MIGRATE A VM FROM
XENSERVER to NUTANIX ACROPOLIS
1. Create
a Container called “XEN” on the Nutanix Appliance Prism console
2. In
the Prism menu, select the “Settings” cog icon on top right side of menu and
select “Filesystem Whitelists”
3. Add
the XenServer Management IP and subnet eg (x.x.x.x/x.x.x.0). I added the
storage IP and subnet also but this may not be required.
4. On
the XenServer that you are migrating from, add a new SR (NFS) and point it to
the nutanix / Xen container that you created:
5. Shut
down the VM to be migrated in XenCenter:
6. Right
Click VM after shut down. Export and run through wizard to export to storage on
the XenServer Console host
7. Ok
through XenServer migration prompts until “Configure networkin2g options for
the transfer VM” window and select “Management Bond” in the drop down “Network”
settings. Choose auto allocate IP or
specific a static IP to be used.
8. Untick
Verify Export on Completion
9. In
XenServer Select “View” then select
“Hidden Objects”. Check the Event Tab log
to make sure that the Transfer VM has been created. Go the console of the Transfer VM and make
sure that the VM has picked up a DHCP address so that it can export the VM.
10. In
XenServer, click on “Notifications” and “Events” log. Click on the Down arrow next to the export VM
event and make sure that the status is set to “transferring virtual disk”
11. Wait
until this job is completed. This can
take a few hours.
12. Detach
the virtual disk for the migrated VM in the XenServer console. You will see the warning “Detaching this
virtual disk will remove the association between it and the VM while preserving
the disk and its data. Would you like to
continue?”
13. Go
to the SR node in XenServer where the disk is located and select the disk that
you detached from the VM. Right Click
and “Move” the Disk to the Nutanix SR that you mounted earlier
14. Check
the XenServer Events tab and wait until the move has completed. This can take a couple of hours depending on
the size of VM.
15. Once
completed, mark the VM in XenServer as “Do not switch on”
16. Use
WinSCP to connect to a CVM IP and
username password
17. Or
username admin and configured password
18. Double
click on the XEN container and copy the file name and container name into the
command eg:
19. image.create
VMDRIVE source_url=nfs://127.0.0.1/XEN/51037c42-6da5-cb48-964b-6c226b9ae643/de7bc643-5e97-46b3-bded-a4bfee2ba5a0.vhd
container=XEN image_type=kDiskImage wait=true
20. Putty
to admin console
21. Logon
with appropriate username and password
22. Logon
and run: Acli
23. Copy
and paste the above command and wait and hour or so until the conversion has
completed:
24. This
operation will remain at “Pending” status until complete. Do not try to run the command again or kill
the process. It is not possible to kill
the task.
25. You
will also notice an image creation process queued in the Prism Console
