@olivierlambert said in Migrating from Intel -> AMD:
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.
