FYI,

I recently found out that HVM domUs running with lvm-backed storage 
detect a 0MB hard disk - this is not a domU-OS specific problem, as qemu 
itself reports 0MB
in the "bios" - thus making them unusable.

Not sure where the problem might be here, but I suspect qemu. Xen, as I 
recall, (I don't have my NetBSD/Xen box nearby) correctly detects the 
size of the logical volume.
