[Bug 667841] Re: some virtual machines hang upon boot with maverick kernel on lucid host
Thanks, Darren. Out of curiosity, can you tell me exactly which kernel and qemu versions you have installed right now? dpkg -l | grep qemu uname -a dpkg -l | grep linux-image Torsten, I am marking this 'fix released' based upon Darren's message. If you are still seeing this problem, please let me know and we'll (or you can) re-mark it confirmed. ** Changed in: kvm (Ubuntu) Status: Incomplete = Fix Released -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to kvm in ubuntu. https://bugs.launchpad.net/bugs/667841 Title: some virtual machines hang upon boot with maverick kernel on lucid host -- 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
[Bug 667841] Re: some virtual machines hang upon boot with maverick kernel on lucid host
Hi Serge, I created a new Lucid guest on a Maverick host, and now it works. As this is the first time I've tried this since commenting on the bug a few months ago, I can only assume that one of the Maverick kernel updates, or a lib-virt update in the meantime has fixed it. To be sure, I need to try with an old Lucid image (i.e. one I created under a Lucid host) but will probably have to do that next week now. Thanks for looking at this.

[Bug 667841] Re: some virtual machines hang upon boot with maverick kernel on lucid host
Could you please append to this bug a few more details, in particular: 1. contents of /proc/cpuinfo 2. the result of 'ps -auxw | grep kvm' while one of the machines is hung, so that I can see exactly what options are being used 3. More details on the guest configuration. Does the install cd run through fine, and then refuse to boot after successful install, or can you not even boot a maverick cd? thanks very much. ** Changed in: kvm (Ubuntu) Status: New = Incomplete -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to kvm in ubuntu. https://bugs.launchpad.net/bugs/667841 Title: some virtual machines hang upon boot with maverick kernel on lucid host -- 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
[Bug 667841] Re: some virtual machines hang upon boot with maverick kernel on lucid host
confirmed for me.. after upgrading host machine from Lucid to Maverick (Linux davisond-laptop 2.6.35-22-generic-pae #35-Ubuntu SMP Sat Oct 16 22:16:51 UTC 2010 i686 GNU/Linux), none of my Lucid or Hardy VM guests will boot, each hangs after grub stage 2 with Starting... on the console while the host CPU runs at 100% until the VM is Forced off. Running non-Ubuntu VM guests on a maverick host seems to be OK (tried an OpenSUSE and an IPCop image). Cloning an existing Lucid VM makes no difference, the cloned guest displays the same problem. Creating a new Lucid guest on the maverick host works (successfully installs from .iso media) but booting it causes it to hang BEFORE loading grub at all (with the single _ ) in the corner of the screen. Note that all of the above uses disk images created with qemu's raw format. Converting the image type from raw to qcow2 makes no difference (hangs at same point) and creating a new Lucid guest with a qcow2 backed image shows the same behaviour as creating a new guest with a raw image disk (hangs before grub loads). So it seems not to be image format related. This is a blocker for me, I have to revert my host machine back to Lucid as I need to run those VMs. :( I would say the importance is higher than medium. -- some virtual machines hang upon boot with maverick kernel on lucid host https://bugs.launchpad.net/bugs/667841 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to kvm in ubuntu. -- 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
[Bug 667841] Re: some virtual machines hang upon boot with maverick kernel on lucid host
Hi, Just a suggestion, but this sounds like a previous apparmor problem I had. Try killing all the virtual machines, restarting apparmour and then libvirt, then start the virtual machines one at a time. -- some virtual machines hang upon boot with maverick kernel on lucid host https://bugs.launchpad.net/bugs/667841 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to kvm in ubuntu. -- 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

Hi John, I tried restarting apparmor, and also stopping it altogether (restarting libvirt-bin each time). Had no effect on the symptoms listed above.

I can now confirm this behaviour on 2 separate host machines and many guest VMs. Just to remove the possibility of it being something odd about the setup on one of the hosts. -- some virtual machines hang upon boot with maverick kernel on lucid host https://bugs.launchpad.net/bugs/667841 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to kvm in ubuntu. -- 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
[Bug 667841] Re: some virtual machines hang upon boot with maverick kernel on lucid host
I also tried a maverick guest in the maverick host. Same problem. Looks to be a serious bug in the maverick libvirt/kvm stack somewhere. Odd that it will run non-ubuntu based kernels without any problem.

Similar problem: after updating my Lucid system to Meerkat, my virtual machines (Lucid guest) no longer boot. I get some error with respect to ATA, and then it hangs on the boot screen. -- some virtual machines hang upon boot with maverick kernel on lucid host https://bugs.launchpad.net/bugs/667841 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to kvm in ubuntu. -- 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
