I created a new VM via the “New virtual machine" wizard at my ESXi 4.1 server, after configuring the correct network settings and added some disks I started the VM.. but received this warning:

Insufficient video RAM. The maximum resolution of the virtual machine will be limited to 1672×1254. To use the configured maximum resolution of 2560×1600, increase the amount of video RAM allocated to this virtual machine by setting svga.vramSize="16384000" in the virtual machine’s configuration file.

Solution:

- Edit the VM settings

- Select: Video card

- Select: “Auto-detect video settings”

- Power on your VM… and it’s working
