Problem
How to enable jumbo frame support in ESXi.  I currently have a VM up and running, Server 2008, and when I set Jumbo frames to 9000, it reverts back to 1500.  I have intel nicks on the ESXi box, and I;ve seen solutions by enabling jumbo frames to the vswitches using Service console for the licensed ESX server, but since ESXi doesn’ have a service console, is there any workaround?

Solution

First  make sure that you’ve got VMWare tools installed on the Guest OS and the Network adaptor is listed as “Enhanced vmxnet” or “Flexible”

- VI Client->Inventory->Guest OS->Right click->Edit settings->Select “Network Adaptor 1″

- On the right will be the Adaptor Type
