Hello,
I am migrating a suspended x86-64 guest (disk & state) across
different x86-64 hosts with small differences in the available CPU
instructions and when I try to resume the guest on the different host
libvirt reports an error like this "CPU feature XXX not found" and
fails. My question is, is there a way to limit the instructions that
are used on the "origin" host when creating the guest to avoid this
error? I am pretty sure there is a set of basic instructions that are
available across all hosts which could be used for this purpose.
Thank you!
You want to take a look at specifying the guest CPU:
