help
Virtio console for use with lguest and other hypervisors.
+ Also serves as a general-purpose serial device for data
+ transfer between the guest and host. Character devices at
+ /dev/vportNpn will be created when corresponding ports are
+ found, where N is the device number and n is the port number
+ within that device. If specified by the host, a sysfs
+ attribute called 'name' will be populated with a name for
+ the port which can be used by udev scripts to create a
+ symlink to the device.
