That blames open-iscsi, but the problem is now tgt.  Cinder seems to have 
switched from open-iscsi to tgt.

The install of tgt inside the LXC fails.  Here is what that looks like:

# apt-get install tgt
...
Setting up tgt (1:1.0.43-0ubuntu4) ...
start: Job failed to start
invoke-rc.d: initscript tgt, action "start" failed.
dpkg: error processing package tgt (--configure):
 subprocess installed post-installation script returned error exit status 
1
Processing triggers for libc-bin (2.19-0ubuntu6) ...
Processing triggers for ureadahead (0.100.0-16) ...
Errors were encountered while processing:
 tgt
E: Sub-process /usr/bin/dpkg returned an error code (1)

What's going on is that the install script for the tgt package launches 
the daemon, tgtd.  That launch fails.  Here is a typescript showing more 
details of how it fails:

# tgtd -d 1 -f
librdmacm: couldn't read ABI version.
librdmacm: assuming: 4
CMA: unable to get RDMA device list
tgtd: iser_ib_init(3351) Failed to initialize RDMA; load kernel modules?
can't adjust oom-killer's pardon /proc/self/oom_score_adj, Permission 
denied

Thanks,
Mike
