The problem is that /usr/lib64/python2.6/site-packages/vdsm/constants.py
(from vdsm-python-4.16.0-3.git601f786.el6.x86_64) sets EXT_SASLPASSWD2
to /sbin/saslpasswd2, but the binary is actually in /usr/sbin.

I fixed that and manually set the password (and fixed the ovirt-ha* init
scripts), but still can't deploy a 3.5-beta hosted engine.  When
configuring the management bridge, it leaves the interface down (both
the bridge and the underlying interface); I brought them back up, but
the setup then hits this:

[ INFO  ] Verifying sanlock lockspace initialization
[ ERROR ] Failed to execute stage 'Misc configuration': [Errno 2] No such file or directory

I see this in the setup log:

Not sure what is happening there.
