[one-users] problem with vifs

[Tino Vazquez]

Hi Angel,

There are two network models for ESX [1]

  1) Pre-defined network model: The BRIDGE of the vnet has to point to a
pre-created port group. The VMs with NICs in that vnet, will get their NICs
binded to that port group. This solution doesn't isolate one vnet from
another

  2) Dynamic network model: The BRIDGE of the vnet has to point to a
vSwitch. A port group will be created by ONE to channel all the traffic of
the VM NICs attached to this vnet. This will effectively isolates one vnet
from another. You will need the esxcli installed in the ONE front-end.

The difference between this two is that, when you create the host in ONE
with "onehost":

onehost create esx1 -i im_vmware -v vmm_vmware -n dummy       # for 1)
onehost create esx1 -i im_vmware -v vmm_vmware -n vmware       # for 2)

Hope it helps,

-Tino
