Description of problem: Xen HV fails to load FC6 HVM guest with updates kernel for FC6 Version-Release number of selected component (if applicable): kernel-xen-2.6.18-1.2747.el5 xen-libs-3.0.3-8.el5 xen-3.0.3-8.el5 (If I updated to xen-3.0.3-9.el5 from nightly, same problem occurs) How reproducible: Allways happens here. Steps to Reproduce: 1. Install a FC6 HVM guest 2. Boot it, see that everything works 3. yum upgrade kernel on the FC6 guest Actual results: Kernel don't boot, stoops at the middle of the boot. New kernel is: kernel-2.6.18-1.2849.fc6 attached log of failed boot. Expected results: Kernel booting as with the previous kernel. old kernel is: kernel-2.6.18-1.2798.fc6 Additional info: I got the same problems on x86_64. In two different machines (but both of them Core 2 based).
Created attachment 142381 [details] failed boot with 2.6.18-1.2849.fc6
I can reproduce this on a i686 Intel Core Duo too.
As mentioned on at least one internal mailing list, this is due to the new auto-apic patch the FC6 updates kernel is carrying. It also breaks systems running LinuxBOIS (no DMI tables whatsoever) and a few boxes with wonky DMI tables -- see bug 215154 for additional info.
I installed a FC6, and the kernel boots. But of course this is kernel-2798.
Given that this one was for FC6 guests, and rostedt seems to have changed it to MODIFIED, going to close it out as CURRENTRELEASE. Chris Lalancette
