Once connected via SSH it's just like sitting at the machine terminal. All the normal KVM commandline tools are available and no third party libraries required...
As for the daemon question, I have no experience with ESXi (besides my brief testing of it prior to finding ProxmoxVE) and wasn't aware that it doesn't have a daemon. I would've thought that would be a bad thing!? A daemon is essentially a service that runs all the time and will (AFAIK) try to restart if something goes wrong and it crashes. I would think that that is what you want the core of a hypervisor to do. So I have no idea how ESXi would be able to provide a stable hypervisor layer without some sort of daemon. But then again I'm guessing that they employ plenty of people smarter than me! :)
