Hi Dominik, thanks for your reply. Of course use cases for VLAN
trunks to the guests are not difficult to find, for example when you
want to run a virtual router inside the VM, and you don't want to

define dozens or hundreds individual VLANs into the router. Anyways,
I'll take the time to write a full bug description to try and have
this supported.
Thanks.
In the meantime I've found another disturbing issue: even when I
create a vNIC profile with "no network filter" assigned, the vNIC
will only accept incoming network packets with the "correct"
destination MAC address, although the VM is also replying to ARP
queries for different ones (ARP spoofing, which is needed by many
Virtual-IP protocols). What's going on in this case? Is there a
"no-mac-spoofing" filter which is applied inadvertently, independent
of vNIC profile? Or am I missing something?
You miss nothing, oVirt configures OVN to bind the "correct" MAC
address on the VM's port.
Do you believe I should post a bug for this issue, too?
Would be nice if you would post a bug for this, too.
It would be helpful if you would give at least one concrete example of
a Virtual-IP protocol which should work inside the VM and runs into the
issue.
Thanks again,
I have to thank you for the feedback!
