I have successfully used Virtual Machine Manager to create a KVM/QEMU virutal machine running Windows XP.
This has created a virtual bridge (virbr0) with the IPv4 configuration:
DHCP start: 192.168.122.2
DHCP end: 192.168.122.254
In Windows ipconfig gives me
Subnet mask: 255.255.255.0
Standard gateway: 192.168.122.1
So far, so good, but the bridge does not seem to be forwarding properly. If I ping the server in the physical network, I get nothing. I can't find the Internet, I can't find the local network.
What do I need to do to get this to work?
