Thanks for any guidance, jerry

That won't help you as kernel-2.6.32.9-1.2.89.xendom0.fc12 needs at least 3.4.3 or 4.0.0 (or release candidates for them). There is a 4.0.0 rc6 source RPM at http://myoung.fedorapeople.org/dom0/src/xen-4.0.0-0.4.rc6.fc12.src.rpm though I will replace that later as rc7 has just come out.

Ok, thanks, I figured it was just me being me. I'll look for rc7 later then. Is this documented anywhere for Fedora 12/13 dom0 setup? If not, I can add this requirement to the xen and fedora wiki's, as it didn't jump out at me.
I assume 3.4.3 would only be from the xen-3.4-testing hg bits? Any pros/cons between 3.4 and 4.0? You provide the 4.0 so I suppose that is targeted to be released with the dom0 kernel, so I would be wise to go with that, right? :-)
thank you much, jerry

-rc7 is here: http://myoung.fedorapeople.org/dom0/src/xen-4.0.0-0.5.rc7.fc12.src.rpm
-rc7 worked OK for me.

Yes, 3.4.3 is from xen-3.4-testing.hg. That's where Xen 3.4.x releases are made from.
pv_ops dom0 kernels from "xen/next" and "xen/stable-2.6.32.x" branches from Jeremy's xen.git repository require new IOAPIC setup model, which is only available in Xen 3.4.3 and Xen 4.0.0 hypervisors.

I don't know if it is documented, basically you install xen xen-libs xen-hypervisor and xen-runtime and the xen enabled kernel then edit your /boot/grub/grub.conf file appropriately. Mine looks like title xen root (hd0,5) kernel /xen-4.0.0-rc7.gz module /vmlinuz-2.6.32.10-1.2.92.xendom0.fc12.x86_64 ro root=UUID=xxxxxxxxxxxxxx 3 module /initramfs-2.6.32.10-1.2.92.xendom0.fc12.x86_64.img though of course you will need to adapt this to your own situation.

I haven't actually tried 3.4.3 rc as the xen 4 rc supported these newer kernels first. I have however had problems with grub and pygrub booting for the guest in 4.0.

With pygrub I don't seem to get a menu, and the initial connection with xm create -c guest exits with the error xenconsole: Could not read tty from store: No such file or directory
pv-grub (32 bit within 64 bit) crashes shortly after the menu screen.

Hmm.. I seem to have the same problem. I'll write to xen-devel.

Xen 4.0.0-rc9-pre (latest xen-unstable) fixes this bug, it works OK for me now.
pv-grub (32 bit within 64 bit) crashes shortly after the menu screen.
If this pv-grub problem still happens I think you should open a new thread about it on xen-devel.. Keir is planning to release 4.0.0 final in around 1,5 weeks, so it would be nice to get this sorted out aswell..
