Soren, You are correct, I cannot ping the gateway from the guest - however I can from the host.
The output of 'brctl show' on the host is as follows ## START brctl output ### $brctl show bridge name bridge id STP enabled interfaces br0 8000.001999705a61 no eth0 vnet0 ## END brctl output ## >From looking at this it looks like I should have my guest configured to use the vnet0 interface instead of br0? Why when the testbox.xml VM configuration file is configured to use br0 is vnet0 being created when I start the VM via virsh? brtables has not been modified in any way. Serge, thanks for your input but I can't really do a traceroute easily because I can't connect this guest to the internet to download any packages or dependancies for the tcptraceroute program. It's really strange, the host and the guest communicate fine. Any more ideas? Kind Regards, Jamie.
