Well, take it over to CentOS-virt, attach the config of the guest and I'm sure someone will spot the problem.

Nah, RHEL 5.1+ supports 32-bit domU (PAE and non PAE) on 64-bit dom0.

Actually RHEL Xen is 3.1 with the brain damaged 3.0 userland utilities.

Hi all

This is the first time I try and get Xen working, and want to install a few CentOS 5.1 32bit and FreeBSD 6.1 VM's on my CentOS 5.1 x64 server.

Trying to get the first one to install is rather trivial, and I keep on running into errors. At fist I wanted to install it fro the cdrom, so I used "virt-install --cdrom=/dev/hdc" It booted up, and I could choose my language, but then got an error saying I don't have the right driver for the cdrom install. Odd.

So, I copied the whole CD to my intranet server, to try a HTTP installation, which got much further, but fails as soon as it starts copying the files to the xvda partition.

Here's what I've done: virt-install -p --location=http://intranet/kickstart/centos/5.1/32/os/i386 --ram=512 --file=/vm/vm03.img --name=vm03

What am I doing wrong?

as far as i am aware on standard RHEL or CentOS 5 packages a 32bit domU on a 64bit dom0 is not supported and known to crash

Ok, so what do I do if I want to have a 64bit Host XEN & 32guest's? I'd prefer to use CentOS for this purpose, if possible
