Migration of VMS with Snapshots

• Clarification on the protection of the VMS with snapshots. SRM 5.1

  In SRM 5.1 documentation one of the limitations listed is:

  When the protection of the VMS with snapshots of the memory state, the ESXi hosts on protection and restoration sites must have compatible processors as defined in the articles of the VMware knowledge base CPU VMotion for Intel processors compatibility requirements and CPU VMotion for AMD compatibility requirements. Guests must also have the same characteristics of active BIOS. If the BIOS of the server configurations do not match, they show a compatibility error message, even if otherwise, they are identical. The two most common to check features are the No-Execute memory Protection (NX / XD) and virtualization technology (VT / AMD - V).

  
  

  
  

  You can work around this limitation by using the mode of the VCA on groups the and protected?
  

  VCA mode will mitigate this risk, but you must make sure that the two Clusters to the protégé and recovery Sites are at the SAME level CVS before take snapshots of the memory.

  At the end of the day, only a "planned actual Migration" will verify this.

  Good luck!

• Backup VMs with snapshots?

  Hello

  We have a system of vCenter 4.1 with iSCSI/FC SAN.

  To back up virtual machines, we use BackupExec 2010 with the vCenter Agent.

  The problem that we face is that we lose the snapshots when we restore the virtual machines by the Backup Exec agent.

  We also tried to use VSB with no better luck.

  The question is what are the known solutions to save our virtual machines without losing the snapshots.

  (We do not have a license of VMware Data Recovery, and we do not expect to buy it).

  Thanks for your replies.

  Good day.

  Hello, most VM backup solutions commit snapshots. I do not recommend you to use snapshots for more than a week at the top, anyway.

  I don't think that there is a software that does what you want.

  Have a read also this KB for instant best practices. Snapshot issues can be a real nightmare.

• Mail with overview of VMS with Snapshots

  Hello

  I started in a few basic to script things. The controls work very well, but I struggle to get the output of the command by mailbody.

  Here is my script:

  SE connect-VIServer - Server "vcentername" - protocol https - user "username" - password "userpassword".

  $snap = get - VM | Get-Snapshot | Select VM, SizeMB

  $smtpServer = "mymailhost".

  $smtpFrom = "sendermailadress".

  $smtpTo = "recipientmailadress".

  $messagesubject = "Snapoverview".

  $messagebody = $snap

  $smtp = new-object Net.Mail.SmtpClient ($smtpServer)

  $smtp. Send ($smtpTo, $messagesubject, $smtpFrom, $messagebody)

  I received an email and the subject is correct, but I don't have a body by mail.

  Any ideas?

  Kind regards

  Patrick

  My apologies, there is typo in the little script I've provided...

  $messagebody += ($vm. UMM Name + "' t ' + $vm. SizeMB + ' ' n ')

• Storage vMotion with snapshots

  I'm trying to implement storage vMotion in vSphere and I wanted to try to clarify some of the requirements.  3.5, VMS with snapshots could not be SVM' ed.  This has now changed in 4.1 or anyone know if it will change in the future?  Does anyone found a workaround for this limitation?

  Thank you

  Currently, there is no work around for this.  The only way is to commit snapshots, then svMotion above.  Who knows what will be the next major version to the table well!

  If you have found this helpful at all prices please points using the correct or useful!  Thank you!

• Migrate a virtual machine with snapshots.  Works?

  In the past, moving VMs between databases or host with snapshots was deadly.

  It still happens in ESX4?

  ESX4 does not throw the warning, as did ESX3.5.

  You can migrate a virtual machine with snapshots, you can just see a different question.  You try to make a vMotion in vCenter?

  What is the symptoms you see?

• vCenter 5.1 having issues with snapshot size alerts

  Hello world
  I have a problem regarding the sending of alerts by e-mail when vm snapshot size exceeds a certain size. (in fact, any size with problems)

  She doesn't send traps, ignoring what I did come in like it size and spamming my Inbox.

  Go to alerts vcenter - new alarm - monitor: VMS - monitor specific conditions or State...

  Trigger: Condition: above

  Size of Snapshot in VM (GB): WARNING: level 1

  Snapshot in VM (GB) size: alert level: 2

  Send email to: myself

  When I click on ok. I have tons of emails from vcenter which all my virtual machines exceeded the size limit of 1 GB instant! (but he doesn't based on storage views)

  Then I put the level to 10 GB makes no sense. It keeps me spamming all my virtual machines with snapshot size exceeded.

  This setting worked well with vcenter 5.0 because I upgraded to vcenter 5.1, this problem appeared. Note that I have 2 vcenters, two of them having the same problem.

  Please see the attached photos.

  VCenter version: 5.1 build: 880146 running on windows server.

  Would you kindly try to put the same trap and let me know if this is a bug or not?

  Thank you all happy new year

  It is a known issue with vCenter Server 5.1 (VM Snapshot size (GB) alarm incorrectly triggers on VMS with no snapshots (2037464)), which - according to http://www.vmware.com/support/vsphere5/doc/vsphere-vcenter-server-510b-release-notes.html - does not seem to have been resolved with the last 5. 1 b version.

• Hot migration is possible with VMWare ESXi 5.1.0 without an ESX server management

  Hot migration is possible with VMWare ESXi 5.1.0 without an ESX server management?
  I wonder for a future issue, a scenario where a system administrator must build a Win2008 + DC on local storage, server
  then, once the physical box is integrated into the class network, the physical box is connected to the classified SAN storage.
  Is it possible to hot - migrate the server Win2008 + CC local storage to SAN storage at this time, with only the
  free version of VMWare ESXi 5.1.0?

  Welcome to the community - I guess that you are looking to do this, while the virtual machine is currently running - this is not possible without a management server, also called vCenetr, but all is not lost because you would be able spend the VM local storage to the San with the VM posered using the client storage management features

• Cloning of virtual machines with snapshots

  Is it possible to take a virtual machine with snapshots, and then copy the individual vmdk files that make up a set of 5 shots manually and create a new virtual machine, so that all of the snapshots is all kept - and if it works what are the possible caviats / traps?  When you use just the cloning tool, it includes all snapshots.

  Hi TheVMinator,

  As mentioned in the kb, it is not recommended. But if you stop your virtual machine, copy the complete folder and then save the new VMX, it should work.

  The only problem that you have is a corruption of the sequence of disk. In this case, you can try to fix it or make another copy of the original VM. But you will not damage your original machine.

  Good luck.

• Best strategy for DRS with snapshots

  What happens when the DRS is enabled, but a large majority of the machines have snapshots?  Of vMotion, DRS will attempt a virtual machine with snapshots?  If the virtual machine will always be able to go back to the snapshot?  What is the best strategy for handful of situation where you have to balance the load on your servers physical but snapshots are widely used?

  Thank you

  DRS does not snapshots.

  During the stage of vMotion, only a quiescence of memory is used. But the data aren't stored, any transfer in interfaces for vMotion.

• problem with snapshots and provisioning

  Hi, I'm having a few problems creating templates of virtual machines with snapshots. Virtual machines use a provisioning, but when I take a snapshot of the virtual disk is marked as thick (it seems to be a known bug http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1020137), although it actually uses a provisioning. So, when I clone the virtual machine and mark it as a model, this new model is configured as thickness of provisioning.

  I was not able to force the new model to create as a provisioning via the Perl SDK.  Does anyone know how I could force the model to use provisioning?

  Thanks in advance.

  Hello

  In general, in order to convert the discs thick thin discs using the CloneVM_Task API, you need to set the VirtualMachineCloneSpec.location.transform as VirtualMachineRelocateTransformation.sparse. To perform the reverse operation, i.e. to convert a disc thin thick disk, set the property transform as VirtualMachineRelocateTransformation.flat

  I hope that this could be useful for you!

• Find County/VMs with 2 or more VMDK on different data warehouses

  Hello:

  I wonder how to find (and later) all VMs with 2 or more on the different data store VMDK...

  Thank you

  qwert

  Argh, you can still see that the single line in my script that I did not test, the Export-CSV cmdlet, gives you bad. The following script, I tried from the beginning to the end and gives even better output:

  $report = @()
  $allvms = Get-VM
  foreach ($vm in $allvms) {
       $clusterName = ($vm | Get-Cluster).Name
       $dstores = $vm | Get-Datastore
       foreach($ds in $dstores){
            $row = "" | select VMNAME, DATASTORE, Cluster
            $row.VMNAME = $vm.name
            $row.DATASTORE = $ds.Name
            $row.Cluster = $clusterName
            $report += $row
       }
  }
  $report | `
  Sort-Object -Property VMName,Datastore -Unique | `
  Group-Object -Property VMName | `
  Where-Object { $_.Count -gt 1 } | `
  Foreach-Object {
       foreach ($Record in $_.Group) {$Record }
  } | `
  Export-Csv "C:\VM_DS.csv" -NoTypeInformation
  

  Update: I saw that the first line was missing, so I added the first line of the script.

• Advantage of the portfolio after the migration to HSM with Oracle 11.2.0.1.0

  Hello
  
  I found this integration for Utimaco Cryptoserver guide: http://hsm.utimaco.com/solutions/db-encryption/ and now I wonder if it is necessary to keep the original portfolio after the migration of HSM with Oracle 11.2.0.1.0. As I understand it, eventually all the necessary keys are stored in HSM. Is still used portfolio in a way or is it possible to reuse maybe after you set the METHOD to FILE sqlnet.ora?
  
  Thank you

  Hi flyer007,

  If you used the Wallet before Oracle, then migrate the master key of TDE from there to an HSM is a renewal of key operation; the keys of the table (for the TDE column encryption), and tablespace (for TDE tablespace encryption) key is decrypted with the old key in the portfolio) and encrypted again with the new MK unified (in the HSM).

  Your RMAN backup files, export files Data Pump and same 'live' in the redo logs, TEMP and UNDO tablespace can be encrypted with the old MK in the wallet, that's why we NEVER delete the portfolio.

  Of course, the Oracle database automatically knows what MK he needs.

  Good luck

  Peter
