[one-users] DHCP and OpenNebula

Fri Jul 12 16:05:25 PDT 2013

Hi Michael

Just to double check. Could it be that the name of the vSwitch/port groups
in your ESX are not properly set in the Virtual Network template in
opennebula?.

You should be able to use the dummy drivers as long as the BRIDGE attribute
of the virtual network matches an existing **port group** in the ESX's. I
guess that if you try to add a NIC to a non exisiting port group it does
not show up in the guest?

If you want to use the dynamic mode (vmware network) the BRIDGE is the
**vSwitch** name in the ESX, where a dynamic port group will be created.

Cheers

Ruben
