Looking for some help/suggestions to correct an issue I'm having.  I have a 3 
host HA setup running a hosted-engine and gluster storage.  The hosts are 
identical hardware configurations and have been running for several years very 
solidly.  I was performing an upgrade to 4.1.  1st host when fine.  The second 
upgrade didn't go well...On server reboot, it went into kernel panic and I had 
to load previous kernel to diagnose.  



I couldn't get it out of panic and I had to revert the system to the previous 
kernel which was a big PITA. I updated it to current and verified installation 
of ovirt/vdsm.  Everything seemed to be ok, but vdsm won't start. Gluster is 
working fine.  It appears I have a authentication issue with libvirt.  I'm 
getting the message "libvirt: XML-RPC error : authentication failed: 
authentication failed" which seems to be the core issue.



I've looked at all the past issues/resolutions to this issue and tried them, 
but I can't get it to work.  For example, I do a vdsm-tool configure --force 
and I get this...





Checking configuration status...



abrt is already configured for vdsm

lvm is configured for vdsm

libvirt is already configured for vdsm

SUCCESS: ssl configured to true. No conflicts

Current revision of multipath.conf detected, preserving



Running configure...

Reconfiguration of abrt is done.

Traceback (most recent call last):

    return tool_command[cmd]["command"](*args)

line 98, in configure_passwd

    raise RuntimeError("Set password failed: %s" % (err,))

RuntimeError: Set password failed: ['saslpasswd2: invalid parameter supplied']



...and help would be greatly appreciated.  I'm not a linux/ovirt expert by any 
means, but I desperately need to get this setup back to being stable.  This 
happened many months ago and I gave up fixing, but I really need to get this 
back online again.



Thank you
