I added the extra line with the UUID and such and was able to boot the 
domu. However it had no networking other than just localhost. So I also 
couldn't install any other software.

If I use pygrub and a dedicated /boot as ext3 should I be ok? Or is the 
grub2 being installed on the domu going to rear it's ugly head again? 
Also, how can I install grub on the domu if it won't boot?
When doing the install this way (http) it takes HOURS to complete due to 
some slow internet lines somewhere. This is a common occurrence I have 
seen with Ubuntu. Centos domu's are not blindingly fast either but I can 
usually have one installed via http virt-install in an hour or so. I am 
almost to the point to where I would ask if anyone has a working ubuntu 
10.04 64-bit PV domu and config for xen 4.0 they would mind sharing. Or 
maybe the patched pygrub files to work with ubuntu's grub2 and ext4. 
That would be super helpful. I have almost everything else done for 
this. It's always something though.
