[SOLVED] Regenerate and distribute host keys

[bensode]

I have been playing with adding/removing hosts within a PVE cluster. Somewhere along the lines the host keys were lost as I am unable to perform migrations between hosts with this error:

2019-06-07 09:46:40 # /usr/bin/ssh -e none -o 'BatchMode=yes' -o 'HostKeyAlias=prdpvessd01' root@10.0.3.145 /bin/true
2019-06-07 09:46:40 Host key verification failed.
2019-06-07 09:46:40 ERROR: migration aborted (duration 00:00:00): Can't connect to destination address using public key
TASK ERROR: migration aborted

I can open a shell console to and from each node without a password.

Figured it out ... just had to ssh to/from each node with the host key alias in the task and accept it. IP and FQDN existed but not the host alias.
