Only recently using HVM, not paravirtualization

I would like to vouch for openbsd working great as a guest, but my
guest has crashed a dozen times. However I think this is due to the
debian linux dom0 having broken sata code for the controller in use.
dom0's dmesg is filled with debug statements from sata related places
in the kernel that should never be printed. We're in a messy
de-centralized linux development world trying to get a stable dom0
patched together. It sucks.

The paravirtualization port appears dead to me. I've tried to keep up
on it, but the guy's blog no longer mentions it, his repository is
often down, and when it is up the commits do not appear to be very
frequent. Also his blog hasn't mentioned it in a year or more.
