[Linaro-validation] lava-cloud04 and lava-cloud05 issues

Hey Dave,

I was messing around with our VM's today and noticed a couple of issues:

1) lava-server05 bridge not working When I launched an instance that started on lava-cloud05 I couldn't get to it via its public IP address. lava-cloud05 could ping the public IP, but not lava-cloud01 or anything else in our lab.

2) lava-server04 has errors when trying to launch an instance I have no idea what was going on here.

Luckily I was able to do what I wanted which was to get two instances going. fastmodels02 found its way to lava-cloud02 which was idle.
