[Xen-users] xen-3.3 missing xenbr0 new tmpbridge

Hallo xen-user,

after compile and install src/xen-3.3.0
xenbr0 missing.

Network to DomU works,
but xenbr0 missing.
Is xenbr0 no more needed?

I need xenbr0 for the binding TAP for qemu on dom0.

Whats going wrong?

I accomplished some tests.
Without result.

regards Torsten
