Migrating Linux Appliances From vSphere to Nutanix AHV

Migrating a Linux appliance running on ESXi over to an AHV environment can be tricky. The steps below should help migrate quite a few appliances over, but just note that some appliances won’t work in AHV at all. Check with the appliance vendor to see if they support AHV before attempting any migrations.



Steps for migrating Linux appliances to Nutanix:

1. Log into vSphere

2. Shut down the appliance

3. Right-click the appliance and select Template > Export OVF Template

4. Enter the name and notes for the appliance

5. Check the box for Advanced options

6. Select 'include MAC addresses'

6. Click OK

7. Wait for the files to finish downloading

8. Once the files have all downloaded, log into Nutanix Prism Central

9. Go to Compute & Storage > Images

10. Click on 'Add Image'

11. Select 'Image File' and click 'Add File'

12. Select each .vmdk file that was downloaded from vSphere one at a time

13. Enter an appropriate name for each disk if necessary

14. Click Next

15. Select 'Place image directly on clusters', ensure the correct cluster is selected

16. Click Save

17. Wait for the VMDK files to upload

                *Do not navigate away from the image page while the VMDKs are uploading
                *May need to upload one VMDK at a time

18. Once the VMDKs have uploaded, verify they show up in the list of images

19. Go to Compute & Storage > VMs

20. Click on 'Create VM'

21. Enter the VM name and description (should be the same info as in vSphere)

22. Enter the same amount of CPU, cores amd RAM as listed in vSphere

23. Click on 'Attach Disk'

24. Use the following disk settings:

   -Type: Disk
   -Operation: Clone from Image
   -Image: [select the VM's first VMDK]
   -Change the bus type to IDE

25. Attach any additional VMDKs that come with the VM

26. Click on 'Attach to Subnet'

27. Select the same subnet name as assigned to the VM in vSphere

28. Click Save

29. Click Next

30. Set the time zone

31. Click Next

32. Click 'Create VM'

33. Wait for the VM to finish creating

34. Power on the VM and watch the console to confirm that it comes up properly

35. Confirm that the VM is pingable

36. Have the appropriate team verify that the appliance services are functional

37. Cleanup:
   -Go to Compute & Storage > Images
   -Select the VMDKs that were just uploaded
   -Delete the VMDK images
   -Delete the VMDK images that were exported from vSphere to a folder location

For some appliances:

Once VM is powered on in Nutanix, open the console and log in
Run the command ‘ip addr’ without quotes
Check and document the altnames for eth0

Run the following command:
sudoedit /etc/system/network/static.network

Press the Input key to make changes in the file

Change the [Match] name to the current altname for eth0

Press the following keys: [Esc], then ‘:wq’ without quotes

Type in ‘sudo reboot’ without quotes

Check if the VM responds to ping when it comes back up
