FreeBSD mount root error in openstack environment

[Venkateswara Rao Dokku]

Hi All,

I am trying to boot FreeBSD 8.4 image on openstack compute node using nova
boot command on compute node, which has Ubuntu Precise as base OS.

I am getting the following crash when I try this.

db> bt

When I did some googling, I found out that it has todo with the seabios
version that comes with the Ubuntu Precise. Please refer to the following
links for more details.

So, I updated the seabios, as mentioned in the above links. Then I am
getting the mount root issue.

Trying to mount root from ufs:/dev/md0c
ROOT MOUNT ERROR:

I am successful in getting it back with some commands from the link
http://mustaxe.blogspot.in/2007/12/dealing-with-freebsd-mountroot-prompt.html.

Here I am more interested in knowing the root cause of this. I could
able to launch the same FreeBSD in other environmetns like qemu etc.
but not in OpenStack.

Is the Seabios package upgradation causing trouble here or any other package?

Any Info on the root cause will be of great help.
