I am a little confused about the usage of the ioemu statement in
"disk" statement
in the xen domU config file.  I have read examples both with and
without the ioemu
statement and i was wondering if there is a difference and when you need
to include the ioemu?

is there a difference between
disk = [ 'file:/xen/domU/sda1,sda1,w','phy:/dev/sda6,sda2,w']
and
disk = [ 'file:/xen/domU/sda1,ioemu:sda1,w','phy:/dev/sda6,ioemu:sda2,w']
?

TIA,
Tomoki
