Comment 3 for bug 1832248

We have a similar issue in operation q35/qemu-4.0/libvirt-5.4.0,
but for interface attachment, not able to reproduce easily for now.
Same behavior, attachment seems ok from libvirt/nova,
then libvirt receive "DEVICE_DELETED" event from qemu.

This result in guest persistent config still containing interface
(virsh dumpxml instance --inactive) but no more on active one.

Is the tempest test was always failling in an devstack isolated run (not in CI)?
Because I'm not able to reproduce the issue on master using ubuntu focal (qemu-4.2.3/libvirt-6.0)
and disabling the workaround fix with this change:
/usr/local/lib/python3.8/dist-packages/os_brick/initiator/linuxscsi.py:
602 #if use_multipath:
603 if True:
