I ran into the same problem after upgrading from Lucid to Maverick. The problem is that vmbuilder isn't changing the disk file format from `raw' to `cow2' when moving the image from /tmp to the install location. To get the VM to boot just fire up virsh, edit [vm], and change "<driver name='qemu' type='raw/>" to "<driver name='qemu' type='qcow2'/>".
If you're not familiar with vi, then run virsh like `EDITOR=nano virsh ....' -- new virtual machines do not boot https://bugs.launchpad.net/bugs/634488 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to vm-builder 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
