[PATCH V3 1/3] libxl: virtio: Remove unused frontend nodes

[Viresh Kumar <viresh.kumar@xxxxxxxxxx>]

Only the VirtIO backend will watch xenstore to find out when a new
instance needs to be created for a guest, and read the parameters from
there. VirtIO frontend are only virtio, so they will not do anything
with the xenstore nodes. They can be removed.

While at it, also add a comment to the libxl_virtio.c file.
