Marek Marczykowski-Górecki 202e3df6b6 vm/mixin/net: disconnect network interface on backend shutdown/crash ... Since we have more reliable domain-shutdown event delivery (it si guaranteed to be delivered before subsequent domain start, even if libvirt fails to report it), it's better to move detach_network call to domain-shutdown handler. This way, frontend domain will see immediately that the backend is gone. Technically it already know that, but at least Linux do not propagate that anywhere, keeping the interface up, seemingly operational, leading to various timeouts. Additionally, by avoiding attach_network call _just_ after detach_network call, it avoids various race conditions (like calling cleanup scripts after new device got already connected). While libvirt itself still doesn't cleanup devices when the backend domain is gone, this will emulate it within qubesd.
