Reload virtual machine settings without restarting (QEMU)

I added a new disk and a network interface, can not restart the machine as it is in use 24 hours.

I am using the machine with the "Proxmox 1.6" to manage virtual machines, and it uses the "qemu / kvm" to make full virtualization.

Does anyone know if it is possible to load the virtual machine settings without having to restart it.

 

Have you tried to mount the new disk and restart the network?

 

Yes, but he does not recognize the new features.
I believe qemu updates the settings (resources) of the machine only when it is restarted.
