The vdsmd startup failing problem is now resolved :) The root cause was that the
/etc/sudoers file (that we maintain a customized version of which thru Ansible) was
missing the "#includedir /etc/sudoers.d" stanza, which caused a sudo problem
with the vdsmd startup, since the sudoers include file "50-vdsm" wasn't
being parsed.
In going back and reviewing the thread, this was the first post that pointed out the real
problem...

Any clues out of the strace of vdsm?
read(9, "sudo: a password is required\n", 4096) = 29
Could it be that sudo is not configured to operate passwordless?
The strat-up can then fail, because sudo requires a ty, but this isn't available
during service start.

Can you please use strace on it?

However, not knowing about the missing sudoers include file, we continued to chase a vdsm
config problem (uninstall / reinstall vdsm RPM pkgs, & use "vdsm-tool configure
--force")
Shame on me, it looks like I didn't think to check /var/log/messages for
"vdsm"-string entries until today, where we found the "vdsm user could not
manage to run sudo operation: (stderr: ['sudo: sorry, you must have a tty to run
sudo']). Verify sudoer rules configuration” message that ultimately led to the
solution :(
However, not sure if it's possible to do so, but could /usr/share/vdsm/vdsm be made to
emit a error to STDERR if it cannot run correctly? That's the only thing I could think
of that may have helped me to resolve this earlier with what I did do...
Thanks for everyone's kind assistance, this really is a great community! :)
