Original GitHub issue: https://github.com/retspen/webvirtmgr/issues/46

For some reason, when I add a network pool, no matter what I choose from the "Type Forwarding" menu, after creation of the pool it is listed as "ISOLATE" .

Maybe this a problem with my configuration? If so, it'd be good to have some kind of alert from webvirtmgr warning me about this.

Hey boozedog,
There are actually many more network options and forwarding methods than seen in the WebUI. I was actually looking for a direct bridge network configuration without any NAT'ing / forwarding. I am in the process of implementing that option. Is there a particular option you were looking for?

I also have a problem similar to this. I prefer to create all network bridges myself, and WebVirtMgr is refusing to use my bridge.

br0       Link encap:Ethernet  HWaddr 00:30:48:C3:A6:B4  
          inet addr:192.168.2.5  Bcast:192.168.2.255  Mask:255.255.255.0

When I attempt to add this network to WebVirtMgr, I get the following error:
Input subnet pool error

I am adding:
Name: br0
Network: 192.168.2.0/24
No DHCP

Use IPcal to calculate your network. Example: br0 - 192.168.2.5/32 gw 192.168.2.1; virbr0 - 192.168.2.8/29 gw 192.168.2.9(Routing). WebVirtMgr can create sunbnet if you input correct netmask to route network on bridge device then need add route this network on your GW on bridge interface. This error broadcasts Libvirt not WebVirtMgr.
