I saw a similar crash when running the prepare script with a Saucy64 host, a Saucy32 1rst and Saucy32 2nd level guest. The 1rst level guest cpu set to core2duo and I also had to replace the qemu-system-x86_64 by qemu (which maps to the same arch). Otherwise the 2nd level guest was not started at all.
That would on one run give a double-fault as you had, but the second attempt did succeed. Though both runs had a lot of NMI (reason 21 and 31) messages in them. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1208455 Title: general protection fault running apt-get inside double nested kvm VM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1208455/+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
