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
