Hi,
I'd report the similar case which I am facing.
My envrionment is;
XenServer 5.6 SP2
FreeBSD 8.3-RELEASE (amd64) -- XENHVM kernel
when booting this FreeBSD VM, its kernel cannot mount root disk.
(case 1: ad0s1a, from /etc/fstab) ==========================
ums0: <Endpoint1 Interrupt Pipe) on usbus0
ums0: 3 buttons and [Z] coordinates ID=0
Trying to mount root from ufs:/dev/ad0s1a
ROOT MOUNT ERROR:
If you have invalid mount options, reboot, and first try the following from
the loader prompt:
set ufs.root.mountfrom.options=rw
and then remove invalid mount options from /ete/fstab.
Loader variables:
vfs.root.mountfrom=ufs:/dev/ad0s1a
vfs.root.mountfrom.options=rw
Manual root filesgstem specification:
<fstype>:<device> Mount <device> using filesystem <fstype>
eg. ufs:/dev/da0s1a
eg. cd9660:/deu/acd0
This is equivalent to: mount -t cd9660 /deu/acd0 /
? List valid disk boot devices
<empty line> Abort manual input
mountroot> _
============================================================
(case 2: xbd, entered by hand just after the case 1) =======
mountroot> ufs:/dev/xbd0s1a
Trying to mount root from ufs:/dev/xbd0s1a
ROOT MOUNT ERROR:
If you have invalid mount options, reboot, and first try the following from
the loader prompt:
set ufs.root.mountfrom.options=rw
and then remove invalid mount options from /ete/fstab.
Loader variables:
vfs.root.mountfrom=ufs:/dev/ad0s1a
vfs.root.mountfrom.options=rw
Manual root filesgstem specification:

? List valid disk boot devices
<empty line> Abort manual input
mountroot> _
============================================================
HVMXEN kernel of FreeBSD 8.2-RELEASE-p6 works just fine in this
environment.
Also, I can try other "mountroot>" devices if you could tell me within
a day or two.
Thank you!!
Best Regards,
