Re: [Kernel-packages] [Bug 1367932] Re: qemu VM crashes the host
On 09/10/2014 06:03 PM, Joseph Salisbury wrote: id this issue occur in a previous version of Ubuntu, or is this a new issue? The problem also happened when the host was running Saucy and the OpenBSD guest was at version 5.4. Looking at the trace more closely, I noticed __secure_computing+0x73/0x260 could it be related to seccomp filtering that I enabled on QEMU (had that on with Saucy too)? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.17 kernel[0]. I will test the latest upstream eventually but I just noticed a newer BIOS/EFI was available. The changelog says Improve system stability so I'll give that a try and see if I can reproduce the issue with Ubuntu's stock kernel and this new BIOS/EFI.

Hi Chris, On 09/11/2014 01:16 PM, Chris J Arges wrote: How often does this occur? It depends: can be once a week or 3 days in a row. It almost always happened at night (during backup jobs). Have you been able to reproduce this issue without pinning your VMs to cpus? Can you still reproduce the issue after disabling seccomp filtering? Good idea, I will try to play with both settings but I will first try to reproduce it with the newer BIOS/EFI version. Another approach would be to get a full system crash using the following: https://wiki.ubuntu.com/Kernel/CrashdumpRecipe Interesting, enabling this now to capture useful dump next crash. Thanks!
