Virtual bridging between 4 VM.

$

Hello Folks,

 

I need to setup infrastacture where I need to bridge 3 different VM's via 2 different distinct bridge group

and it has to be completly virtual so no physical mapping.

 

VM 1 -- BR1 -- VM 2 --- BR 2 --- VM 3

 

Initially, I thought to use tun/tap inteface and use mapping like


tap0 mapped to VM1 via vmnet bridge

tap0 mapped to VM2 eth1

tap1 mapped  to VM2 eth2

tap1 mapped  to VM3 eth 1

 

and use something like this

vmnet-bridge vmnet10 tap0 &

vmnet-bridge vmnet11 tap1 &

 

It doesn't work.

Then I decided to use Montain Lion bridging infrastacture and bridge nativly via kernel. ( Mountain Lion support that)

 

ifconfig bridge0 create

ifconfig bridge0 up addm vmnet10

ifconfig bridge0 up addm tap0

 

ifconfig bridge1 create

ifconfig bridge1 up addm vmnet11

ifconfig bridge1 up addm tap0

 

The problem with that solution as soon as you 

ifconfig bridge1 up addm vmnet11 -- it leads to kernel crash ( I open a case already)

 

An example

ifconfig bridge1 create

ifconfig bridge1 up addm tap0

ifconfig bridge1 up addm tap1

Preffectly fine and it does bridging between tap0 and tap 1 interface.

any other alternative ideas how I can do that.

 

I can't use VLAN interface since VLAN interface has to be mapped to physical interface i.e eth0

 

Fusion 5.0.2 latest build

Mountain Lion latest build and patched.

 

Kind Regards,

Mustafa
