This gives you ability to run the "set_link" monitor command above, and then run "cont" to actually start the VM. Less convenient that a CLI flag, but functionally it is eqivalent. -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1659267 Title: It's not possible to start a VM with a network cable unplugged Status in QEMU: New Bug description: There should be a command line (sub)option to unplug a network cable. While from the monitor interface I can issue: set_link virtio-net-pci.0 off There's no way to fire a VM from command line with that cable already unp= lugged. As an example, virtualbox can do it.
