[Fedora-xen] rc3 kernel and xen
I have builds of a new dom0 kernel (2.6.38-0.rc3.git0.1.xendom0.fc15) at http://koji.fedoraproject.org/koji/taskinfo?taskID=2755802 and xen (4.1.0-0.1.rc3.fc14) at http://koji.fedoraproject.org/koji/taskinfo?taskID=2753907 You may need one or both of the following hacks Edit /etc/init.d/xenstored replacing the line XENSTORED_PID=/var/run/xenstore.pid with XENSTORED_PID=/var/run/xenstored.pid (I didn't notice they had changed the name of this file until after I tested the xen packages) Edit /etc/sysconfig/modules/xen.modules to remove xen-netback from the list of modules in the for loop then add modprobe xen-netback netback_kthread=1 to the end of the file. The xen-netback module in xen/next-2.6.38 when I built the kernel still needed some work and setting this value makes it less likely to throw up backtraces if you try to use it.

You are right, it isn't very consistent. The kernel is fc15 because it is actually a xenified version of current fc15 kernel, though it should work on other Fedora versions, and I use it on fc14 without any obvious additional problems. The xen package is fc14 because I am guessing that most people are still using fc14 and haven't switched to rawhide yet. I haven't tried the fc14 xen packages on rawhide, but I am not aware of any big differences that would cause them to break.
