[Users] NoRouteToHostException when adding F18 host to engine built with latest source.

[Laszlo Hornyak]

Hi Sharad,

I am not sure this is related, but in F18 if you change the name of the engine host at installation from the default 'localhost.localdomain' then it will not appear in the /etc/hosts file and the system will not be able to resolve the address of the host it is running on and this breaks some functionality in most java programs. Probably this is the reason of the exception you get, not that the engine is not able to connect to vdsm.

If this does not solve the problem, could you increase log level? A stack trace would be great :)

Thank you,
Laszlo
