Under Xen 3.4, GPLPV should behave a little differently. The qemu
devices will be hidden by qemu itself, meaning no yellow exclamation
marks. Additionally, GPLPV will not provide a driver for CDROM devices,
and qemu will leave the CDROM device enabled, so eject etc should still
work.

I have only tested it with 3.3.1 + the patch that went into 3.4, not
with 3.4 itself, so I haven't personally verified that it works as
described.
