Hi Deepak,

- yes you can perform backup of RHEL4 VM using Veeam Backup and Replication v10
- no, recovery of VMware VMs to Nutanix AHV is not supported

/Thanks!

Hi Egor

VmWare Vms can be restored to Nutanix. It is supported with the VBR Console.

From the guide:

https://helpcenter.veeam.com/docs/van/u ... tml?ver=21

In Veeam Backup & Replication console, you can restore VMs to Nutanix AHV clusters. You can restore from backups of VMware, Hyper-V, AHV VMs, from backups created by Veeam Agents and also from backups of EC2 instances and Azure VMs created by backup copy jobs.

Another list what can be restored:

Gosh, right. Sorry for misleading.
Totally mixed Full and Instant restores in my head.

While it might be possible to perform the restore, I would not be 100% certain that it would work, especially not without manual intervention. Restoring VMs across platforms requires making sure that drivers and bootloaders and other things still work. RHEL4 is very old, it was originally released in 2005 and has been end-of-life for over 4 years. It is quite different from any modern Linux distro as there has been a lot of change in the intervening decade plus since RHEL4 was released. Whether RHEL4 has the required drivers to work correctly on AHV is questionable at best. As far as I know, AHV does not even list anything older than RHEL6 in their compatibility matrix.

In other words, just because you can restore the VM to AHV does not mean it will power up and work, it might, but I don't know, and certainly it's not supported. I mean, even VMware has listed RHEL4 in it's compatibility matrix as deprecated since ESXi 6.5 GA.

That‘s true Tom.
OS Guest Level needs to be checked if it‘s supported to run on AHV.
With Linux, there is always some manual things todo. Windows was never a problem in my migration projects (mostly Xenserver to VmWare). Linux is better to build a new VM and copy the application config to the new vm.
