[ovirt-users] Re: Unable to start VMs after upgrade from 4.4.9 to 4.4.10

Good morning, please note that I got a bit further with my investigation. It might be a bug in the VDSM as I see the following while powering down the problematic VM: MainProcess|libvirt/events::ERROR::2022-03-24 20:43:48,740::supervdsm_server::99::SuperVdsm.ServerCallback::(wrapper) Error in unsetPortMirroring Traceback (most recent call last):   File "/usr/lib/python3.6/site-packages/vdsm/supervdsm_server.py", line 97, in wrapper     res = func(*args, **kwargs)   File "/usr/lib/python3.6/site-packages/vdsm/network/tc/__init__.py", line 104, in unsetPortMirroring     acts = _delTarget(network, QDISC_INGRESS, target)   File "/usr/lib/python3.6/site-packages/vdsm/network/tc/__init__.py", line 50, in _delTarget     fs = list(filters(network, parent))   File "/usr/lib/python3.6/site-packages/vdsm/network/tc/__init__.py", line 174, in filters     for filt in _filters(dev, parent=parent, out=out):   File "/usr/lib/python3.6/site-packages/vdsm/network/tc/__init__.py", line 199, in _iterate     yield module.parse(tokens)   File "/usr/lib/python3.6/site-packages/vdsm/network/tc/filter.py", line 99, in parse     data[data['kind']] = _filter_cls_parser(tokens)   File "/usr/lib/python3.6/site-packages/vdsm/network/tc/filter.py", line 119, in _parse_u32     _parser.consume(tokens, '???')   File "/usr/lib/python3.6/site-packages/vdsm/network/tc/_parser.py", line 36, in consume     raise TCParseError('Found %s, expected %s' % (found, expected)) vdsm.network.tc._parser.TCParseError: Found not_in_hw, expected ('???',) I already manage to find out that this is related to the specific vNIC configuration which is using the port mirror flag. My plan is remove and add the port mirror from the vNIC as the first step. After that I will recreate the vNIC. Any recommendations? Best regards Christoph Am 24.03.22 um 12:31 schrieb Christoph Timm:
