[Bug 1021271] Re: KVM enabling virtualization on CPU0 failed
Hi Christopher, Unfortunately, I went back to Debian (which didn't have the bug) on this hardware, but now I no longer have access to this machine, so I can't do any further testing. Unless someone else watching this thread can reproduce the problem, there's no further testing/troubleshooting that can be done. Many thanks. -- 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/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-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Jason Ashworth, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu server? ISO images are available from http://cdimage.ubuntu.com/ubuntu-server/daily/current/ .

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 Server Team, which is subscribed to qemu-kvm in 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-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Which kernel are you running? (Please show uname -a output) To figure out whether this is a kernel or qemu problem, it would be useful to test kvm in a saucy chroot or container.

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.

Hi Soren. No, I do not have any other virtualisation technologies installed. This is a fresh install (installed first time with base server install only, followed by apt-get install kvm, and then a second fresh install choosing Virtual server host (or whatever the exact wording is) in the server roles selection screen at the end of the install.

Hi Jason, could you please run 'apport-collect 1021271' to have apport submit some extra debugging information?
