VMWare, and Network management between the host and VM
I noticed that I get much higher network usage in the VM than in the host, something like:
Host: 20,000 KBps
VM: 90,000 KBps
In KVM, (some time ago when I did that, so the current version of KVM may no longer do that) it was always the opposite, I would have gotten something like:
Host: 180,000 KBps
VM: 90,000 KBps
Because the host essentially did a memcpy from the adapter output to the VM.
Why does that not happen in VMWare, how does VMWare manage its network usage between the host and the VM.

Is the vm communicating with other vms on the same host?
