that the virtual machine must be fed first (which I think it is) before making a clone.

  The only option available in the dialog box is "Cancel". (ie - the cloning process cannot continue)

  The attached picture shows the dialog of Clone, indicating the issue - and behind it, the engine power VM off

  (I'm trying to clone the snapshot "Installation")

  In other words, I have a completely powered off power VM (as far as I know), but it is impossible to create a clone of a snapshot, as VMWare seems to think that it is always active, for some unknown reason...

  Am I something wrong / missing something?

  Please advise...

  Thanks in advance

  James

  Welcome to the community,

  the reason is that the virtual machine has been turned on at the time you created the snapshot. What you can do is to clone the virtual disk manually using the command line of vmware-vdiskmanager (using the snapshot required as the source hard) and then create a new virtual machine by using the virtual disk cloned rather than creating a new.

• Disable the clichés for individual virtual machines?

  Hi all

  Is it possible to disable support for snapshot for individual virtual machines, perhaps via a parameter for it?  Or is the closest answer you to put all its virtual disks in independent mode?  Try to see how to better meet the requirements that certain suppliers impose that the VM/device does not catch instant and thought that the best solution is to disable the feature for the specific VM (s) only.  Thank you!

  You can watch the snapshot.maxSnapshots configuration setting. See KB 1031280 for more information.
