In the project, this element will be used to limite the virtual machine (more details here).
- The
emulatorpin
element specifies which of host physical CPUs the emulator, a subset of a domain not including vCPU or iothreads will be pinned to. - The
vcpupin
element specifies which of host's physical CPUs the domain vCPU will be pinned to (more details here). It's used to reserved one or more CPUs for a critical virtual machine. So, it's important not use this CPU on another VM. - The
vcpusched
element specifies the scheduler type for a particular vCPU.
