I have few ESXi 4.1 hosts with vCenter.
The case is in the current LAN, there is already a DHCP server.I don't want the VM in the hosts to be affected by the DHCP server.
So, I thought of putting the VM in isolated vSwitch (vSwitchB). And creating a VM (VM GW) as gateway for the VM to talk to LAN.
Is there any better approach? Can I create a distributed switch that acts like isolated vSwitch?
Thank you.
IMO - The better solution (if possible in your environment) is to put vSwitchB in a seperate vLAN. The DHCP broadcast request will not be able to get on the vLAN (broadcast domain) that the DHCP server is on. You could then configure your router/layer 3 switch to route between both vLANs as needed.
If things change later and you need these VMs to get DHCP address you could then add an ip helper to the router pointing to the DHCP server with a scope for that segment.
