[libvirt] set link state for ethernet network devices

Hi! Sometimes ago i'm write patch for setting link state of network interface for ethernet type (tap). Now i'm try libvirt 3.3.0 and see, that tap interfaces is up but in xml i'm try to specify <link state='down'> also i'm try <source><link state='down'></source> Nothing changed. Laine says, that link state is only for internal representation, and to modify link state on host side i need to specify <source><link state='down'></source>. For history please check email thread "qemu: remove unnecessary setting of tap device online state" So does this bug or it my mistake? Thanks! -- Vasiliy Tolstov, e-mail: v.tolstov(a)selfip.ru
