How to limit clock speed for CPU

[MasterGberry]

Hi. I am creating VM's for proxmox, and I see there is a drop down for different types of CPU's, by default it just uses a core of the regular CPU, but what if I want to limit it?

I have a 1230v2 i7 in my server, and by default the clock speed is 3.2 ghz I believe. I want to limit this down to half of a core for one of my clients, to give him around 1.5ghz or 1.6ghz of processing power. Is there an option to do something like this in proxmox? Do I need to use a different CPU architecture type?

Thanks.

It seems you can limit the CPU, but you can only set how many CPU from the WebGUI. The rest needs to be set in the CLI

Hi. Ok so I need to use the CLI. I am a bit new to cloud computing, and I have the following config file at the moment:

root@proxmox1:~# cat /etc/pve/qemu-server/103.conf
bootdisk: ide0
cores: 1
ide0: XXXXXXXXXXXXXXXXXXXXX,size=20G
ide2: local:iso/CentOS-6.3-x86_64-bin-DVD1.iso,media=cdrom,size=4188854K
memory: 1024
name: tariq
net0: e1000=XX:XX:XX:XX:XX:XX,bridge=vmbr0,rate=25
ostype: other
sockets: 1

So the cores is set to 1 in this config file which i found in /etc/pve/qemu-server/103.conf

What do I need to set to half the amount of power that this core receives? CPUUNITS? How does this compare to the other VM's that don't have this set.

This may help, however, I'm not 100% clear how to limit it by a percentage.
Say 100% of 1 core, or 50% of 1 core. On a quad core rig with only 4 cores @ 50% for 1 core is like 1/8 of the processor. Not sure how that translates to the ghz
