  • 1.  What is the maximum number of vNICs on a vSphere VM?

    Posted Jul 10, 2009 07:05 PM

    The configuration maximums says 10, but I can only add 4. Hardware 7 seems to have the same limitations as hardware 4:

    6 virtual PCI slots, one taken by the video card, 5 available for vSCSI controllers and vNICs, no more than 4 max of one type of the other. The configuration maximum guide can't be wrong can it? Or am I missing something????

    Are you sure the hardware has been upgraded - I have had no problems adding more than 4 vnics with a VM that has upgraded hardware -

    That was the problem. I created about a dozen HW 7's and 1 HW 4 for testing purposes. The one I randomly selected to add nics to was the HW 4 one. Thanks. When editing the settings of a VM, the HW version is in the upper right corner below the x close box widget.

    As Wienstien5 says are you absolutely certain that the VM you are attempting to install more that 4 NIC is has been upgraded to version 7 hardware??? verify by checking the Hardware version level in the VMX file.

    if the hardware level is at 7 the following line should be present

    virtualHW.version = "7"

    else it would say

    virtualHW.version = "4"
