When a Xen HVM guest is started with multiple disks in addition to a
cdrom, e.g.
disk = [ 'phy:/dev/VG0/boot,xvda,w',
'phy:/dev/VG0/swap,xvdb,w',
'phy:/dev/VG0/root,xvdc,w',
'phy:/dev/cdrom,xvdd:cdrom,r',
]
how does one correctly specify booting from the cdrom?

XEN: How to CD-boot fully-virtualized DomU's after initial
installation
http://www.novell.com/support/kb/doc.php?id=3156432
"The drive numeration for fully virtual booting follows
the traditional DOS drive enumeration;
that is, hard disk start at "C" and continue up,
followed by CD-ROM devices."
suggests
boot='f'
But, as these params are (?) passed to qemu, checking qemu's man page,
-boot
[order=drives][,once=drives][,menu=on|off][,splash=sp_name][,splash-time=sp_time]
Specify boot order drives as a string of drive letters. Valid
drive letters depend on the target
achitecture. The x86 PC uses: a, b (floppy 1 and 2), c (first
hard disk), d (first CD-ROM), n-p
(Etherboot from network adapter 1-4), hard disk boot is the
default. To apply a particular boot
order only on the first startup, specify it via once.
suggests,
boot='d'
Which is correct?
