Migration of VMs to a vDS

• Migration of VMs of 5.5 to 6.0 environment

  We are about to install a new environment where we want to move the existing virtual machines to with an impact as little as possible. I found a lot of similar questions already, but none for my specific problem.

  Old environment

  • vCenter Server 5.5
  • ESXi 5.5 u3 (Build 3116895)

  New environment

  • vCenter Server 6.0 u1
  • ESXi 6.0 u1

  If I understand correctly, you cross vMotion vCenter no are not supported with vCenter Server 5.5. Wouldn't be an option to upgrade the old vCenter only without touching the host to enable vMotion (if CVS is OK)?

  All strings attached to migrate offline?

  Your response is much appreciated!

  An option is simply move the vCenter 5.5 5.5 ESXi hosts the vCenter 6.0, this is the KB: VMware KB: move a managed ESX ESXi host to a vCenter Server to a different Server vCenter

  Note that if you are using vDS, there is an another knockout: KB VMware: ESX/ESXi host with vDS passing a vCenter Server to another

  Following one of the KBs I posted you can move old hosts to the new vCenter without interruption of service, but take in mind that vMotion VMs by former guests to the new, even with the hosts managed by the same vCenter, perhaps may not be possible, since you can have different processors on the old and new guests... workaround be will allow CVS on the destination cluster , but still, it all depends on the processor.

• Migrate standard network switch to VDS

  Hello

  I intend to migrate little my clusters that are running in a standard switch to DVS. Need help to automate this process.

  My scenario is:

  In a 15cluster environment are present 5 are already running in DVS
  but 10 clusters are still a standard switch so I need to migrate the
  already existing DVSwitch.

  By taking a cluster of 10node as an example.
  (1) mgmt and vmkernel are on a vswitch (ex: vswitch 0)
  [vswitch 0 - connected with 2 vmincs]

  (2) virtual machine in a vswitch portgroup (Ex: vswitch 1)
  [vswitch 1 - connected with 2 vmincs]

  On all groups, we need to migrate only machine virtual portgroup
  or vmnetwork (ex: vswitch 1) to off-network vmkernel mgmt DVs.
  My plan:
  First add all cluster hosts to DVswitch
  Remove all a redundant vmnic (ex: vmnic3) connected to the machine virtual portgroup. (Ex: vswitch) 1 and adds it to DVswitch.
  Now migrate all virtual machines connected to a standard switch to dvs. (Here I hit)
  Is it possible if VLAN 10 (standard switch) then consists of 5 virtual machines
  check the VLAN 10 DVS and portgroup network set to 10 VLAN adapter on the
  SMV (I mean can we compare VLAN ID on VSS and VDS and inspiring than us)
  need to migrate virtual machines to a DVS.)

  As below:

  

  
  If it works correctly then you have to check the State of all virtual machines (ignore power VM off) ping
  If ok then proceed to map the second network card (ex: vmnic4) VSS for VDS.

  Use the Script:

  # ESXi hosts to migrate from VSS to VDS
  $vmhost_array = @("host1","host2")
  # Adding Hosts to existing VDswitch
  $vds = Get-VDSwitch -Name "SM_UAT"
  foreach ($vmhost in $vmhost_array) {
  # Add ESXi host to VDS
  Write-Host "Adding" $vmhost "to" $vds_name
  $vds | Add-VDSwitchVMHost -VMHost $vmhost | Out-Null
  # Migrate pNICs to VDS
  Write-Host "Adding vmnic2 to" $vds
  $vmhostNetworkAdapter = Get-VMHost $vmhost |Get-VirtualSwitch -Name "vswitch1" |select -ExpandProperty Nic |select -First 1
  $vds | Add-VDSwitchPhysicalNetworkAdapter -VMHostNetworkAdapter $vmhostNetworkAdapter -Confirm:$false
  # Migrate VMs from VSS to VDS
  Write-Host "migrating vms from VSS to VDS"
  }
  
  
  
  
  
  
  
  
  
  
  

  
  

  Maybe try like this

  # ESXi hosts to migrate VSS to VDS

  $vmhost_array = get-VMHost-name 10.50.37.31

  # get existing VDswitch

  $vds = get-VDSwitch-name "Pre-production".

  foreach ($vmhost to $vmhost_array)

• Migration of VMs between Clusters

  I'm building a new cluster (esxi 4.1) and want to redesign my network configuration. Current cluster has 1 dvSwitch with 4 natachasery on each host. All the ports are on this 1 dvSwitch. My new cluster has 10 natachasery and I wanted to install 1 - dvS with 2 natachasery for management/vmotion; 1 - dvS with 4 natachasery for VM VLAN; 1 - dvS with 2 natachasery for the feet and the last 2 natachasery for future use.

  My problem is that if I set up my network the way I want on the new cluster how can I go on VMs migration to him without a break in service? Cannot vmotion between dvSwitches.

  You may only create an ESXi host for the purpose of migration. Add the new host at the same time the existing vDS and the new vDS.

  Migrate virtual machines on the host of the migration and then reallocate the VM Networking NIC for the new vDS. Then migrate comments to the new cluster host configured with your end-state configuration. You will have a very short disconnection time when you change the port used by the virtual machine, but as long as it is on the same subnet, it shouldn't be a problem.

• Migration of VMs between data warehouses

  I added a new data store to a vSphere 5.5 infrastructure and created a few scheduled tasks to migrate under tension on the virtual machines between data warehouses.

  The migration is successful, but on the source data store, I still see a lot of files for some migrated VMs, including the .vswp and vmware files - xx.log.

  This means that the scheduled task has failed?

  What have I to do to completely move virtual machines?

  Should I turn off and turn on the virtual machine?

  Concerning

  Marius

  Maybe this file are simply zombie files, generated cause an improper shutdown of the VM (take a look at the date of creation/modification of files). You can try to rename these files, if you are able to do so, these files aren't really in use. After you rename and make sure that the virtual machine works as expected, you can manually delete the files.

• Migration of VMs to other hosts in the cluster

  Hello

  I am looking for a simple script to move virtual machines on a host and move them to various other hosts in the same cluster

  I found this

  $sourcehostname = (get-VMHost 'esx01') .name

  $clusterhosts = get-Cluster "Group 1" | Get-VMHost |
  Where-Object {$_ .name-notlike '$sourcehostname'}

  $vms = get-VMHost $sourcehostname | Get - VM

  I understand gets all the virtual machines on the host and prepares to be moved inside other hosts in the specified Cluster

  I just need a hand with the Move-VM part, I need to move more than one virtual computer at once, I don't know if I need runassync inside

  Yes, vMotion VMs at the same time, you will have beed to use the parameter of the Move-VM cmdlet RunAsync.

  Note that there is a limit on the number of parallel vMotions imposed by the characteristics of your vSphere environment.

  But it's nothing to worry about in a script, vSphere will make the queue and activate for you.

  You could do something like that

  $clusterName = 'Cluster1' $srcEsxName = 'esx01' Get-VMHost -Name $srcEsxName | Get-VM | %{
    $tgtesx = Get-Cluster -Name $clusterName | Get-VMHost |    where {$_.Name -ne $srcEsxName} | Get-Random  Move-VM -VM $_ -Destination $tgtesx -RunAsync}
  

  The script runs through all the VMs on the node 'esx01.

  He selects at random one of the remaining ESXi hosts in the cluster, then vMotions the virtual machines in asynchronous mode to their new ESXi host.

  BTW if you have active DRS in that group with Automatated mode, you could just place ESXi node "esx01" in maintenance.

  DRS will migrate then all virtual machines on that node to other nodes.

  Get-VMHost -Name $srcEsxName | Set-VMHost -State Maintenance -Evacuate
  

• Interesting Situation - migration of VMs to a vCenter to a 6.0 5.0 device using VR

  I'm curious to know if anyone has used VR to move virtual machines to a vCenter 5.0 (5.0 ESXi) vCenter equipment 6(6) ESXi using VR. Note: The web client is not installed on vCenter 5.0 and two of the 3 groups that hold the candidates to migration are enabled for MRS.

  VR is supported only replying to the same version of VR (for example 5.5 to 5.5) and VR can be installed only on the corresponding version of vCenter (for example on 5.5 5.5). If unfortunately your idea won't work.

• Migration of VMs from ESX to ESXi 5.5 4.0

  Hi all

  What would be the best way to migrate virtual machines running cluster ESX 4.0 to 5.5 ESXi Cluster.

  In my view, there are two ways to do:

  1. Map (VMFS3) LUNS to the new cluster ESXi 5.5
     1. Shut down the virtual machine under the old cluster
     2. Remove inventory under the old cluster
     3. Add the VMFS3 LUN to the title of the new group
     4. Add the server to the inventory
     5. Power on virtual machines
     6. Perhaps svMotion machine virtual of VMFS3 new VMFS5 data store.
  2. Migrate the virtual via Vmware Converter Standalone Computer Cluster again.

  I think that method 1 would be the fastest, but I doubt if it is really practical, especially considering that the same data store/logic unit number will be writable by 2 different versions of ESX 4.0 and 5.5 at the same time.

  And method 2 seems the best way to me before that this will give me a possibility to start the virtual machine on the old cluster conversion failed if V2V or the destination virtual machine has problems.

  With above I have also considered possible vmotion, adding the former ESX host 4.0 under the pile of 5.5 ESXi but Xeon Intel processors are quite old and being unfit for vmotion, designed to allow CVS too, but for this I must put the new servers CPU up to the level of the old CPU and post migration of servers will have to close all VM to put all the servers again at their optimum level by disabling EVC.

  So could someone please guide which would be the best way, because we intend to migrate about 150 virtual machines. Thank you.

  between steps 1 and 2 take the new backups just in case. You have no need to have both writable for each cluster between steps 2 and 3 remove the volume from the old cluster. Also, between cold steps 4 and 5, you can migrate them to the new from the old storage.

• Need help migrating desktop VMs to ESXi 5

  Recently, I have set up my ESXi server but am having a hard time, all my images (VMware Fusion) Office move to my new server.

  I tried two approaches: VMware Converter and OVF models with success mixed in both.

  For VMWare Converter, almost half of the virtual machines I try to convert gives me this error when I select the source image and click Next: "unable to get material for the selected machine information.

  I was not able to find a common point between those who work and those who are not. Some are Linux, some are Windows 7, Server 2008, etc.

  For those who does not work with converter I tried to convert to the FVO, however, I see mixed results there too. Some work, but others when I click on deploy OVF in VSphere process completes very quickly and I noticed that the vmdk is created in my data store but 0 bytes. So, when I try to start the virtual computer fails because it cannot find an operating system.

  Someone has a better approach or may help to explain why I see this issue? VMWare Converter seems to be the way to go, I can't go beyond this error on some of my machines!

  To run the VMs Fusion in ESXi, you don't have a converter, and you don't need FVO-export.

  The vmx file is already compatible ESXi.
  The vmdk can be made compatible with ESXi
  -vmware-vdiskmanager (if you do it on the merger)
  -vmkfstools (if you do on ESXi)

  So, basically, you just download vmx and vmdk with SCP, Datastorebrowser, or whatever you prefer.

• EX 3.5 migration of VMS between data warehouses

  Hi all

  Don't know if this is location of correctr but I don't know that it will be moved required

  Scenario - I have a very small server ESX 3.5 with VM hosted on 6. We recently plugged in and set up a SAN and I'm trying to migrate servers from local storage to the San, one at a time. I wrote a script that works on the my ESX 3.5 bed test system, but does not work on my production system. I can't the biggest hard drives on the production system to copy. I run the script as a scheduled task on Saturday afternoon, after I have confirmed that my backup of vRanger connection is completed. I reason I do a "cp" oppsoed suddenly, I like the idea of being able to fall back to the original virtual machine is required. I know that most of the script is working as I can see the original virtual machine power off or not and all the files except the VMDK copied during the local storage to the San.

  I have attached the script that I use as well as the log file which follows from the weekend final run. Can someone please take a look and see what I'm doing wrong? It's driving me crazy.

  Only, we have unique ESX connected to the San, and don't use vmotion. The SAN is connected and (I hope) properly configured.

  What files are missing? Compare your source files and destination, in the case. You can also watch this http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1000936 Ko to verify if you don't a not build anything.

  Your script worked on another host, it should also work on that one.

  Good luck.

• 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

• Migration of VMS of vsphere 5.0 and 5.5. The virtual computer hardware should be upgraded?

  We have a few virtual machines to a roommate with a newer version of vsphere. Are there benefits to upgrading in addition what is listed in the link below? We have really no need for the maximum ram or cpu upgrades. I thought that now version 8 virtual machines should be fine, unless there is a major performance improvement or other reason to upgrade to 10.

  Hardware features available with the Virtual Machine compatibility settings

  You are on point with your comments. There is no need to upgrade to version 10, you if you don't need. This is why VMware is now calling VM Compatibility virtual rather than physical level. This is to remove the pressure of always trying to follow with the virtual hardware.

  By experience, I find the upgrade virtual hardware, one of the scariest parts of any upgrade project. Ive met a lot question after her that is why it is always recommended to create a snapshot prior to an update of the virtual hardware. Its the only way to restore.

• VMs migration from one to another on ESXi 5.1 data store (free license)

  I'm under ESXi in my lab (for the Cisco voice servers and a few Windows virtual machines). Virtual machines are on a datastore iSCSI hosted by a Netgear ReadyNAS Pro Business. Due to major problems with iSCSI on the ReadyNAS platform and the inability of Netgear to resolve problems (blocking NAS requiring a hard reset), I decided to buy a QNAP TS - 569 L and use it to host my ESXi data store. Now, I'm migrating my VMs from the iSCSI data store hosted on the ReadyNAS to the iSCSI data store hosted by QNAP.

  My VMs are supplied thin, and I want to preserve thin provisioning after migration. The data store Navigator ESXi can move (or copy) machines virtual data to another store, but thin-set in service virtual machines become thick-set service once they have been moved (or copied). Somebody advised Veeam to that end, I've installed and configured. Unfortunately, Veeam-error with the message that the current license does not have the migration of virtual machines from a data store to another. Just today, I learned that he must have at least the ESXi Essentials ($500) license to allow this type of migration of Veeam.

  I also tried OVFTool (the MMware command line utility), using the following syntax:

  . / ovftool - ds QNAP-iSCSI - dm = vi thin: / / vi [email protected]/CUCM-Pub: / / [email protected]

  where:

  QNAP-iSCSI is the name of the data store on the QNAP

  192.168.200.10 is the IP address of my box of ESXi that is connected to two data stores iSCSI (the one organized by the ReadyNAS and the other by the QNAP).

  CUCM-Pub is the name of the virtual machine on the ReadyNAS iSCSI data store I'm migrating to the QNAP iSCSI data store.

  However, I get the following error message:

  Error: Unexpected Option: vi: / / [email protected]/CUCM-Pub

  This is probably due to the same issue - free ESXi license does not allow this type of VM migration. So, what are my options with free ESXi license? I'm not willing to pay $500 for the license of the essential at this stage.

  Thank you!

  A few options, I can think of are:

  • export to the FVO and re - import
  • use VM explore Trilead and backup/restore virtual machines
  • Use the vmkfstools command to copy the virtual disks

• migration of the distributed switch standard, how much should be created?

  I'm migrating my VMs from standard to distributed switches.  Are there practices for distributed switches how you create?  Vmotion traffic must be on a separate dvswitch?  My plan was to a dvswitch for vMotion and the other for my VMs and mgmt of ESXi servers.  OR would they all simply in the same switch?

  Thanks in advance.

  Do not forget that each vDS need your own uplinks (physical network interfaces)... If you have enough rising, you can create several vDS, but with a small number of uplink, a better approach is to create just a single vDS and a group of ports for each type of traffic (vMotion, mgmt, VM)... and you can specify the uplink for each port group to use by using the configuration of aggregation and failover.

• Full migration to a distributed virtual switch

  Hi all

  When an ESX Server is first installed, it uses a switch vNetwork standard for COS as vswif0.

  When this server is added to the server Vcenter, the Vcenter contacted with ESX vswif0 via the standard switch.

  What is the process to move the vswif0 vDS? Is this possible via CLI?

  A new vswif to create in the vDS with a new uplink, remove the ESX the Vcenter and add it with the new ip vswif and then delete the old vswif of the standard switch.

  Is there a better way to do it?

  Kind regards

  Sharath

  It's better if you could refer to vSS to vDS migration TSB practice.

  In the doc mentioned about 2 x posible to migrate:

  1. the host migrate with some distruption to virtual machines

  2. the host migrate without distruption to virtual machines

  So, I prefer option 1, because you only have a physical nic involved.

  This option includes two steps:

  A. migrating from virtual port (console service etc.) first--so you can always manage ESX

  B. Migrate machine virtual network (Distruption on the network of the virtual computer until step B)

  Host migration with a few disruptions to virtual machines

  The process as outlined in step 3 of the chart includes two substeps:

  A. migration vmnic and virtual ports (VMkernel and Service Consoles) ports can be migrated in one step of

  vCenter Server.

  B. migration of VM networking where virtual machines are migrated from vSS Port port vDS DV groups groups.

  If all vmnic is migrated in step A, then all the virtual machines will lose network connectivity until step b. step B can follow quickly after (that's the step A

  up to the speed of the operator), but active sessions will probably drop. However, VMs may stay lit.
