I just set up an OpenBSD 6.7 kvm guest on an RHEL8.2 server and selected q35 instead of pc as a machine type. Everything seems to be working fine, except for the network interfaces (virtio interfaces). They don't work.
On the other hand, if I modify q35 by pc, everything works correctly. Do I have to change any parameter or option in OpenBSD to use q35 as a machine type, or is it simply not supported?
