https://bugzilla.novell.com/show_bug.cgi?id=704537 https://bugzilla.novell.com/show_bug.cgi?id=704537#c1 --- Comment #1 from G Venk 2011-09-30 01:39:36 UTC --- Just updating the report to indicate that the bug persists in the latest software builds as indicate below. Also, it is not necessary to connect to the guest for it to crash. Just starting the VMs as part of the host boot and not doing anything with it will make the VMs crash within a minute or two. Subsequent starts of the VM show absolutely no crash problem and has been tested with up-times of weeks. The last log message when it crashes is always qemu-kvm: virtio: trying to map MMIO memory This message does not appear otherwise. Current software versions: Kernel 2.6.37.6-0.7-desktop KVM kvm-0.15.0-119.3.x86_64 libvirt libvirt-0.9.6-167.1.x86_64 spice-client spice-client-0.8.2-4.1.x86_64 soice server libspice-server1-0.8.2-4.1.x86_64 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Apparently Ubuntu and Red Hat are still investigating the root causes. As soon as things are more clear we'll look into the issue again. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

We've updated the versions of the related packages, and things should be substantially different.

https://bugzilla.novell.com/show_bug.cgi?id=704537 https://bugzilla.novell.com/show_bug.cgi?id=704537#c6 --- Comment #6 from G Venk 2012-05-05 03:02:58 UTC --- Just wanted to update that the bug was in the para-virtualized disk driver for Windows as I suspected above and has been found and fixed by Redhat in their distribution. It turns out that Avast anti-virus is the one that triggers the bug. It explains why I saw it in alternate reboots. Avast does more extensive checks at startup based on when it last did the checks so the second reboot will skip those checks and avoid the bug. https://bugzilla.redhat.com/show_bug.cgi?id=771390 Can anyone confirm whether this fix (and future versions of para-virtualization drivers for Windows guests) will be available for OpenSuse? This is important since without support for these drivers, support for Window guests with para-virtualization is pretty much dead and so OpenSuse can no longer be considered a candidate as an open source linux host for KVM based virtualization. Would appreciate if someone with information or ability to find out can respond as to where OpenSuse stands regarding these drivers.

From the RedHat bug, it sounds like it is an issue with how avast antivirus is making requests larger than what the virtio block driver is expecting. If you have some good steps on how to reproduce, that would be helpful.

Please install VMDP-WIN-2.0 in the winxp and win7 vms: http://download.novell.com/Download?buildid=31EiPNl27zQ~ For the winxp vm, copy the attached vrtioblk.sys file into \windows\system32\drivers. Reboot the vms and see if the issue still happens or not in either vm and report.

The VMDP-WIN-2.0 is commercial software with it's own EULA tied to SuSE commercial subscription, not part of OpenSuse distribution and so I will not be able to install it to try. Can you let me know if this set of drivers is available as part of any OpenSuse distribution version under a non-commercial license? Is there a plan to update the drivers provided with the OpenSuse distributions (which are really old)? If not, then I am afraid I will not be able to help you with the debugging/testing. Whatever Novell decides to do is fine with me but I can only help maintain the non-commercial OpenSuse distribution. Hope you understand. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Since vmdp, as noted above is a commercial package, the open source drivers from comment 13 can be used instead.
