My configuration is:

gentoo amd64-2007.0
Xen 3.1
kernel 2.6.20-xen-r6
VM PV and HVM

The test on the vm finishes with success but all other vm crash o_O
Under I/O high workload seem that xen have some problem... Any ideas?

I have had same issue when I was untarring portage-tree on new
installation of gentoo (HVM).
Could this problem be related to LVM mapper or RAID software?
