Yes, it is; there is a little-known tool called "kpartx" which lets you
do it.  I wrote this up for the FC5 xen wiki page: see topic "Accessing
data on a guest disk image" at

http://fedoraproject.org/wiki/FedoraXenQuickstartFC5

It's *very* useful for accessing partitions and LVM PVs/LVs from inside
Xen guest images.
