Virtualization performance monitoring method, apparatus, device and medium

An electronic device, comprising:

• a storage apparatus, storing a computer program thereon;
• a processing apparatus, configured to execute the computer program in the storage apparatus to:
• acquire a first time stamp of a virtual central processing unit VCPU process entering a virtual machine mode and a second time stamp of the VCPU process exiting from the virtual machine mode to a host mode;
• acquire a third time stamp of the VCPU process executing a target instruction in the host mode and a fourth time stamp of the VCPU process receiving a wake-up instruction in the host mode, wherein the target instruction is an instruction for causing a CPU to enter a suspended state;
• determine a CPU usage occupied by the VCPU process running in the host mode based on the first time stamp, the second time stamp, the third time stamp and the fourth time stamp;
• and
• determine a virtualization overhead based on the CPU usage.

A non-transitory computer-readable storage medium, wherein the storage medium stores a computer program, and the computer program is used to:

• acquire a first time stamp of a virtual central processing unit VCPU process entering a virtual machine mode and a second time stamp of the VCPU process exiting from the virtual machine mode to a host mode;
• acquire a third time stamp of the VCPU process executing a target instruction in the host mode and a fourth time stamp of the VCPU process receiving a wake-up instruction in the host mode, wherein the target instruction is an instruction for causing a CPU to enter a suspended state;
• determine a CPU usage occupied by the VCPU process running in the host mode based on the first time stamp, the second time stamp, the third time stamp and the fourth time stamp;
• and
• determine a virtualization overhead based on the CPU usage.
