[Bug 1379340] Re: qemu-kvm guest panic for AMD smp trusty guests
I'm able to reproduce this and currently it looks like its fixed in 3.18-rc1. The main things that need to be enabled are 'cpu mode=host- passthrough' and 1 CPU. If 'cpu mode=host-model' is enabled and 1 CPU things work fine. The differences in cpu features were: npt nrip_save tsc_adjust I've also tried this on Intel platforms and was unable to reproduce, I was able to reproduce this on an AMD Opteron 6276 processor. Working on finding the patch to backport. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu in Ubuntu. https://bugs.launchpad.net/bugs/1379340 Title: qemu-kvm guest panic for AMD smp trusty guests To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1379340/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Not keen on providing apport info as this is a production system with multiple tenants and we have no agreement with Canonical.

Hi, could you provide the exact command used to launch qemu to produce this error? If using libvirt, you can find this in /var/log/libvirt/qemu/name.log if using virsh for example.

[Bug 1379340] Re: qemu-kvm guest panic for AMD smp trusty guests
Thanks for reporting this bug. Would it be possible for you to test with the daily upstream kernel builds, to rule out any temporary kernel regressions? Instructions for that are here: https://wiki.ubuntu.com/Kernel/MainlineBuilds I'll also build an uptodate daily qemu build so we can test whether it has been fixed there. I don't currently have any amd box available (but should in a few weeks) to try and reproduce - and then hopefully bisect. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu in Ubuntu. https://bugs.launchpad.net/bugs/1379340 Title: qemu-kvm guest panic for AMD smp trusty guests To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1379340/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
