Fix for bug https://bugzilla.redhat.com/show_bug.cgi?id=618970 The "prepare" hook is called very early in the VM statup process before device labeling, so that it can allocate ressources not managed by libvirt, such as DRBD, or for instance create missing bridges and vlan interfaces. * src/util/hooks.c src/util/hooks.h: add definitions for new hooks VIR_HOOK_QEMU_OP_PREPARE and VIR_HOOK_QEMU_OP_RELEASE * src/qemu/qemu_process.c: use them in qemuProcessStart and qemuProcessStop()
