Running FreeBSD as a sun4v guest

Fri May 16 03:05:02 UTC 2008

I've tried booting the sun4v snapshot in a sun4v guest and it looks
like FreeBSD doesn't support either the virtual disk or virtual
network.  I would be interested in getting this going but the entire
sun4v port seems to have stalled.

I've noticed that the netboot is not very reliable but I'm need to
study network traces to work out whether the fault is with the
FreeBSD loader(8) or the Sun I'm using as a boot server.

FWIW, the boot looks like:
{0} ok boot net
