xenstore to release the resource allocated in backend driver lies in dom0'kernel Blktapctl thread will use qemu-dm connection instead of tapdisk-ioemu in the case of FV VM. We found the resource like memory allocated for this Guest can't be free for backend driver couldn't be closed in qemu-dm. This patch would remove the backend of tapdisk device earlier in xenstore to triger qemu-dm to notify the backend driver to release the resource allocated. I have tested this patch at the case of 1, save && restore 2, destory && shutdown 3, snapshot Signed-off-by: James ( Song Wei ) <jsong@novell.com>
