`bug 1894804`_ documents a known device detachment issue with QEMU
|
|
``4.2.0`` as shipped by the Focal ``20.04`` Ubuntu release. This can lead
|
|
to the failure to detach devices from the underlying libvirt domain of an
|
|
instance as QEMU never emits the correct ``DEVICE_DELETED`` event to
|
|
libvirt. This in turn leaves the device attached within libvirt and
|
|
OpenStack Nova while it has been detached from the underlying QEMU process.
|
|
Subsequent attempts to detach the device will also fail as it is no longer
|
|
found within the QEMU process.
|
|
|
|
There is no known workaround within OpenStack Nova to this issue.
