Title:
Second DEVICE_DELETED event missing during virtio-blk disk device
detach
Status in QEMU:
Expired
Status in qemu package in Ubuntu:
Expired
Bug description:
We are in the process of moving OpenStack CI across to use 20.04 Focal
as the underlying OS and encountering the following issue in any test
attempting to detach disk devices from running QEMU instances.
We can see a single DEVICE_DELETED event raised to libvirtd for the
/machine/peripheral/virtio-disk1/virtio-backend device but we do not
see a second event for the actual disk. As a result the device is
still marked as present in libvirt but QEMU reports it as missing in
subsequent attempts to remove the device.
The following log snippets can also be found in the following pastebin
that's slightly easier to gork:
