I have been able to test a potential fix for this problem. The unmap() function is responsible for tearing apart the device maps created by the kpartx commands. Those are created by the map_partitions() function.
While tearing down the device maps created by the parted command, which is invoked in the partition() function might be better done by a callback in the partition() function, the patch is simpler by adding to the existing unmap() which is a callback from map_partition, which is invoked sequentially after partition() in hypervisor.py. Please let me know if the patch in the proposed branch is unacceptable. -- 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/531599 Title: device mappings for partitions not removed after build using --raw, leading to filesystem corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/vm-builder/+bug/531599/+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
