Hi all,
any comment / suggestion on the steps described above? Does a simpler
approach exists?
Hi list,
any insight on bridge vs macvlan setup previously described? Am I
over-thinking it?
Thanks.

I generally use plain bridge for my KVM setup. Specifically, when
using VLANs I setup the following:
eth -> eth.xx -> bridge -> vnet
This time, however, I need *both* a trunk-enabled VM (a virtual
firewall) and other segregated virtual machines. A "

I understand. But in my opinion, inter-guest communication should be
preserved because:
a) this is how the

Can you share the configuration for your guest NIC so we
can see how it is setup.
Here we go...

# ifconfig
Both the physical and macvtap interfaces are disconnected (note how
RUNNING is missing):

Dear list,
I just discovered the hard way that if the lower lever physical
interface of a macvlan bridge is disconnected (ie: by unplugging the eth
cable, resulting in no carrier), inter-guest network traffic from all
virtual machines bound to the disconnected interface is dropped.
