Re: lvs-dr with freebsd jailhost as realservers: resolved.

[Mike Bloom <nanogbloom@xxxxxxxxxxxxx>]

Hi,

The problem was that lvs-dr requires the vip to be bound to a lo0 on 
each of the jails, rather than just the jailhosts lo0 interface.
By applying a patch to the jail subsystem that allows multiple ip's 
(http://www.digitaldaemon.com/FreeBSD/FreeBSD/index.html)  I was able to 
run a jail with lo0 assigned the ip of the vip.
I hope this helps some other folks using freebsd jails, this one has 
stumped me for a few days.
