A reason why a VCPU exited. One of these returns every time Vcpu::run is called.

Variants

Io

An io instruction needs to be emulated. vcpu handle_io should be called to handle the io operation

Mmio

A mmio instruction needs to be emulated. vcpu handle_mmio should be called to handle the mmio operation
