Re: [Xen-users] Stable dom0 kernel > 2.6.20 ?

Hmmm, well if you want to stick with Ubuntu I guess it could be a problem.  I 
*thought* I'd heard of somebody using the Fedora kernels with Ubuntu but I'm 
not sure.

Probably need more information about how it failed in order to suggest 
anything more.

However, I'd note that you can probably "apt-get install rpm" (eek!) and then 
try using RPM to install the Fedora kernel RPMs.  I've really no idea whether 
this would work or not or if it'll do anything bad; still, it might be an 
interesting experiment.

Might be worth a try.

Actually, I wouldn't be surprised if the Ubuntu XenLinux kernel is based on 
the Fedora XenLinux patches; I'd heard that Debian's was.  Although I'm not 
sure Ubuntu's is derived directly from Debian.

Oh dear, it's all very complicated :-(

This is true.  There is code available online for folks to build and try out, 
though I'm not sure it's yet capable of running as a full dom0.

Getting a pv-ops-based kernel as the default for dom0 and domU will be a 
*huge* step in keeping kernel versions up to date.  Getting support in 
kernel.org Linux for running as dom0 would be even more awesome but even if 
that doesn't happen, we'll still be much better off.
