How hot-plugging works on the Linux KVM platform
On the KVM platform, to create and hot-plug an interface into a vRouter, you can use the following command on the host KVM system.
virsh attach-device <vm-name> [ --persistent ] <xml-filename>
To detach interfaces from a running vRouter , you can use the following command.
virsh detach-device <vm-name> [ --persistent ] <xml-filename>
Note: On a Linux KVM platform, as many as 32 interfaces can be hot-plugged into a vRouter .
Note: The virsh tool is available through the libvirt toolkit.
