Even if the virtual machine runs a supported operating system, the System Selection page of the guest installation wizard launched using the vSphere Client menu displays a non-supported operating system icon.
This situation occurs if you run the installation wizard from the vSphere Client menu immediately after:
The virtual machine is powered on
Reverting the virtual machine snapshot
The wizard shows the non-supported operating system icon for the virtual machine due to the delay in retrieving the virtual machine operating system details.
Workaround: Wait for a certain time lapse after you power on or revert the snapshot of a virtual machine and then proceed to install the guest components.
