Booting into Linux with Hyper-Threading Enabled

Details

Why do I receive a message indicating that I have double the number of CPUs on my server?

Solution

If you have Hyper-Threading enabled, then you might see an incorrect message indicating that you have double the number of CPUs on your server. This occurs only when you boot your ESX Server system into Linux. You can safely disregard this incorrect information.
