If I am running VMWare server on a Linux host, and the VMs are using bridged network, will the VMs know to failover to the other NIC? I don't have a clear picture of how VMWare bridged networking actually works.

I still need to go read more about Linux bonding. My goal is to have a secondary NIC that is failover where the switches do not need to be stacked (Each nic will be connected to a different switch, the switches will be trunked). So maybe I will ask this in a second question, and it is kind of a bonus question here :-)

Works perfectly with KVM:
ethX+ethY -> bondX -> bridgeX -> VM
failover happens on the bond level, transparent to the VM

shouldn't be different, just need to use the bond alias instead of the NICs when configuring the bridge there. –  dyasny Feb 16 '10 at 15:49
    
This is how I have my VMWare Server setups configured but honestly I haven't yet tested they behave like we want. –  Keith Stokes Feb 16 '10 at 15:55
    
So I create the bond interface, then re-run configure.pl (whatever that was) and tell it to bridge to the bondX interface (ie bond0) ? –  Kyle Brandt Feb 16 '10 at 15:57
    
Not too sure about the vmware bits, I've kept away fir over a year now. but yeah, either via a script, or connect to the GUI, and set up the bridge (or v-switch?) to connect to the bondX interface as the physical NIC it should go out through –  dyasny Feb 16 '10 at 17:05
