[Xen-devel] [PATCH] Each TAP/TUN device name for a HVM guest includes its domain ID.

[MIYAJIMA Mitsuharu <miyajima.mitsuharu@xxxxxxxxx>]

The TAP/TUN devices are used for connection to a HVM domain, but there
is no relationship between each name of the devices and its domain ID.

This patch assigns a HVM domain ID to each name of the TAP/TUN devices.
