Virtual Server Resource Allocation

[gutter007]

I have a proxmox server, and I want to know if there is a general rule of thumb to allocate resources on the server.

Here are the stats for the physical server:
Proxmox 2.0
CPU: 6 Cores
12 threads

Storage: 500 GB
Memory: 32 GB

I want fully utilize the server without over allocating the server. Is there a rule of thumb about how to allocate the resources?

If I'm provisioning kvm's, are there certain items I should allocate only the amount on the server, or can I overbook certain items safely?

What is the difference if I'm using vz containers?

thanks.

I would not overbook memory, but it is safe to use more cpus than you have (that just degrades performance on the VMs).

But this totally depends on your use case. Many people overbook RAM, and let KSM merge memory. But that is
not 100% safe IMHO.
