I've no idea - that's very odd

Hmm, virbr0 corresponds to the default network, so not sure why the device
would be present if it were not active. Can you show 'virsh net-list --all'
One possibility I can think of is that something else had created the virbr0
device before libvirt_qemud started & thus prevented it from starting its
own default network. A simple reboot to clear out an pre-existing network
state might just do the trick there.

That is correct XML file to have.

A shared physical device, is any real NIC which is enslaved as part of a bridge.
If you were using Xen, then the Xen startup scripts automatically put 'eth0'
into a bridge 'xenbr0'. With non-Xen we don't try to second guess what the admin
might want for their network setup, so we don't touch the real NICs ourselves.
If you want to have a shared physical device available then you can use the
regular distro provided network scripts, eg creating a suitable config file for
the bridge device at /etc/sysconfig/network-scripts/ifcfg-br0 and then in the
ifcfg-eth0 file setting BRIDGE=br0
