Subject: [Fedora-xen] rc3 kernel and xen
To: xen@lists.fedoraproject.org
Date: Wednesday, February 2, 2011, 5:43 PM
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.

On Thu, 3 Feb 2011, Boris Derzhavets wrote:> Yes, it works now. But qemu upstream blkback performance is unacceptable slow during F14 PV DomU install :-Yes, unfortunately is true; the problem is the pthread based aio implementation in qemu-xen (I guess with "upstream qemu" you mean the qemu that comes with xen-unstable). To have decent performances we need the new qemu (what we usually refer as "upstream qemu" around here), but it is not ready yet. Our target for this is the xen 4.2 release. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
