Separate Hardware and Virtualization Controler

[Misinthe]

Hey everyone, my questions is, can you have, let's say Proxmox, install on one server and from that server install and manage virtual machines on another server that provides hardware? Or do I need to install Proxmox on each server with their individual VMs?

 

Thank you,

Proxmox VE needs to be installed on each server that is a VM host (called a node). When you create your "clusters" you will use 1 node as your "Primary Node" which is where you create your clusters, and that will generally be your management.

You would need to install Proxmox on each server that you want to manage, but you should then be able to manage them all centrally by setting up some sort of cluster. This page may be of use to you.

Thank you both, do you have any idea of what kind of performance I would lose by doing this? My thing is, if I have 2 servers with a xeon 4C8T, after installing Proxmox, how many available Cores and Threads would I have available to create VMs?

basically nothing, probably like 2-5%.

 

Proxmox its self uses basically no resources.

 

ALso you don't have to give vms deticated cores, most vm uses are overprovisioned, so there are 4 virtual cores for every physical cores for example.

So they only use the resources when they needed? It's basically just a max pool?

yea the vms only use the cpu, ram(optional), and disk io as needed. For a home server one of those systems should be a good start. Id just setup vms with like 2 or 4 cores by default, and 2048mb of ram, and keep adding them until you have performance issues. Normally your ram limited with vms before cpu.

 

The os its self needs basically nothing

Awesome, thank you for the information!
