xen disk definition on dom0:
disk = [ "phy:/dev/rootvg/C5MAIL,xvda1,w",
"phy:/dev/rootvg/M_SWAP,xvda2,w",
"phy:/dev/rootvg/MAIL,xvda3,w" ]
What guest OS running xen kernel sees:
# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/xvda1 10165048 1554800 8190820 16% /
/dev/xvda3 83716784 48877780 30644700 62% /home
tmpfs 1048664 0 1048664 0% /dev/shm
However, it doesn't go so far as to let you access the first sector
of /dev/xvda
