I actually don't see any errors in the log file contents below (you can 
ignore the silly AssertionError thing about threading.pyc).

Perhaps you could try executing the underlying volume creation commands 
as root and see if you get any output or if things just hang? From what 
I can tell, those commands would be:

sudo lvcreate -L 1G -n volume-00000001 nova-volumes
sudo tgtadm --op new --lld=iscsi --mode=target --tid=1 
--targetname=iqn.2010-10.org.openstack:volume-00000001

Also remember that your nova-volumes volume group must have enough size 
in it to create this volume!

Best,
