Using __del__ is somewhat unsound resource cleanup in our clase the
logger already closed its logfile and therefor fails with exception
before the rest of the resources can be cleaned up.
We remove the global rootlog in favor of instantiating the logger as
required in the __init__.py and pass it down as a parameter (of our
AbstractLogger type).
Within a dual VM test-setup a strange behaviour was observed.
The two VMs are connected via one vde_switch instance
(instancevirtualisation.vlans = [ 1 ]; IMO a bad attribute name for
switch instances, has nothing to do with VLANs in sense of 802.1Q).
A ping on the base interface (eth1) works, but not on VLAN
subinterfaces (vlan1@eth1). A tcpdump of eth1 includes the ARP requests
tagged with the subinterfaces VLAN ID, but responses seems not to pass
the vde_switch. This works fine if performed on the base interface.
Putting the vde_switch in hub mode results in flooding
traffic to all vde_switch ports. This results in a expected behaviour
and a ping on a VLAN subinterface works as expected.
