>How-To-Repeat:
Just install OpenSolaris, set up Xen and FreeBSD under Xen as usual and as recommended by guides available.
Using virsh (or GUI) add secondary network interface to FreeBSD domain.
Reboot guest domain, attach to it console and wait. :)
>Fix:
None known at this time. Workaround: delete secondary NIC from domain definition.
