Hello all, It seems that nova patch 756549 [0] seems to have broken us but it's not yet clear why. Aditi provided a guest XML from a failed test [1], but there are no defined USB devices despite what the libvirt error suggests. Has anyone else seen this? We'll continue to investigate. We could be hitting a libvirt bug, though I haven't found one open yet.

Hi,

We recently observed failures on master branch jobs for ppc64le. The VMs fail to boot and this is the error I observed in libvirt logs - "qemuDomainUSBAddressAddHubs:2997 : unsupported configuration: USB is disabled for this domain, but USB devices are present in the domain XML" Detailed logs - https://oplab9.parqtec.unicamp.br/pub/ppc64el/openstack/nova/96/758396/7/che... <https://oplab9.parqtec.unicamp.br/pub/ppc64el/openstack/nova/96/758396/7/check/tempest-dsvm-full-focal-py3/04fc9e7/job-output.txt>

Could you please let me know if there was any recent configuration that was done to disable USB configuration in the instance domain?

Thanks, Aditi Dukle
