Hi all,

some more hints that would have saved me a lot of time:

If your eth0 is a wireless device, it might be a good idea to switch to another
device to try this. Many wireless devices have problems with bridged networking.
I switched to my wired network after a lot of testing and had success.

If you do not provide a mac addr on the commandline of qemu / kvm a static
macaddr will be used, giving you problems starting with vm no2.
In the guest an interface eth0 is instantiated with this fixed macaddr
which can be configured as usual
If you provide a macaddr the interface is instantiated as eth1 instead of eth0.
I do not understand why, maybe someone can acknoledge this fact.
Anyway thinks worked when I switched to eth1 in my hosts.

An article that helped me a lot was:
