Thanks for the help but alas it does not work this time either. I have installed and tried both linux-generic-lts-quantal and linux- generic-lts-raring:
$ sudo wajig install linux-generic-lts-* Result with quantal: hong@vhost01:~$ uname -a Linux vhost01 3.5.0-42-generic #65~precise1-Ubuntu SMP Wed Oct 2 20:57:18 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux hong@vhost01:~$ sudo kvm failed to initialize KVM: Device or resource busy Back to tcg accelerator.

With further Googling I stumled upon a post: https://bbs.archlinux.org/viewtopic.php?id=148163 which suggests a BIOS upgrade might work. But since kvm worked perfectly under 10.04LTS, it should be software related and a BIOS upgrade would be a last resort as a workaround rather than a solution. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1021271 Title: KVM "enabling virtualization on CPU0 failed" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1021271/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
