restore vm on different proc

[theflakes]

We are looking to buy a AMD proc based standalone VMware server, but need to be able to restore or replicate VMs form that server to our larger production Intel based VM server farm. I know you can't vmotion between AMD and Intel, but will restores work between architectures?


thanks

Yes, VM restore as well as VM replication will work because VM essentially goes through power off/on cycle, and with that you can migrate between any processors. What will not work between processorts (for example) is suspend/move/resume (running state). But power off/on "fixes" anything. Thanks!

We plan on using the standalone AMD VM box for the Veeam virtual lab to test our backup restores. Since you can power any VM up on any CPU architecture this should not be a problem correct? Just want to make doubly sure before we commit to a purchase of this system and more Veeam licences of course. Thanks

[Gostev]

Correct, this is one of the benefits of virtualization

Also please note that you do not need more Veeam licenses, if this new box will only be used to run virtual lab VMs for verification purposes (and not actual production VMs that you are going to backup).

Thanks I figured this was the case, but have never tried it. And as always thank you for your excellent support and quick responses. This will be running less critical VMs that we need to backup so we'll be getting some more licences.

Hello,

I think I know the answer to this, but I'd like confirmation, if poss

Can I set replication to occur for a VM running on a host running intel cpu to an esxi host running amd?

I'm guessing this should work, as its not vmotion-like and should quite happily use the different cpu architecture when powering on

Thanks again

[dellock6]

Right as you said, CPU compatibility is not affected since the VM is powered off while replicated.

Yes, it should work, as Veeam B&R is storage and hardware agnostic.

Cheers guys. Thanks for confirming my thoughts

I currently have a live site using Intel Processors.
If I were to use AMD processors at the DR site and use Veeam Replication is this supported?

[apr67]

My old datacenter is AMD, new is Intel. I know I will have to shut the server down before I can run it on the Intel servers, but I was hoping I could use veeam to do the storage migrate and then use VMWare to down the server, migrate it and restart it.

Anyone got any ideas? I'm on 6.5 Veeam and moving from ESX 4.5 to 5.1

[Vitaliy S.]

Alan, you can either use replication or Quick Migration jobs to achieve what you want, no issues with that. Thanks!

[apr67]

When I do a quick migration it fails at the end because it tries to migrate the suspended VM from AMD to Intel. Is their an option to ask it to stop after the disk migration, or let it power the machine of gracefully?

[Vitaliy S.]

In this case you should be using replication jobs, not Quick Migration ones, my bad.

Hello,

Is this a possible scenario?
R905(AMD Opteron, acting as the DR host) and a R915(intel xeon, production host)
I understand I'd be able to replicate to the R905 host however I'm suspecting my guest VM's wouldnt boot per the intel to amd cpu change.
Or is this a situation where you can edit the guest vm settings and simply re-add the cpu?
Thanks!

Hello Joel, and welcome to the community!
As mentioned above, CPU compatibility is not affected since the VM is powered off while replicated.
Thanks!

Thanks for this post. The replication jobs went off without a hitch like described in this thread. I appreciate this resource makes my job much easier when I can confirm many issues before starting a task I'm unsure about.

Thanks for the kind words! We are glad to help you.
