...ts. This thread will finish when the socket is closed by userspace (eg. when the guest is restarted) or by the introspection tool. The uuid member of struct kvm_introspection is used to show the guest id with the error messages. On certain actions from userspace (pause, suspend, migrate, etc.) the KVM_INTROSPECTION_UNHOOK ioctl is used to notify the introspection tool to remove its hooks (eg. breakpoints).

The KVM introspection subsystem provides a facility for applications running on the host or in a separate VM, to control the execution of other VMs (pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.), alter the page access bits in the shadow page tables (only for the hardware backed ones, eg. Intel's EPT) and receive notifications when events of interest have taken place
