Vm interface speed is shown as 10G when I have only 1G Adapter in my host

Can anyone clarify me how I could see VM interface speed as 10G when I have only 1G Adapter in my host? I am using VMXNET3 driver in my virtual machine.

Light reflects against objects and you see it?
You still get 10GbE between hosts on same ESXi
If you connect 10 computers to 128kbps ISDN line do they all magically drop the speed of LAN connection?

Because the Host Hardware and Guest Hardware are different.

The Hardware in the VM is VIRTUAL!

e.g. the VMXNET3 interface is a 10GBe virtual aware virtual network interface, and the E1000 is a legacy 1GBe interface.

This is 10GBe connected to the vSwitch. The vSwitch is the connected to the uplink (vmnic the host at 1GBe)

E1000 in the VM, is not the same interface as in the host.

Do not confuse physical hardware in the host, with virtual hardware in the VM.

e.g. the VM may have a LSI SCSI Storage Controller, but you host may have a very different storage controller!

You are trying to compare apples and pears!

Thanks for your comments. Now i understood that it shows the speed of the interface between the VM and the vswitch inside ESXI. Is there any document from VMWARE/VMXNET3 to explaing this behaviour?
