Tried to run an HVM instance, here's the error report I got.

# /usr/pkg/sbin/xm create -c /usr/pkg/share/examples/xen/hvm-netbsd
Using config file "/usr/pkg/share/examples/xen/hvm-netbsd".
Started domain hvm-netbsd
Unexpected error: exceptions.OSError

Any feedback helping me troubleshoot this would be appreciate this. Thanks.
