When I bring up virt-manager, got settings for my VM, and for "Network
Source" I select
"Specify Shared Device Name" and I have tried the virbr0 and clicked apply
and boot the machine. I get networking but not bridged networking - not a
192.168.1.X address.

Is there something I missed ?
Thanks,

Jerry
