Question
I installed esxi on a ml110g5 .The host card is 100mbps but in windows 2003 serveur VM that is limited to 10 mbps (Card detected as AMD PCnet cards that ESX). Why is that ?
Answer
Note that the network speeds reported by the guest network driver on the virtual machine do not
necessarily reflect the actual speed of the underlying physical network interface card. For example, the
vlance guest driver on a virtual machine reports a speed of 10Mbps, even if the physical card on the server
is 100Mbps or 1Gbps, because the AMD PCnet cards that ESX emulates are 10Mbps. However, ESX is not
limited to 10Mbps and transfers network packets as fast as the resources on the physical server machine
allows.
