[Xen-devel] [PATCH] >1 IP address on eth0 causes hotplug script failure

[James Dykman <dykman@xxxxxxxxxx>]

Adding a second IP address onto eth0 causes the vif-* hotplug scripts to 
fail: ip_of() is returning a LIST of IP addresses, one per line.
The vif-scripts attempt to use the list where single addresses ought to 
be, with predictable results. This patch changes ip_of() to return
the first address in the list, which seems to be the first one configured.

This came up while testing the patch for the checksum errors on IPSEC 
tunnels. I added an IP address for the tunnel on eth0 and
domUs wouldn't start anymore. 

Since this changes vif-common.sh, I ran xm-test using -bridge, -route, and 
-nat scripts, each with 1 and 4 IP addresses on eth0.
