We've been running Debian 11 for a while, using sr-iov:
<network>
<name>sr-iov-intel-10G-1</name>
<uuid>6bdaa4c8-e720-4ea0-9a50-91cb7f2c83b1</uuid>
<forward mode='hostdev' managed='yes'>
<pf dev='eth2'/>
</forward>
</network>
and allocating vf's from the pool:
<interface type='network' trustGuestRxFilters='yes'>
<mac address='52:54:00:08:da:5b'/>
<source network='sr-iov-intel-10G-1'/>
<vlan>
<tag id='50'/>
</vlan>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03' function='0x0'/>
</interface>
After upgrading to Debian 12, when I try to start any vm which uses the
trustGuestRxFilters option, it fails to start with the message:
error: internal error: unable to execute QEMU command 'query-rx-filter':
invalid net client name: hostdev0
If I remove the option, it starts fine (but of course is broken
functionality wise as the option wasn't there just for fun :) ).
Any thoughts on what's going on here? The Debian 12 versions are:
libvirt-daemon/stable,now 9.0.0-4
qemu-system-x86/stable,now 1:7.2+dfsg-7+deb12u3
I see Debian 12 backports has version 8.1.2+ds-1~bpo12+1 of qemu, but no
newer versions of libvirt. I haven't tried the backports version to
see if that resolves the problem.
Thanks much...
