• What is the size of the 1st copy of Vmware snapshot delta

  If I understand instant, it creates a copy of your image.when delta you first create the snapshot, the snapshot (hard) size is a few megabytes (1000 k or more) and the size of the RAM.

  Example - my primary VM's with 4 GB of RAM and 30 GB of disk. the VMDK file size is 30 GB

  first preview, file snapshot.vmdk will be created which will be around 1000 k

  We will create a file over 4 GB RAM

  space required for the SNAPSHOT so total is 4 GB + 1000 k is this correct?

  Now, if I use instant, it can push up to the original size of VM primary, means it can grow up to 30 GB.

  that mean, when I restart the snapshot virtual machine size will be 60 GB?

  Please advice

  Concerning

  Avinash

  Disk space required when you create a snapshot depends on whether the virtual machine is turned on or off. What you describe on the file .vmsn is correct for the virtual computer power on. The .vmsn file contains the State of the virtual machine (memory) as well as its configuration (.vmx file). With the virtual machine off there is not need to backup the memory so that the file is only a few hundred bytes in size.

  The initial sizes for files hard depending on size delta set virtual disk service, since delta files are fragmented files that contain metadata in addition to the user data. It also makes a difference if the virtual machine is turned on or off.

  ..., when I restart the snapshot of the VM size will be 60 GB?

  No, snapshots files store only modified data blocks that are written with the active snapshot. Each of these blocks of data points to the original location in the basic disk. So if delete you / consolidate these blocks are written to the original location in the Basic virtual disk file.

  Please take a look at for example http://kb.vmware.com/kb/1015180 which explains the functioning of snapshots in VMware products.

• Urgent need help regarding the deletion of snapshots /... Hilfe bei VMware Snapshots löschen

  Hello

  I have a VM and there is an existing snapshot.

  I chose Delete instead of delete.

  Is the snapshot still consolidate virtual machine or if the changes are lost?

  I mean because it was the last snapshot or sole, both delete and delete all did the same thing.

  Please give me a Feedback.

  See you soon

• Path to script and automate the vmkfstools command?

  Very long story short, running vSphere 5, I need a way to execute the command 'vmkfstools y 60' against my stores of data to recover free space on my table of Compellent SAN.

  This article explains the command and the object: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 2014849

  From one or more hosts, I so need to go into each VMFS data store and run the command "vmkfstools y XX" to reclaim space. Otherwise the Compellent table see SVMotion jobs and snapshots as "new entries" and never release the free space.

  To automate this, I would use PowerCLI and maybe just run the script as a scheduled my vSphere Server task.

  I understand also the VMA device can do this kind of stuff, but I don't understand how to automate/schedule tasks with it more I prefer using PowerCLI.

  Anyway, sorry for the question noob and thanks in advance. Any help is very appreciated!

  The problem is we use thin Volumes put into service on a Board of 3par, with T10 off Unmap (which is now the default) freeing up space by deleting a virtual machine or by a storage vmotion means space gets released to the VMWare/data store layer and can be reused by Vpshere but he is not recovered at the Array level , delivering a vmkfstools, writes a file in the data store removes it returns T10Unmap to the matrix, the 3par then and returns this space to the free pool. It works when we manually we just want until VMWare decide UNMAP turn automate it.

• Update the VMware tools cluster HA/FT

  We have a cluster running multiple 5.1 ESXi hosts and a 5.0 ESXi host. The virtual machine running on 5.1 guests show their tools VMWare is obsolete, but the virtual machine running on the 5.0 show their tools as being COMMON since with each new version of ESX, VMWare tools must also be updated. My question is: If we update VMware tools on virtual machines on 5.1, guests will be able to run on the host 5.0 if necessary? Therefore, an active cluster HA/IP hosts automatically migrated to guests according to load, etc.

  Any help is appreciated. Thank you.

  You can use the "product VMware interoperability matrices" to check compatibility. See the attached screenshot where you can see that running the ESXi 5.1 on ESXi hosts tools 5.0 is supported.

• questions to the vmware horizon workspace

  Hi guys

  I implemented the vmware horizon workspace in my test environment. It works very well. but now I have two questions:

  1. is it possible to add storage smb from a windows file server to the device of data? I would like to automatically synchronize the directory on the file server windows with vmware view on appliance workspace data. and for all the users in my domain. (so I think that the vmware agent horizon is not the right tool for this action)

  2. is it possible to implement authentication twolayer? I use two layers for vmware view horizon in this workshop, but I can't find any documentation or the button for twolayer auth in the vmware horizon workspace

  Thank you much for the help

  Kind regards

  Hello..

  I'm glad you like what you see so far...

  1 no, today it is not possible to add Windows shares data.

  2 horizon 1.0 workspace supports RSA Secure ID for two-factor authentication.

• Several considerations are I/O to the vm to go back to the last snapshot before starting mass?

  We have an environment Vsphere 4 with 8 hosts esxi by cluster.  In this group, we have a 512 GB which holds all the linked clones and master vms data store.  This is of course a test environment...

  We need to start to 30 virtual machines both to perform automated tests.  In the past these 30 vms would be quick and easy start without problems.  Recently, we have begun saying the vms (via vmware API) to restore the vms to the last snapshot system before starting.  This has made the EXTREMELY long vm startup process and we cause problems.

  So, I guess that going back to the last snapshot is whats is the problem?  My questions are:

  (1) correct, it's the instant return the cause?

  (2) indeed, what happens when you start a virtual machine and it loses any changes is when the last on and just comes back?

  (3) is it just kill our I/O?  What else does?

  If it is a problem of e/s SAN then I can look at to balance our load LUNS, etc. but first, I need to know what is happening under the hood to properly address this.  Is there another method to reach our ultimate goal without causing such performance issues?

  Yes, it's what I would say.  Spread your VM snapshot across different data warehouses as much as possible, who can help with your distribution of IO.

  Lacking that, I can't see much else you can do.  Given your criteria for the scripts, and a simpler approach, I see your point to keep things simple and unified.  I have a better solution for you.

• Update the VMWare tools on all machines virtual Windows

  Is it possible to use the PowerCLI update the VMWare tools on all virtual Windows machines to the latest version. I know I can do this individuall but I wanted to see if there a way to use something similar to a for each loop through a virtual machine at a time. I'm new to the power of vmware and the vix api cli and it's the first task I am trying automate (automating installation of all guests including linux would be perfect if I could loop through all clients using the same command). I am a new detailed explanations would be greatly appreciated.

  Thank you

  Loren

  It's pretty simple in his PowerCLI, you combine just 2 cmdlets with a pipeline.

  Get - VM | Update-Tools

  You can make the choice of the guests a little more complex.

  For example:

  Get-VM-name Srv * | Update-Tools

  will update only the tools on customers whose name starts with SRV.

  See the cmdlet Get - VM for more details.

  You can also set it update tools should immediately reboot if necessary.

  What you can do with the NoReboot parameter on the cmdlet Update-Tools .

  Get-VM-name Srv * | Update-tools - NoReboot

• Script to automate the affinity of the crib of DRS-groups

  Hello

  I am trying to automate the rules of affinity for the drs Group Manager. The idea is to let some virtual machines running on

  assigned to the esx host (type 'Run VMs on Hosts' / 'Should run on hosts in the group').

  Background: we have esx hosts in two data centers interconnected 10 giga with a metrocluster netapp on each site hosting the nfs exports. I created two groups of type "Host DRS Groups" (in datacenter esx host a go into one, hosts datacenter b go the other) and two groups of type 'Machine virtual DRS Groups' (virtual machines hosted on export nfs one go into one, while the virtual machines hosted on nfs export b go the other). In this way, we can prevent nfs/iscsi traffic across data centers.

  Create the rules manually in a small cluster works. However with dozens of virtual machines in the other groups, there must be a way to automate the task and that it is regualary. I let powercli generate a list of VMS according to nfs export (hard location is either the field a or site b) then import the given in the Virtual Machine DRS group concerned.

  Using get-drsrule-Cluster 'cluster ' | Export-CliXml does not display a details for groups of DRS HOST or Virtual Machine DRS. Is it possible to do it at all? I recon using set-drsrule let me import rules.

  Any help / ideas is appreceated.

  Concerning

  Sascha

  The current DrsRule cmdlets do not, all I know, allows you to work with groups of DRS.

  As an alternative, you can use the ReconfigureComputeResource method that is available.

  The script should look like this

  $clusterName = "MyCluster"
  $cluster = Get-Cluster -Name $clusterName
  
   $spec = New-Object VMware.Vim.ClusterConfigSpecEx
  $groupVM = New-Object VMware.Vim.ClusterGroupSpec $groupVM.operation = "add" $groupVM.Info = New-Object VMware.Vim.ClusterVmGroup $groupVM.Info.Name = "Grouped VM" 
  
  Get-VM -Name MyVM1* | %{
      $groupVM.Info.VM += $_.Extensiondata.MoRef
  }
  $spec.GroupSpec += $groupVM
  $groupESX = New-Object VMware.Vim.ClusterGroupSpec $groupESX.operation = "add"$groupESX.Info = New-Object VMware.Vim.ClusterHostGroup$groupESX.Info.Name = "Grouped Host"
  
  Get-VMHost -Name MyHost1* | %{
      $groupESX.Info.Host += $_.Extensiondata.MoRef
  }
  $spec.GroupSpec += $groupESX
  $rule = New-Object VMware.Vim.ClusterRuleSpec$rule.operation = "add"$rule.info = New-Object VMware.Vim.ClusterVmHostRuleInfo$rule.info.enabled = $true$rule.info.name = "Test DRS group rule"$rule.info.mandatory = $true$rule.info.vmGroupName = "Grouped VM"$rule.info.affineHostGroupName = "Group Host"$spec.RulesSpec += $rule
  $cluster.ExtensionData.ReconfigureComputeResource($spec,$true)
  
  The script first creates 2 DRS groups. One with the VMs and one with the ESX(i) servers.
  

  In the example, there all customers whose name starts with "MyVM1" for a group and all hosts whose name begins with "MyHost1" to the other group.

  These 2 selections will of course be changed for your configuration. Let me know what selection rules you want to implement for virtual machines and hosts and I can update the script.

  The script then creates a rule. Note that the rule specifies $true for the "required" property

  This means that a virtual machine will not be powered on if the placement host does not match the rule.

  The 2nd parameter to the ReconfigureComputeResource method allows you to specify if the changes defined in the $spec to add or not.

  If it's not $true all your cluster settings, except for the groups and the rule will be deleted. So, attention!

• 'The installer does a not install automatically the mouse driver.  This driver must be installed manually. »

  I just installed VMware Workstation 7.1.3 and when I upgraded VMware on a Windows 7 Ultimate x 64 guest tools, I received the following error message:

  The Setup program has not automatically install the mouse driver.  This driver must be installed manually.

  Everything seems to work fine and there is no problem, indicated in the Device Manager.  My mouse driver (i.e. the VMware pointing device) is v12.4.0.6 and is dated 17/11/2009.

  Someone else has encountered this and is there a solution for this?

  Note that VMware Tools installed in Windows Server 2008 R2 x 64 with no problems.

  Microsoft install (MSI) is a strange thing, these problems occur.

  The best way to update the VMWare Tools is to delete (and all other Windows drivers too), then install the new version.

  There is no solution to your problem.

• Fully automate the addition of a datasoter via PowerCLI

  Thank you

  The Select-Object cmdlet does not return the name of the LUN as a string, but as a ScsiLunImpl object.

  The New-Datatsore cmdlet requires a string for the - Path parameter.

  You can do

  $con = (Get-ScsiLun).CanonicalName
  New-Datastore -VMHost 192.168.1.1 -Name newDS -Path $con -Vmfs -BlockSizeMB 1

• Storage on iSCSI - mounted directly from the VMware virtual disks

  I am setting up a HUB/CASE/box Server mailbox of all-in-one for fewer than 500 users on a Windows 2008 R2 virtual machine and am about to configure the storage I need. The two words that I can't wait to hear more from Microsoft PSS is "not recommended" or "not supported." I have a Dell Equalogic PS6000 and have the ability to 'direct attached' compared to the VMware virtual disks for storage of mailbox databases. We run vSphere with vMotion, etc..

  Using virtual disks bad practice? Advantages or disadvantages I should know about? Adding a layer of complexity that might come back to bite me?

  I have a very similar setup and am currently using directly attached iSCSI volumes EqualLogic berries for my Exchange 2007 mailbox stores.  I also have the role of running UNIFIED messaging that works in fact remarkably well even if everything is running on a virtual machine.

  It was in large part because the EqualLogic recommendations had to use directly attached volumes so that taking snapshots multi-application/replication tools worked correctly.  If the Exchange mailboxes are held on a VMFS volume, then Tools EqualLogic will not be able to get to them.

  Microsoft have been OK on this configuration, and I actually had them made up our VM, one or two times when we iron out some problems of UNIFIED messaging (although I hide icon "VMWare Tools"!).

  The best thing to do would be to create volumes you think you'll need and attach them directly to the virtual machine using the Microsoft iSCSI initiator, and then run the Exchange tool (I forgot his name) to test the storage for speed and capacity.

  See you soon.

• How to automate the process of deploying VM?

  Are there sources where I could find info how to automate the deployment of virtual machines? For example, if I have to deploy 100 VM, how to add script, or maybe there are tools to do?

  Thanks in advance for the answers.

  I have not yet tested, but it should work if you have VI kit installation. If its only 10-20 why not plan tasks to clone vcenter and set the frequency to be repeated every hour and stop once you have done with all of them?

  If you found this information useful, please consider awarding points to 'Correct' or 'useful '. Thank you!!!

• Automate the copy of several cells of different lines based on a non-single cell

  Hello

  I would like to automate the process for copy information in the columns of 'product', 'ref' and 'quantity' to another table in the sheet 'order' based on the text in the column "nr." I know it can be done with the help of the filter and the copy paste, but I would like to know if this can be automated, because there are many more tables in my actual document. The numbers ranging from 16/01/00 to a minimum of 16/200 then make an index for each column seems an unlikely solution?

  

  

  Thank you very much for your help.

  Kind regards

  Kim

  HI Kim,

  I see screenshots of two seemingly identical pictures. Its position, I could infer that 16/01/00 is the name of this table.

  I don't see a column named "nr."

  Please repost, with images of the two tables.
