To update the thread here after some offline discussion with Piotr, the
problem was that vdsmd had stopped running and wasn't able to start. It
wasn't reported in the logs that I could see, but I noticed it after trying
to restart it at Piotr's suggestion, after running a 'systemctl'. A
'journalctl -xe' reported:
[root@kvm-ldn-02 vdsm]# journalctl -xe
-- Unit vdsmd.service has failed.
--
-- The result is failed.

So I ran a 'vdsm-tool configure --module sebool', and then I was able to
start vdsmd and mom-vdsm. This fixed the connectivity issue and the node is
now back online.
Many thanks to Piotr for all his help.
Cheers,

Hi Piotr,
Attached are the vdsm log, the engine log and the supervdsm log. I've
attached them as a .tgz.
I noticed it is complaining about configuring an interface in one of the
node logs. It shows as up in the engine web GUI though (and on the command
line).
Thanks for the help.
