Hi list,

=> Please Cc: me when replying, as I am not subscribed. <=

I tried to install FreeBSD (201008 -CURRENT snapshot, but I don't think
it's important here) in a KVM-backed virtual machine on a headless Linux
host, following section 2.12.1 of the handbook.
	http://www.freebsd.org/doc/handbook/install-advanced.html

I've rebuilt the ISO image with the following lines in boot/loader.conf:
	console="comconsole"
	beastie_disable="YES"

The kernel boots correctly (see output below) but the output invariably
stalls after the following lines:
	Trying to mount root from ufs:/dev/md0
	/stand/sysinstal

(Yes, only one `l'.)

Any idea?
