Your "/" resides over a LVM volume. As far as there is no support for 
LVM in your running kernel, it will not find your "/" filesystem, just 
the way it happens now.

It's not "/" what resides over /dev/hdb2, but "/boot". So, even if it 
fall to /dev/hdb2, it does not find there things it needs.

The one from 2012-11-08, I'm sure you have overlooked it. In any case, I 
have sent it once again, to you directly.

Since your system actually attempts to boot, I see no way how would that 
happen without a boot loader. Judging by your screenshots, it is 
installed correctly within your DomU.

That is correct. In PV mode, the boot loader task is performed outside 
of the virtual machine. When moving to HVM, a boot loader within VM is 
needed.
