Would you mind testing by doing: cd /tmp wget https://code.launchpad.net/~brightbox/vmbuilder/exclude-first-cylinder/+merge/42530/+preview-diff/+files/preview.diff cd /usr/lib/python2.6/dist-packages patch -p0 < /tmp/preview.diff then re-building your VM? ** Changed in: vm-builder (Ubuntu) Status: New => Incomplete ** Changed in: vm-builder (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/747068 Title: /tmp = EXT3, the VM images gives EXT4-fs error -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
