Description

BIOS based Provisioned Target Devices boot slow through single IO.

Background

This symptom appears random. It may occur on a single vm boot or many, for example: five out of ten vm's may boot as expected and the remaining five may boot anywhere from 5 to 60 minutes later. After boot when the Target Device is up and running performance appears to normalize, the networking heap memory on the ESX host might show unusually lower than expected in the host logs during a provisioned guest boot.
