Not that I know of, except that the libvirt daemon uses a few additional CPU cycles. Technically yes, in the spirit of the question no. Have a look at your process tree; you'll see command lines in the same way as you'd expect them to be when you start machines manually. > if it does where the overhead goes? quest or host, or maybe both? No additional CPU cycles for the guest, a few additional CPU cycles for the host to get status information and expose it via the daemon. > if overall performance is slower then how small it is comparing to all > the advantages it offers? It is completely negligible. Felicitus _______________________________________________ libvirt-users mailing list [email protected] https://www.redhat.com/mailman/listinfo/libvirt-users
