Please unblock package libvirt
This upload fixes two bugs with qemu/kvm preventing VMs to start. The
cleanup is an upgrade issue while the caps probing is a race with
recent (as in jessie) qemu.
Please unblock libvirt.
Cheers,

+Subject: Description: qemu: Don't try to parse -help for new QEMU
+
+Since QEMU 1.2.0, we switched to QMP probing instead of parsing -help
+(and other commands, such as -cpu ?) output. However, if QMP probing
+failed, we still tried starting QEMU with various options and parsing
+the output, which was guaranteed to fail because the output changed.
+Let's just refuse parsing -help for QEMU >= 1.2.0.
