Yep, it sounds like one of these would be the problem:

 a) Libvirt on the Linux server is not listening for tcp connections, or

 b) There is a firewall stopping the connection from getting through

    This could be on your windows box, stopping the outgoing connection,
    or could be on the linux server, stopping the incoming connection.

    Depending on your network, there could be some kind of firewall in
    between too.

Probably the first thing to check for, is a).

>From the Linux server, try opening a telnet connection to itself, going
to the tcp port Libvirt should be listening on (16509).

For example:

  $ telnet 192.168.1.8 16509
  Trying 192.168.1.8...
  Connected to 192.168.1.8.
  Escape character is '^]'.

If it makes a connection, then Libvirt is set up ok, and your problem
is more likely a firewall.

If it doesn't work, then the Libvirt configuration needs adjusting.
You'd need to tell Libvirt to listen for tcp connections.  That's easy,
but the files to adjust depend on the version of Linux you're using.

Which version of Linux are you using? :)
