Of course it is: hotplug In the case of hotplug, the hotplug monitor commands have not yet been invoked when libvirt access the file metadata, or the drive has already been unplugged, so there is still no concurrent access to the file by QEMU and libvirt.
Unless someone tries to hotplug an image that relies on a backing file already used by another image. While unlikely, it is possible. Jes
