machine-nort: a subgroup ofmachineslice to run all virtual machines with default scheduler.machine-rt: a subgroup ofmachineslice to run all virtual machines with real-time scheduler.ovs: a group to run OpenVSwitch.
All specified CPUs in cpumachines should be also in cpumachinesrt and cpumachinesnort but these variables are complementary in the set of CPUs for machine slice.
Interrupt Requests
irqbalance is a daemon for SMP (Symmetric shared-memory multiprocessing) systems to help balance the CPU load generated by interrupts across all of a systems CPUs. irqbalance identifies the highest volume interrupt sources, and isolates each of them to a single unique CPU, so that load is spread as much as possible over an entire processor set, while minimizing cache miss rates for irq handlers.
