MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
RH-Author: Peter Xu <peterx@redhat.com>
RH-MergeRequest: 162: migration: Pretty failures for postcopy on unsupported memory types

RH-Commit: [24/50] 126b865f51bd4a1ae3a46411fdcd59033bfc5376 (peterx/qemu-kvm)
Once that we are there, we rename the function to migrate_compress()
to be consistent with all other capabilities.
