<![CDATA[Migrating from Intel -> AMD]]>Hello,

We're moving from an Intel pool to an AMD one.

Turns out that even a pretty basic Debian won't boot under AMD. Kernel panics and happens so fast that even recording the screen doesn't show how it begins.

We've tried to copy a sample VM to the new host, also converting it to a template and then creating a new VM from it. Nothing works.

Is there any (known) procedure for doing this?

XCP-NG 8.2 in all the hosts (both Intel an AMD).

Thanks.

I don't know, but what I can tell is the fact I myself migration my own production from Intel to AMD without any issue, so I really wonder why your guest can't boot 🤔

Well it's weird... because happens with all Ubuntu 16 hosts too.

For this Debian in particular, even after upgrading to bullseye, still won't boot on any AMD host, only on Intel ones. Finally I just reinstalled from scratch on an AMD host and migrated the data.

So this is a guest issue then 🤔

Can you try to boot this VM with a live CD? (eg Ubuntu).

Well the guest boots perfectly from any other Intel host. I can certainly boot from a live CD though. Any action I should try once I'm there?

Are you fully up to date on 8.2 and rebooted after all updates?

Yes. And just in case, since there are no other servers there:

uptime:
12:52:12 up 21 min, 1 user, load average: 0.75, 0.22, 0.07

But still not booting.

To me, it might be a guest issue. Are all your VM in HVM mode?
