kernel OoPs after updating to 2.6.20-1.2933.fc6xen
by Asrai khn 03 May '07

03 May '07

Hi, Today after updating kernel-xen to 2.6.20-1.2933.fc6xen on one of our host I got kernel oops and machine rebooted, when it come back again i have no other choice but to edit grub.conf and make the last working kernel ' 2.6.19-1.2911.6.5.fc6xen' the default one which working fine. DemU(s) working fine with with same kernel 2.6.20-1.2933.fc6xen, we use loopback mounted fs for domU(s) Here are the messages i found on screen before machine got rebooted (Note: machine is remote to me thousands of miles away therefore i can't check its boot screen :-S ) Now I am reluctant to update kernel-xen on our other remote hosts, never got into such issue on FC6 while updated kernel-xen. In help/suggestion will be greatly appreciated. ------ [root@xxxxx ~]# Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: Oops: 0003 [#1] Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: SMP Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: CPU: 0 Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: EIP: 0061:[<c0548ceb>] Not tainted VLI Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: EFLAGS: 00010017 (2.6.20-1.2933.fc6xen #1) Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: EIP is at evtchn_do_upcall+0x55/0x97 Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: eax: 00000010 ebx: 00000000 ecx: eaa35fe4 edx: ffffffec Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: esi: 00000001 edi: f5416000 ebp: fffffffe esp: eaa35fc4 Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: ds: 007b es: 007b ss: 0069 Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: Process find (pid: 4000, ti=eaa35000 task=ed7b12f0 task.ti=eaa35000) Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: Stack: 00000000 00000000 00000003 eaa35fac eaa35fe4 eaa35000 c0404ff2 eaa35fe4 Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: b7ff0402 00000073 00000212 bf93c920 0000007b 00000000 00000000 Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: Call Trace: Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: ======================= Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: [<c0404ff2>] hypervisor_callback+0x46/0x50 Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: Code: bd fe ff ff ff 88 d9 89 d8 c1 e0 05 d3 c5 89 04 24 eb 29 0f bc c0 03 04 24 8b 14 85 80 f0 6f c0 83 fa ff 74 12 8b 4c 24 1c f7 d2 <89> 51 28 89 c8 e8 16 db eb ff eb 05 e8 22 2e 00 00 8b 44 24 04 Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: EIP: [<c0548ceb>] evtchn_do_upcall+0x55/0x97 SS:ESP 0069:eaa35fc4 Read from remote host xxxxx.xxxx.com: Connection reset by peer Connection to xxxxx.xxxx.com closed.

Gnome and virt-manager
by Tom Horsley 30 Apr '07

30 Apr '07

OK, what is it that virt-manager needs from a Gnome session? If I point DISPLAY at a plain X session just running fvwm without the 47 gnome daemons and panels and other bling, a window flashes up quicker than the eye can see, then disappears. What the heck is it depending on from the gnome session?

Xen 3.0.4...
by Boudreau Luc 25 Apr '07

25 Apr '07

Hi ! Correct me if I'm wrong, but considering this : - FC6 ships with Xen 3.0.3 with xen-kernel version 2.6.20 - Xen 3.0.3 has a serious performance bug (see http://lists.xensource.com/archives/html/xen-devel/2006-10/msg00487.html ) - This bug is fixed in Xen 3.0.4 - Xen 3.0.4 ships with xen-kernel 2.6.16 Is it possible to install both a recent kernel version (>2.6.18) AND Xen 3.0.4 and still take advantage of the FC6 update mechanism ? Can I install the xen kernel shipped with FC6 and regularely updated through the update system, AND have a manual installation of Xen 3.0.4 ?? Luc

rhel5 hvm constantly crashes.
by Tom Horsley 24 Apr '07

24 Apr '07

I've got (so far) 5 different OS releases running as HVMs in near identical VMs, all created by virt-manager with a file-backed disk image, all x86_64, all running under x86_64 Fedora Core 6 Dom0 (Opteron system). The rhel5 VM crashes (goes into 100% cpu usage, and becomes non responsive) every few hours. I get the impression it might be related to disk I/O, since it has also crashed doing things like downloading the giant openoffice-core update rpm. All the other VMs have been up since they were installed, many happily doing big I/O like beagle-build-index, makewhatis, etc. Anyone know of a specific problem with rhel5 and qemu disks? Or any other problem that makes rhel5 hate running as a VM? The last time it crashed, I tried to do a shutdown from virt-manager and it wouldn't go away. Now it is showing up as a Zombie VM (great, VMs can get zombified, just like processes :-). Is rebooting the Dom0 the only way to clear a zombie VM?

opensuse hvm under fc6?
by Tom Horsley 24 Apr '07

24 Apr '07

I've been happily installing hvm's under fedora core 6 (x86_64), and then I got to opensuse 10.2 (also x86_64). When I try pointing virt-manager at the DVD image and installing with a big file for a virtual disk, the VM crashes almost immediately. Anyone seen this? It is just the blasphemy detector that triggers it? :-). (Though sles10 installed OK, it is just opensuse with the problem). I get the same thing when I try the "mini" ISO for a network install.
