Bug Description
I tried unsuccessfully to add HA mode to nova-cloud-
It looks like the memcached charm is required but it did not help. Note that my understanding is that memcached was a requirement starting with the 19.04 release of OpenStack Charms [1] and ceased being the case when the nova-consoleauth daemon (which talks to memcached) was removed in 19.10 (see bug 1848478).
Anyway, to attempt to add HA to n-c-c to a known-working cloud I did:
juju add-unit -n 2 --to lxd:1,lxd:2 nova-cloud-
juju config nova-cloud-

juju add-relation nova-cloud-
juju deploy --to lxd:1 --bind public-space cs:memcached
juju add-relation memcached:cache nova-cloud-
The result is that each n-c-c unit goes into an error state and each can show a myriad of hook failures (e.g. "memcache-
All applications in the model are using the same default network space 'public-space'.
