  • 1.  VMWare ESXi NIC Driver VMXNET?

    Posted Jul 27, 2009 07:25 PM

    Hello, I am confused and need assistance. I set up VMWare ESXi 4 on my computer and it only recognizes one nic card, How do I force the VMWARE server to use the VMXNet driver instead of e1000? I want it to use the VMXNET driver for all connections that use the VMWARE server whether I am in Vsphere management or have A VM converting

    I dont have any VMs set up yet because when I try to convert a workstation to the VM it takes over an hour and only gets transfer speeds of about 7-10 Mbits per second even though there is only one 100MB switch with only the VMWare server connected to it and the workstation. I show all Nics as connected at full duplex 100Mbits

    The 'flex' driver replaced this drive, and E1000 is higher performance. Incidentally if you upgrade that VM to version 7 you will get another higher level NIC to use as well. E1000 will be adequate for what you need.

    Those 'vmxnet' drivers are just 10/100 drivers but it's not really a driver in the VM, it's just backwards compatible, which the E1000 does also.

    Also you are doing a conversion those conversions take place on the Service Console NIC. You can't adjust that. The driver you are referring to is what the VM see's when it starts.

    If your speeds are slow, that is because of your disk drive NOT Network throughput... It's only as fast as the slowest link, in this case the drives must be slowing you down.

    And one more thing 10/100 the FASTEST speed you can achieve on your best day is 10 Mb/s. 12.5 is fastest possible, but that's not including overhead, so 7-10 is about all you can expect... Gig can give you 100 Mb/s.
