Re: [Fedora-xen] Re: [Xen-devel] Re: Errors when build 2.6.31-rc8

Pasi,

I was trying to load the most recent 2.6.31-rc8 under Xen 3.4.1 ( via src.rpm) on F12
rawhide and got stack trace. Jeremy is saying that rc8 works ok under Xen Unstable.
But, Libvirt 0.7.0-6 would obviously have dependencies  on xen-3.4.1 packages.
If i will port Xen 3.5 directly to F12 (F11) it might work with rc8, however Libvirt 0.7.0-6 will be most probably lost again. Libvirt 0.7.0-6 has been built for 3.4.1 Hypervisor ( in my understanding) . That's why i wrote if Xen 3.5 can load rc8, the easiest way to fix
issue is to backport required Xen 3.5 CSs to xen-3.4.1-X(?).src.rpm  and get it resolved before F12 November's release.

Boris

Uhm.. sorry I'm a bit confused. If I understood correctly you have a
call trace on your pv_ops dom0 kernel?

Does that only happen with Xen 3.4.1 or what's the problem?
