My recent patch [1] to the Linux privcmd module introduced a mechanism to restrict an open file handle to subsequently only accept operations for a specified domain. This patch extends the libxendevicemodel API and make use of the mechanism in the Linux-specific code to restrict operations on the interface handle.
