Error Errno::EHOSTUNREACH (No route to host - connect(2)): when trying to download templates

[GoogleCodeExporter]

Steps to reproduce:
1. Install ovz-web-panel on a management server (non-openvz)
2. Add a openvz server to the web panel
3. Navigate to the server in the web panel
4. Click "OS Templates"
5. Click "Install New OS Template"
6. Select an offical template
7. Click Install

Actual result:
Error Message "Failed to start installation of OS templates."
error log attached 

Expected result:
Installation of template

Additional information:
Am able to run the wget command shown in the log manually on both servers with 
success so this isn't a generic routing / network issue.

After further investigation it appears that was caused by the management server 
not being able to connect to the hardware daemon on the hardware node.

To fix (for future googlers) navigate to /opt/ovz-web-panel/utils/hw-daemon on 
the hardware node and start the hardware daemon with:
ruby hw-daemon.rb start

You can check it's running with netstat -tnlp | grep ruby

You should see an entry showing a ruby process listening on port 7767.You'll 
also want to make an appropriate firewall hole between your management server 
and the hardware node.

My take on this issue is that it should be turned into a bug to give a more 
informative error message when there is a failure to communicate with the 
hardware daemon on a node.
