FreeBSD 9.2 won't boot without a video console under KVM

[David Tenney]

I'm trying to run a FreeBSD 9.2 64-bit installation under KVM, but am
having issues when I remove the video hardware and install a serial console
connection. The installation boots just fine when video/Cirrus hardware is
provided to the virtual machine, but once it is removed, the installation
stops at the BTX loader and causes KVM to go into Paused mode, which cannot
be returned to Running. Here is a list of adjustments that were made to
configuration files:

/etc/ttys:

ttyu0   "/usr/libexec/getty std.9600"   vt100   on secure

/boot/defaults/loader.conf:

console="comconsole"

/boot.config:

echo "-hP" > /boot.config

Any help would be great. Thanks!
