Hi, I'm noticing a ssh key being inserted automatically inside the host node and wanting to know how/why is it? I have created and added my own keys BUT I'm also seeing an additional key being inserted. I delete it and it comes back again. Any advise/suggestions how to fix or resolve this. Could proxmox be doing this?

Hi,
inside a cluster the ssh known_host file and the root authorized_keys always includes all other nodes public keys and info, to allow things like migration.
Further, the nodes own keys is always added, even on a single node "non cluster", so that on cluster join it can be already used immediately.
This is checked on each start of the cluster filesystem, so normally on every boot or upgrade of that filesystem package.
You can see that some ssh related files are linked to the clustered configuration filesystem:
