First of all, even though you can name virtual disks as "sda1" or
"xvda1", they're actually still recognized as disk, not partition.
The consequence of that is you can't use the official installer (like
Redhat's Anaconda) since they can't install to whole disk. That means
virt-install won't work either as it invokes the OS installer (like
Anaconda) in the process.

One way to do it is manual template-based installation, like (for
example) using template from jailtime.org.
I posted a mail sometime ago about converting jailtime.org Centos
image to be able to boot using pygrub, which you might find
interesting

Not really. Not if you don't use LVM on domU. If you use LVM on domU
it would add about 3% performance penalty.
The main difference would be managability. If you export the virtual
disk as "partition", mounting in on dom0 would be easier.
