O-Subject: [RHEL-AV-8.0.1 qemu-kvm PATCH 2/2] i386: Make arch_capabilities migratable
Bugzilla: 1687578
RH-Acked-by: Paolo Bonzini <pbonzini@redhat.com>
RH-Acked-by: Igor Mammedov <imammedo@redhat.com>

arch_capabilities if QEMU is able to initialize the MSR properly,
we know that the feature is safely migratable.
