How to assign kernels to a process?

Question

linux

Good evening, let's get straight to the point. On vds under Linux + debian container, 2 game servers are installed for 2 users, there was a difficulty in assigning cores to the processes of these servers, there are 4 cores and you need to install 2 cores for each process.
I tried this:
taskset -c 0.1 ./gameserver start
taskset -c 2.3 ./gameserver start
At first everything worked, then after rebooting the machine everything went wrong, confusion began, the process was set to 1.2 cores and did not use others, I didn’t see if they weren’t there, but they are, I checked htop.
Maybe someone knows how to solve the problem, maybe there is a better way?

Answer 1

Obviously, the command tasksetonly affects the gameserver launched from it. Those. this must be done every time the computer is started.

Answer 2

You lift two virtual machines and limit them on use of the processor. That's it, the hypervisor itself will figure out which cores to give out to whom.
