Detailed bug description:
This update allows libvirt to expose new CPU features added by microcode
updates to guests. On amd64 and i386, new CPU models that match the updated
microcode features were added with an -IBRS suffix. Certain environments
will require guests to be switched manually to the new CPU models after
microcode updates have been applied to the host.
