Implement CPU pinning

[MakiseKurisu]

While this can be done by 3rd party script, running on non SMP system requires this to be set before KVM was even started, otherwise you get error qemu kvm_arm_vcpu_init failed: Invalid argument". This is a known limitation of QEMU.

As for why this PR is related to pimox, this enables me to run VM on Rock Pi 4B which uses RK3399:

However I have not tested the stability on this approach. All I will say is that right now I can click "Start" button from GUI and everything seems to work.

老哥你好，我修改了QemuServer.qm。
当我启动VM的时候报错，提示：
kvm: -c: invalid option
当我使用qm showcmd 的时候，
-mon 'chardev=qmp-event,mode=control' -pidfile /var/run/qemu-server/501.pid \ -daemonize \ taskset -c 5 \ -smbios 'type=1,uuid=aae9b0ba-79f8-4e7e-a598-9a8a911541af' \
我想应该是KVM 不识别-c这个参数。
请问我是否修改错误了。

我好像明白了。应该是taskset -c 在/usr/bin/kvm之前。

都是不太明白
kvm: kvm_init_vcpu: kvm_arch_init_vcpu failed (0): Invalid argument
怎解決

Hi,

I don't know if solves for you, but at least i was having same issue after applying patch. In my case i needed to reboot once change made

I did this on a orangepi4-lts (rk3399) running armbian:

Linux proxmox 5.15.69-rockchip64 #22.08.2 SMP PREEMPT Wed Sep 21 19:28:26 UTC 2022 aarch64 GNU/Linux

This was the vm conf i tested on. It is based from Pimox HassOS VM image
