vcpupin که تعداد هسته ها هست.
emulatorpin cpuset تعداد cpu فیزیکی هست.
shares همون مقدار unit هست.
quota همون مقدار %cpu هست اینجا اگه مقدار 100000 باشه یعنی 100% اگه به یه vps مقدار 20% بخای بدی باید 20000 باشه.
period مقدار چرخه هست و مقدار quota به این وابسته هست قبلا گفتم مقدار 100000 واسه qouta میشه 100% از مقدار استفاده cpu زمانی این مقدار درسته که واسه period هم مقدار 100000 باشه یعنی مقدار period میشه 100% quota.ممکنه واسه این توی virtualzior مقدار period رو 100000 گذاشتند که محاسبه درصد راحت تر باشه
میبینید که همه مقادیر توی پنل virtualizor هست و چیزی از قلم نیفتاده و نمیشه مقدار فرکانس رو محدود کرد با این مقادیر
توی سرور اصلی اگه دستور virsh help رو بزنید دستورات جالبی میاد که در واقع virtualzior/solusvm همین دستورات رو بصورت گرافیکی کردند فقط.
