Title:
Cannot attach volumes to LXC instances
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
Volumes cannot be attach to any LXC instances
since it's root device cannot be parsed properly.
This later causes a failure in device name generation in
get_next_device_name(),
when attempting to generate a name for the attached volume.
The generated device name, will not be recognized by
get_dev_prefix_for_disk_bus()
when trying to select a disk bus, nor libvirt will be able to attach the
volume
with an unrecognized device name.
When creating a LXC instance, the /dev/nbd1 or /dev/loop0 devices will be
saved as
instance root device in _create_domain()
Later, when attaching the volume, block_device.match_device will be called
from compute_utils.get_next_device_name(),
The formed device will be named as /dev/na (for /dev/nbdX)
Which will not be recognized in blockinfo.get_dev_prefix_for_disk_bus()
Even if it will be recognized, libvirt wont be able to attach a volume named
/dev/na
