Hi all, I am moving from using LXC to KVM for haproxy on my Debian 7 system. When I start haproxy, I get this error: _________________________________________ Apr 7 10:38:22 localhost haproxy[3418]: Proxy haproxy started.

>From outside the haproxy, I get the error: # wget 192.168.122.112:80 --2015-04-07 10:48:47-- http://192.168.122.112/ Connecting to 192.168.122.112:80... connected.
