Here is another kernel (2.6.38-0.rc6.git0.1.xendom0.fc15) at http://koji.fedoraproject.org/koji/taskinfo?taskID=2861178 . This comes with a warning because for me the dom0 system reboots when a domU guest is shutdown. Michael Young

Hi I tried the kernel, but it was unusable. 24.02.2011 02:23, M A Young wrote:

I had kernel crashes even without Xen hypervisor: Without Xen: crash. Under Xen, 1500M memory: crash Under Xen, 3000M memory: crash Under Xen with nomodeset: crash. So booting up goes about OK, until Fedora tries to start Xorg.

I just had a chance to test this, along with the xen-4.1.0-0.1.rc6.fc14.x86_64 Xen packages. Two notable things have been fixed by the Xen folks: xl now plays nicely with the vif-route script (see /etc/xen/xl.conf). xl is less picky about where the "-c" argument to create goes. Both of these issues were previously discussed on this list and the xen-devel list. I'm still having trouble with power management, as noted at: http://lists.fedoraproject.org/pipermail/xen/2011-January/005328.html Other than that, my first impression of 2.6.38-0.rc6.git6.1.xendom0.fc15 is good. I was able to load a PV OpenWrt guest using the QEMU-based network backend. -- Mike :wq

My computer doesn't power down either. This has been seen all the time. Under Xen hypervisor: power down doesn't work. Without hypervisor power down works with the same kernel. Regards, Marko

Do you see the same behaviour with 2.6.32.x based dom0 kernel aswell? -- Pasi
