--- Comment #33 from John Hartley <drum@graphica.com.au> ---
(In reply to Vincenzo Maffione from comment #31)

Hi Vincenzo,

find following virsh dump of 11.3 test VM.
My 12.0 test VM is essentially the same.
Both find network interfaces with disabled (via kernel config
sys/amd64/conf/GENERIC2).

You will notice that i have 3 NICs on VM (for em0, vmx0 & re0 in FreeBSD).
I have removed VirtoIO NIC as we know that there is seperate issue with this
that Tommy T and Brian V has been dealing with.

NOTE: I am managing QEMU / KVM using "Virtual Machine Manager" UI.

Tommy T and other are now also able to reproduced the with/without netmap a=

Thanks again for assistance.
