Unable to start Fastpath?

Which virtual network adapter are you using. I suggest you use vmxnet3

Currently fastpath supports the following NIC drivers: i40e, e1000, e1000e, igb, ixgbe, vmxnet3.  If fastpath is enabled when system has no supported NICs, fastpath load will fail but system will still be fully functional without the performance enhancements provided by fastpath

Stuart, I am not sure about selection of virtual network adapter, Can you please let me know how can I confirm it?

Hi James,

please read this thread that Stuart answered sometime ago.

Its been a long time since I used Fusion but I think you need to shutdown the VM, then edit the .vmx file for the VM to change the adapter type.

ethernet*.virtualDev = "vlance" - thats the PCnet32 driver which is likely what yours has defaulted to.
ethernet*.virtualDev = "vmxnet"
ethernet*.virtualDev = "vmxnet3" - thats what you want

ethernet*.virtualDev = "e1000"
ethernet*.virtualDev = "e1000e" - a newer version of the E1000 which uses an PCI-express slot

the * is obviously a number for your adapter.

Hello Stuart, I am getting below options

virtualHW.version = "14"
pciBridge0.present = "TRUE"
pciBridge4.present = "TRUE"
pciBridge4.virtualDev = "pcieRootPort"
pciBridge4.functions = "8"
pciBridge5.present = "TRUE"
pciBridge5.virtualDev = "pcieRootPort"
pciBridge5.functions = "8"
pciBridge6.present = "TRUE"
pciBridge6.virtualDev = "pcieRootPort"
pciBridge6.functions = "8"
pciBridge7.present = "TRUE"
pciBridge7.virtualDev = "pcieRootPort"

Shall I replace pcieRootPort with vmxnet3?

Actually, I am unable to get that exact details which you have mentioned, please help me test this feature properly

James, your installation is using the pcnet32 driver by default hence why it's not listed. Simply add

ethernet*.virtualDev = "vmxnet3"

replace the * with unique number for each interface. eg ethernet0.virtualdev = "vmxnet3"

Stuart, You are my savior. Issue got resolved as per changes suggested from your end

I dont have Fusion as I said, but the fact this doesnt work when you have acceleration disabled or enabled tells me this is a straight networking issue. I would look at the overall vmware network configuration, especially how the VM is bridged to your local adapter.

Probably the first step would be to comment out the changes you just made and make sure you still have connectivity with the default driver.
