KVM and CPU
I know that on OpenVZ VPS you can not run CPU intensive tasks 100% of the time, because CPU resources are shared. It's ok and useful in many scenarios.
Is it possible to utilize 100% of the cpu limit on KVM VPS (like on physical dedicated server), or it depends on the settings? And all these details (how CPU cores are shared, and whether I can use 100% of my CPU limit) are not always mentioned on the site of the hosting provider? Am I right?
For example, I want to make tiny MMORPG (multi-player game) that may utilize 80-90-100% of vCPU. Is KVM VPS suitable for this purpose? Or it may cause service degradation, if KVM is misconfigured and does not provide proper strict allocation of CPU resources?
