I have a client with two VMW hosts with local disks (so think no HA). Each host has a front end application server on them and both connect to the same back end box. The goal is to load balance the two front end servers.
I added the NLB feature to both MS 2008r2 VMs. When I enable it on VM1 and add VM1 to the cluster (thus creating the VIP and adding it to the VM1), VM1 loses all network connectivity. It cannot even ping the gateway at this point.
I figured/assumed something may be blocking it within the vswitch. There is NO port security on the physical switch.
