[libvirt] does libvirt support qemu-kvm vmchannel option?

[cyliu7]

Hi all,

I noticed that qemu-kvm support an option vmchannel (-net channel ...) 
to create a new device to communicate between host and guest.

does libvirt support this option when creating a KVM based VM. if so, 
how to config the VM? is there any sample to show this feature?

any suggestions are greatly appreciated.

Regards,
