Final answer:
The interval when a virtual machine is ready to execute instructions is called CPU Ready. CPU Ready time is an important metric in virtualization environments as it can impact the performance of virtual machines.
Step-by-step explanation:
The interval when a virtual machine is ready to execute instructions is called CPU Ready. CPU Ready time refers to the amount of time that a virtual machine must wait for a processor to become available before it can execute its instructions.
For example, if a virtual machine has a high CPU Ready time, it means that the CPU is busy handling other tasks and the virtual machine has to wait for its turn to run.
CPU Ready time is an important metric in virtualization environments as it can impact the performance of virtual machines.
