Migration cold with snapshots

• Make pseudo migration cold with free ESXi 3.5 VI Client?

  Even if I used VMware products for years (Workstation, Server), I'm still pretty new to ESXi.  I started using the free ESXi with the idea to be able to live migration between ESXi hosts.  However, I then discovered that you can't do vMotion with free stuff.  No biggie; I probably don't need it anyway.  All I really need is the ability to move virtual machines between ESXi hosts.  I'd settle for migration cold.  However, after reading the article on migration in the basic manual Admin, it seems I have to use Virtual Center to be able to do.  Am I wrong?  And I'll take it, Virtual Center is not a free download.

  But do I really need to Virtual Center to move virtual machines between ESXi hosts?  It seems to me that I could just use VI client to do a migration of the nickname 'cold '.  Is there something wrong with the following scenario:

  1. all VM files are kept on a central NFS server.

  2. I stopped the VM on HostA.

  3. Add the virtual machine to host b inventory.

  4 remove the virtual machine from the inventory of the HostA.

  5. I turn the VMS on host b.

  Of course, this is not automatic and not stupid, but it's free so I can't complain.

  Thanks in advance for any information or advice you can give me.

  No, and that's all a 'cold' vmotion is anyway...

  Take a look at this http://communities.vmware.com/docs/DOC-9400 (ghettoQuickMigrate.sh) (free vmotion)

• What is 'Migration to cold with resettlement of the file'?

  Hello

  I just read http://kb.vmware.com/kb/1005241 on the migration of virtual machines with attached RDM. The document states that the following is true when you are migrating cold with moving file.

  When you are migrating cold a VM with RDM attached to it, the content of the raw LUN mapped by ROW is copied into a new hard to destination file, effectively converting or cloning a raw LUN in a virtual disk. This also applies when the virtual machine is not moving between ESX hosts. In this process, your raw LUN origin is left intact. However, the virtual machine is more reads or writes to it. Instead, the newly created virtual disk is used.
  I just tested this and migrated cold a VM with vRDM attached to another data store. However, the vRDM has not converted to a virtual drive, but remained as a vRDM. Is the "Cold Migration with file transfer" something different than right-clicking on the VMS in vCenter, choose "migrate" then 'Datastore change' or 'change of host and data store '?
  Thank you

  Hello

  Glad to hear that it worked for you, yes the document isn't very desciptive processes to do it, the only reason that I know how to do it is previous experience.

• Migration of VMS with Snapshots

  I'm at the stage of planning an ESX 3.5/VC 2.5 upgrade to vSphere.  This will be a 'rotating' upgrade, so many migrations VM will take place.  We are all local storage, so the migration will be in data warehouses.

  Unfortunately my shop uses snapshots very strongly.  I am aware of the problems created when popular VM migration with snapshots in data warehouses.  My question is, using VMware Converter makes this possible?  If I can avoid having to delete all snapshots, it would be a huge bonus.  I can't seem to find a definitive answer on whether or not, the converter can handle this.

  Thank you.

  Hi chester78,

  You are right, you cannot migrate a virtual machine without deleting the existing snapshots.

  The alternative you are thinking to use vCenter Converter to migrate virtual machines, it is a good choice to avoid deleting snapshots and all the time this action takes.  VCenter Converter will migrate virtual machines in the current state.

  In the shots, I recommend you read this VMware KB on best practices for snapshots of virtual machines:

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=1025279

  Best wishes / Saludos

• 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?

• Migration cold - how many simultaneous servers

  We have a customer moving servers from one host to another host in the same ms. We do a migration cold because there are some limitations to this customer and no SAN/storage network so all local drives on the host server. Although we can now do vMotion without storage applications SAN/network has some limitations too and client wants to move which is supported by the seller and do not go by what VMWare can support. Our question is when we make cold migration using vCenter doing this option, stop comments right click migrate host and data store servers how can we move simultaneously at once a single server at a time, or we can do more than one. Any help would be appreciated. I am less familiar with this side of vmware, so feel free to ask for more information in case if I did not understand our scenario.

  VCenter is 5.5

  Esxi host on source version is 5.1 and destination is 5.5.

  There is a little math to do, but you can see the rates here: https://pubs.vmware.com/vsphere-55/index.jsp?topic=%2Fcom.vmware.vsphere.vcenterhost.doc%2FGUID-25EA5833-03B5-4EDD-A167-87578B8009B3.html

• 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!

• Migration cold trip via lan or san?

  Assuming that VM moves to the data store CF on the same host or different host with the same access to FC storage shared... migration cold trip via lan or FC san?

  If you change data on the same host warehouses, data are transferred through HBA.  If changing hosts but vm location does not change, it changes just the host on which the virtual computer is marked (e) on.  If you change hosts and data warehouses, it goes on network.

• MIGRATE A VM SNAPSHOT (within a cluster)

  I need to reboot an ESX Server (for an update of the firmware) and I am trying to vmotion (hot migration) a snapshot of a virtual computer that has various revisions (not storage vmotion). The snapshot is stored on the VMFS on SAN not locally. When am I going to migrate the virtual machine, I get the warning message:

  "Go back to the snapshot would generate an error (warnings) on the destination host.

  Can someone tell me what this means?

  I think that this warning is ok to ignore the VM has all of its files on the shared storage, and storage is accessible to all ESX hosts. Can anyone confirm this?

  If you try a virtual machine with snapshots of a host running VMotion to another, you will receive the following warning: "Instantaneous restitution would generate error (warnings) on the destination host". This simply warns that if you changed the default location for files of the virtual machine (such as snapshot or vswp files), the VM will crash when the migration is complete. This is true if the destination host is unable to access the storage as well as the files on the source host.

  So if your virtual machine has been in storage shared and configured so that the snapshot files are on the local storage, then you'd have a problem if you VMotioned the machine virtual to another host. If your virtual machine has all of its files on the shared storage, and storage is accessible to all ESX hosts, then you are in good shape. VMware recommends that you make all the snapshots before VMs fast vMotioning. But if you do not, it will work fine.

• Using Migration Assistant with no display

  I got my MacBook mid-2010 (2.4 GHz, 4 GB RAM, OS X El Capitan) for 2 years.

  It splits into two somewhere within 2 years.

  The MacBook was still usable, but it had to be on a desk. The screen was completely separate from the base. It still worked.

  I woke up a few days ago to find that someone had cut the display cable holding the MacBook set and turn on the screen.

  I bought an early-2011 13 "MacBook Pro to replace the dead MacBook. (Yes, I buy old Mac because the news is so expensive).

  Old Mac has been saved semi regularly, so I have an old backup to use for the new Mac. The problem is that just before the death of the former Mac, I downloaded a bunch of stuff that has not been saved. I really want the files that have not been backed up on my new MBP.

  Can I use Migration Wizard with an Ethernet cable and transfer of data from one, or Migration Assistant must be running on old Mac as well?

  I tried to connect (I'm sure that the computer is still running, it doesn't simply have a display) on the old Mac, plug the backup drive and I hope to do a backup hourly, but Time Machine did not only.

  Any suggestions would be GREATLY appreciated.

  If you use Ethernet or a wireless network to transfer data, Yes. If you can not download the files and file-sharing has not been activated on the old Mac, you must either get fixed display or put its internal drive in a closed Chamber.

• Storage migration fails with the error: could not complete the network copy to path to the file

  Hello

  I have two hosts ESXi 5.5 with local storage and VMware vCenter device which manage them. Everything worked well until that time.

  Now when I try to make the host migration and storage, processing or power off the virtual machine, I get the error message:

  Could not complete the network for file /vmfs/volumes/.../path/to/file.vmdk copy

  The situation is the same when I try to deploy VM on ESXi-2 model that is on ESXi-1.

  All with the network configuration is correct. I have ping between the hosts on ESXi and ESXi and vCenter. No firewall hosts ESXi and vcenter. No physical firewall between hosts.

  The network latency is less than 1 ms. No packet loss.

  I read this VMware KB article: Storage migration fails with the error: could not complete network file copy and I tried solutions explained here, but the results are the same.

  You have ideas where the problem may be?

  Hello guys,.

  I finally found the problem.

  ESXi servers are configured with MTU 9000, but the switch where the hosts are connected was a bug documented with frames. I found the problem after finding this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003734

  I run the command of ESXi-1:

  vmkping - d-s 8972 192.168.10.12 where 192.168.10.12 is the ip address of ESXi-2

  The result was:

  3 packets transmitted, 0 packets received, 100% packet loss

  as a workaround, I reduce the MTU to 1500, then I patched the problematic switch.

• 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.

• 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.

• 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!
