I added this corresponding line: def unmount_dev(self): self.context.cancel_cleanup(self.unmount_dev) run_cmd('chroot', '%s' % self.context.chroot_dir, '/etc/init.d/cron','stop') // <-- HERE run_cmd('umount', '%s/dev' % self.context.chroot_dir)
That seems to be a temporary workaround for the problem I was seeing (same as @rchilliard -- lsof showed a cron open file to /dev/null). I also had this working up until several days ago without anything else changing and then it suddenly broke. -- 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/879710 Title: ubuntu-vm-builder crashes when trying to umount tmp directory.
