That's plain log noise, since you do not have vdsm-json installed. oVirt
currently uses only xmlrpc, so this is not a real issue. I suppose that
the language of this line should be fined to something like "If you
really want jsonrpc, please make sure it is installed".

It seems that vdsm has stopped since the host was rebooted...

the only remaining question is why vdsm did not start up after boot. Could it
be that it is missing `systemctl enable`?

vdsClient -s 0 getVdsCaps

would access localhost vdsm (assuming you are using the default ssl). If it
barfs, we have a problem.
