The patch removing "x-" prefix from post-copy migration capability was
pushed to QEMU yesterday. I don't think such a trivial change on its own
requires reposting, I'd rather wait for other feedback. The current
version of this series can be found in my staging repository at
https://gitlab.com/jirkade/libvirt/commits/post-copy-migration

For Peter:

git clone -b post-copy-migration https://gitlab.com/jirkade/libvirt.git
