That is how we used to do it, but using two distinct vswitches, one for vmotion on vlanX, and the other for management on vlanY.
I thought the benefit of the yellow-bricks configuration was that it was redundant in that if one vmnic goes down the standby kicks in and takes over.
If we were to use different vlans how would that work? once it failed over to the standby vmnic wouldn't that cause it to get a different IP address on that new vlan? or am I missing something?
