How about replace this:

> # Best is to use hda for your HDD, and hdc for your CDROM

with this:

# hvmloader only recognizes certain device names for the virtual disk
# drives, so it is best to use hda for your hard disk, and hdc for your
# CDROM.
# Also, host device names relative to /dev are not always recognized as
# such, so it is best to use /dev/ explicitly in the host device name.

> disk=[ 'phy:/dev/mapper/vg0-mylvmhda,hda,w','file:/path/to/iso/to/boot.iso,hdc:cdrom,r' ]

and add this:

# or, to let the guest read from the host's /dev/sr0 cdrom directly:
disk = [ 'phy:/dev/mapper/vg0-mylvmhda,hda,w','phy:/dev/sr0,hdc:cdrom,r' ]

I dislike documentation that is vague; I would prefer to get upstream to
make a definitive statement such as "hvmloader can use hda through hdd
or sda through sdh as a hard disk or cdrom drive; hd? will use IDE
emulation and sd? will emulate a SCSI drive."

Until we get upstream to clarify this, what you have above (perhaps
with my changes) will have to do.  :-P

Thanks very much.
