IRQ coloring is a new concept that dictates that interrupts assigned to workloads (e.g., VMs) are classified according to a specific criticality level. The basic idea consists of selectively deactivating/deferring interrupts of non-critical workloads if the QoS of critical workloads drops below a specific threshold.
