[libvirt-users] question about vm management in libvirt

Dear, I am a beginner of using libvirt to manage the vm, and I checked the libvirt manual. And I found the libvirt can creat, destroy, start and stop the vm, and it can manage The resource of the vm, such as storage, cpus, memory, networking and so on. And I have one doubt, Can It know the vm internal running state? Such as vm reboot, Exception, hang up, or signals received by the vm processes. I am using qemu driver. Thanks and Regards, Kevin
