I've just found this:
domiftune domain interface-device [[--config] [--live] | [--current]] [--inbound
average,peak,burst] [--outbound average,peak,burst]
Set or query the domain's network interface's bandwidth parameters.
interface-device can be the interface's target name (<target
dev='name'/>), or the MAC address.
If no --inbound or --outbound is specified, this command will query and show the bandwidth
settings. Otherwise, it will set the inbound or outbound bandwidth. average,peak,burst is
the same as in command attach-interface.
If --live is specified, affect a running guest. If --config is specified, affect the next
boot of a persistent guest. If --current is specified, affect the current guest state.
Both --live and --current flags may be given, but --current is exclusive. If no flag is
specified, behavior is different depending on hypervisor.
I'm gonna try it.
I thought the edit command was to perform on-the-fly editing of VMs
I should have read the manual :)

I haven't gone through the code to tell for sure, but for now you can
only set the network part of QoS (via virsh net-update) while the
domain's interface is not supported yet. However, patches are welcome :)
