Re: [PATCH libvirt v1 1/3] virsh: add `console --resume` support

This patch adds the command line flag `--resume` to the `virsh console` command. This resumes a paused guest after connecting to the console. This might be handy since it's a "common" pattern to start a guest paused, connect to the console, and then resume it so as not to miss any console messages.
