vmbuilder should generate a proper /etc/mtab file in the disk image / chroot before running grub. For some reason grub requires that /etc/mtab contains the root partition in the mtab list.
embedded mode for grub fails since vmbuilder makes partitions starting from sector 1. virt-manager starts from sector 63. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to vm-builder in Ubuntu. https://bugs.launchpad.net/bugs/610652 Title: vmbuilder randomly fails to install grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/vm-builder/+bug/610652/+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
