From e13255b6c5d8b93d1c1d774530e16f4eee1b8cb9 Mon Sep 17 00:00:00 2001 From: Keir Fraser Date: Tue, 25 May 2010 09:08:34 +0100 Subject: xend: Add interface name definition support for xend-relocation-address Add a new feature for xend-relocation-address option to support definition by interface name which can be useful for people having e.g. a cluster environment with multiple network interfaces on all of the machines with only one reserved to be registered to a private cluster network. This way they won't need to specify the relocation address manually on all the machines but just simple providing the interface name to get the IP address from would do the job (all the machines have to have this interface named the same to make it working, of course). Technically it reads the interface name and gets its IP address using ioctl call of SIOCGIFADDR and if the interface doesn't have the address, i.e. if non-existing interface or hostname was provided the original ifname is returned to preserve the old behaviour.
