I have a 3.0.3 64-bit test-setup for a few month with not much load and
a filesystem on LVM. I did not see any problems.

For me it worked out of the box. Maybe the problems were corrected
later? I use tools like xen-create-image and xm without problems.

BTW: I had problems with the 64bit xen-vserver kernel package, but not
with the xen-only kernel package.
