Re: [Xen-users] help launching a Centos 5.5 Xen PV guest on an OpenSuse 11.2 Dom0 host ?

[Mark Pryor <tlviewer@xxxxxxxxx>]

Hello,

You are mixing HVM and PV type installs.
I take it for granted that you prefer PV type, so lets remove
the HVM hybrid entries.

your devices (disk=) are fine, specifying xvdi for PV.

You might be surprised to find out that the C5.5 netinstall ISO is
equivalent to using the xen aware boot files (vmlinuz, initrd) that you
D/L'd separately. So you can ditch any mention of hdc or cdrom.

The disk line with xvdc should be changed - xvdc is reserved (IIRC).

boot = 'd' is HVM only (remove)

try it again with the changes. You will get the askmethod menu by virtue of
the boot files.
