Tue Jul 24 09:18:28 UTC 2012
Commands to manage host interface are moved from virsh.c to
virsh-interface.c, with a few helpers for interface command use.
* virsh.c: Remove interface commands and a few helpers.
(vshCommandOptInterface, vshCommandOptInterfaceBy)
* virsh-interface.c: New file, filled with interface commands its helpers.
