Hi, I try to troublshoot problems with OpenBSD drivers under Xen with help of someone from Xen mialing list. He ask me to try with HVM without stubdomain. Is it possible under Qubes to create such domain?
Theoretically you can do that via modification of libvirt config using Custom libvirt config — core-admin mm_e7aa7b56-0-ge7aa7b56-dirty documentation. Specifically drop <emulator type='stubdom-linux'/> or replace it with just <emulator/>. That said, this configuration is not really tested (and not security supported), so it very well may not work at all…
