What are you trying to install? As Daniel said, in general installing from
CD-ROMs will only work in HVM.
However, there are a number of possible options:
* Fedora / RHEL (and possibly SuSE?) can be installed paravirtualised from
CD-ROM if you boot using the Xenified install kernel and initrd from the
disk.
* If you have hardware virtualisation extensions, install in HVM mode then
convert to paravirtualised by installing a Xenified kernel.
* Install from CD-ROM in Qemu, then convert to paravirtualised by installing a
Xenified kernel.
* For Debian / Ubuntu installs you can just use debootstrap to build a
filesystem in a directory tree. debootstrap runs on non-debian distros, I
think.
* There are other possibilities (e.g. I think RedHat's virt-manager can
install RH (/ SuSE guests in future?) from network shares.
Would one of these work for you? (nb. Fedora / RHEL only support PAE hosts, so
you need to have a PAE Xen installed).
It'd be kinda nice if there were a standardised spec for "how to boot an ISO
in a paravirt VM". This would require some kind of agreement between the
distributors to do things in a uniform way, but it would move us closer to
a "just works" type setup - surely a good thing. It seems relatively
unfortunate for the install procedure for each paravirt guest to be slightly
different so that the user or tools has to understand those differences.
Cheers,
Mark
