To recreate: 1) Follow instructions on internal wiki (page "InformationInfrastructure/IS/CanonicalOpenstack") to create a keypair.
2) Create an guest instance: $ keyname="${USER}_lcy01" $ image=$(euca-describe-images|grep saucy|head -1|awk '{print $2}') $ euca-run-instances -k $keyname -t m1.medium $image 3) Identify IP address and instance name ("i-0000XXXX"): $ euca-describe-instances 4) ssh into system 5) Install required packages: $ sudo apt-get -y install genisoimage linux-image-extra-virtual bzr qemu-kvm qemu-utils 6) Setup groups $ usermod -G kvm -a ubuntu 7) Logout and back in again to pick up kvm group membership. 8) Checkout bzr branch: $ bzr branch lp:auto-package-testing $ cd auto-package-testing 9) Apply patch on this bug to disable byobu and enable kvm logging (to /tmp/kvm.log) 10) Run the following: bin/prepare-testbed -r saucy -d i386 11) tail -f /tmp/kvm.log and wait for massive cpu usage and kernel spew in /tmp/kvm.log. 12) Cleanup: $ euca-terminate-instances i-0000XXXX -- 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 double nested kvm VM Status in “linux” package in Ubuntu: In Progress Status in “qemu-kvm” package in Ubuntu: New Status in “linux” source package in Saucy: In Progress Status in “qemu-kvm” source package in Saucy: 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.
