[Kernel-packages] [Bug 1208455] Re: general protection fault running apt-get inside nested kvm VM

[Kernel-packages] [Bug 1208455] Re: general protection fault running apt-get inside nested kvm VM
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.11 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.

i doubt cloud-init has any thing to do with it, other than being the thing that ran apt (which then some possibly substantial network IO and disk IO and cpu). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1208455 Title: general protection fault running apt-get inside nested kvm VM Status in “cloud-init” package in Ubuntu: New Status in “linux” package in Ubuntu: Incomplete Status in “qemu-kvm” package in Ubuntu: New Bug description: Attempting to run apt-get in a nested vm hosted in OpenStack results in a general protection fault in the kernel in the nested VM.
