Ok, thank you!

You're right: changed the path and now it's ok.

Done it

Started the Hosted Engine Deployment, but I have a different problem now.

As the installer asked, I specified some parameters, in particular a 
pingable gateway address. Specified the host1 gateway.
Proceeding with the installer, it requires The Engine VM IP address 
(DHCP or Static). I selected static and specified an IP Address, but the 
IP *IS NOT* in the same subnet as the host1. The VMs IP addresses are 
all on a different subnet.
The installer shows a red message:

The Engine VM (aa.bb.cc.dd/SM) and the default gateway (ww.xx.yy.zz) 
will not be in the same IP subnet. Static routing configuration are not 
supported on automatic VM configuration.

I'm starting to think that BOTH the hosts IPs and the VM IPs MUST BE ON 
THE SAME SUBNET.

Is this a requirement or there's a way to deal with this configuration?
It's related only to "automatic VM configuration" or to oVirt in 
general? Once installed oVirt Engine can I have VMs on different subnet?
