My problem is:
1.) VM1 running on host A must have network access to VM3 when VM3
is running on host B by default _and_
2.) when VM3 is running on host A because host B failed.
In some of my configurations 1.) worked but 2.) not, in some other
configurations 2.) worked but 1.) not.
I must have missed some detail ...
I do not see the problem. With the bridged scenario every VM has
direct access to the physical network and it is not important on
which host it runs. If the VMs are running on the same host, their
ethernet frames will just "turn around" in the bridge interface and
if they are running on different hosts they will go thru the real
ethernet.
State 1)
A: VM1
B: VM3
Eth. frames will go like this: VM1->BrA->PhysCardA->Ethernet-
>PhysCardB->BrB->VM3
State 2)
A: VM1+VM3
B: x
Eth. frames will go like this:
VM1->BrA->VM3
NOW I've got it!
The errors in my configuration were two different network
configurations on host A and on host B - I always thought that the
network on host A and the network on host B must have different IP
addresses. Now there is only on network configuration for host A _and_
host B and everything is fine!
Thank you very much for your help!
