[Engine-devel] Failed to configure management network on the host

Hi Sahina,

I was able to reproduce it on my setup, it seems that when a host was
already installed and the user re-installed it, it failed to check the
host availability.

I fixed the host polling by the engine by commit
5c03a936df3a09473f1a05b973680c02280d7a5c.

You can either build from master or wait for the nightly build.
Please let me know if there are more issues.

Thanks,
Moti
