VMWare ESX: Fix: "Insufficient Memory Resources" - Unable to Poweron VM

This issue affects ESX servers only.

Cause:
Server was built incorrectly and did not have sufficient swap file space allocated.

Fix:
Create and activate a second swap file.

Action:
SSH into the troubled ESX server. Verify how much free space you have on the LOCAL vmfs partition.

vdf –h

vmkfstools –k 12G /vmfs/vmfslocal/SWAP2.vsp

Now it’s time to activate:

vmfstools –w /vmfs/vmfslocal/SWAP2.vswp

You should now be able to power on your Virtual Machines.
