[The interfaces are called vnet0, etc]

You're getting confused about what interface is named on the host side
(vnet0 etc) and what the guest sees.  The guest sees eth0 for a Linux
guest, it would be something completely different for a Windows guest.

To list the host devices do:

/sbin/ifconfig vnet0

_on the host_.

As explained here:

http://libvirt.org/formatdomain.html#elementsNICSTargetOverride

the <target dev='...'/> element is optional, and only needed if you
want to specify a particular host network device.  In almost all cases
you would leave it out and libvirt/the hypervisor will pick one for
you.  And if you do 'virsh dumpxml' then libvirt will show you which
temporary host device was assigned to the interface.
