qemu 2.0 added the ability to commit the active layer, but slightly differently than what libvirt had been anticipating in its implementation of the virDomainBlockCommit call. As a result, if you attempt to do a 'virsh blockcommit $dom vda', qemu gets into a state where it is waiting on libvirt to end the job, while libvirt is waiting on qemu to end the job, and the guest is effectively hung with regards to further commands for that block device.
This patch should be committed before the 1.2.5 release, while I continue to polish my full series for active commit support for inclusion after the release.
Agreed.
