Any progress with the bug? I encouter the same problem now when upgrading from 10.04 to 12.04.3LTS. I am also using amd CPU, AMD Phenom(tm) II X4 940 to be precise.
After the upgrade, no virtual machine can be started with exactly the same error. I am considering a distribution downgrade if there is no progress with this bug. -- 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
