I can confirm that the migration we had for Intel CPU (Haswell) is fixed

Great, thanks for testing.
I can see that for arch-capabilities, in addition to the
compatibility property, you did slightly change
the behavior by limiting it to AMD CPU (other x86 CPUs like Intel will
have the old behavior prior 10.1 so no migration issue).
Do you think it is good to make it clear in the commit log ?
Sure:
To preserve the functionality (added by 10.1) of turning off
ARCH_CAPABILITIES where Windows does not like it, use directly
the guest CPU vendor: x86_cpu_get_supported_feature_word is not
KVM-specific and therefore should not necessarily use the host
CPUID.
