Zentyal does not provide HA. They started down that path a few versions ago before backing away from it. For me Zentyal still manages email and authentication services (AD). I am actively shopping for replacements as Zentyal no longer really fits my needs. I am taking a very hard look at...
Zentyal has a very convoluted way of defining reservations. First you define an object under network and then under dhcp advanced options you can add static reservations for that object. Confusing to say the least.
I have long since moved my dhcp functions over the pfsense. It was a...
Did you actually set the netmask for the proxmox machines to /32 ie 255.255.255.255?
That creates a network of 1. All outbound traffic from 192.168.1.116 would then be sent to the gateway address which you haven't included here.
Going off that assumption I suggest instead setting all...
Eventually you will probably run across the use case of needing the same feature for VM's. This is predicated on the kvm agent being installed.
qm guest exec <vmid> -- "wget" "http://gitlab.myrepo.com/root/my-test-item/-/raw/master/authorized_keys" "-O" "/root/.ssh/authorized_keys"
You can take a look at this thread for another option random-crashing-freezing

You can push the desired ssh keys into the running container from the proxmox host with something like
pct push <vmid> authorized_keys /root/.ssh/authorized_keys
That would let you in turn ssh in and start customizing via ansible.
Also, I might suggest setting up an syslog-ng server on another computer and send your logs to it via rsyslog. This might allow the server to gasp out a final message in a situation where the disk subsystem has already expired.
