We use virsh detach-device to hot-unplug a vhost-user net card, and libvirtd will issue qmp_netdev_del, qmp_chardev_remove and qmp_netdev_del. However, in qmp_netdev_del, qemu will remove the chardev when cleanup the netdev. So libvirtd has no need to issue qmp_chardev_remove to qemu any more.

Is this true for all versions of qemu? Or do these lines hurt some use cases? Michal
