So that anyone reading this in the future, I managed to solve this
problem. I realized that since qemu needs the tun/tap driver, I might
need it for hvm-based guests too. It''s odd that xen doesn''t
complain
one bit that the driver is unavailable, though.
In any case, a simple ''modprobe tun'' solved this issue for me!
