We found a problem in
https://github.com/stackforge/fuel-web/blob/201059f83ddce15198607e90994d2b14e807cf04/bin/agent#L442-L455

When method

IPAddr.new("some non api string")

Called it stuck on several seconds, with several interfaces we have several minutes additional timeout.

The problem is VMware specific, on virtual box it works almost instantly.

This problem is not VMware specific, we've reproduced the same problem on KVM.

[Matthew Mosesohn (raytrac3r)]

Reproduced on VBox. Patch works great.
