Including a screenshot to show the ESX HW settings are correct for the NIC as well
Does anyone else have this issues?

The windows VM boots up, and looking at the edit settings in vSphere , for the created host one-26 , I see an e1000 NIC with the MAC created above. However when I log into the OS, it says no network card detected

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

Spoke too soon ---
Yes the NIC is now visible to the OS, but it is no longer trying to join the VM Network , and is instead trying to create a one-pg-3 (for network3) which does not exist on the ESXi hosts
I would assume this means it cannot create a virtual network on the ESX hosts, and using the dummy network definition adds the NIC on the already created virtual network
But as noted in previous comments - there is no ability to find the NIC with the dummy network defined
Hoping there is information about not being able to create the network in the ESXi hosts that could resolve this.

RESOLVED!!!
When setting up the networks, I was following some steps for DHCP that suggested using the Dummy driver for networking and vmware with dhcp
I removed the hosts from the cluster and re-added them , but defined the network as vmware and now it recognizes the network card!!

Hello again,
As noted below I can clone a windows VMDK - and buid it with an e1000 network card attached (screenshots showing the HW attached in vSphere attached)
I tried to modify the clone image to have the drivers from Intel(r) Pro 1000/MT on the file, but they don't install because they don't find the network card attached
See screen shots for what the network card looks like on a clean VM clone

Hello -
I found that the NIC definition goes into the onetemplate template settings that I am using and it is now adding the NIC to the hardware as e1000
However when the Windows VM boots - it does not see ANY hardware NIC's
I have tried the following steps
* Removed NIC and RE-added via vSphere
* Re-installed vmwaretools (it is already installed in the cloned VM, but couldn't hurt)
* Removed NIC and Re-added it again via vSphere
Still no luck in finding the hardware NIC inside the VM - any one else experience this issue?

I tried to use this template to build a VM with a Network NIC -
Does this look correct for NIC assignment within VMware?
NAME="myvm-win"
CPU=1
MEMORY=512
DISK=[ IMAGE_ID=13 ]
NIC=[NETWORK_ID="1",MODEL="E1000"]
Has anyone else done NIC assignments with Windows Deployments in Vmware? I can get the Windows VM up and running , the NIC shows up in the settings (as flexible) with the sunstone GUI
But when I open the VM it has no NIC's inside of it? I choose the dummy network driver - maybe that's not what I needed?

So -
I configured a Virtual Network in OpenNebula GUI (sunstone) and it now adds NIC settings to the Windows VM
ethernet0.present = "true"
ethernet0.networkName = "VM Network"
ethernet0.connectionType = "bridged"
ethernet0.addressType = "static"
ethernet0.address = "02:00:c0:a8:fb:01"
ethernet0.checkMACAddress = "false"
But it does not set the
ethernet0.virtualDev ="{e1000|vmxnet3|flexible}" so the VM does not see any NICs

It works exactly like a physical server- if there is network visibility (same vlan or default bridge) the booted VM will get its address from DHCP. We use this configuration (thus ignoring the opennebula-assigned IP) in several customers' networks, especially when the VM cones from virtualization of user desktops.

But in that case, I would be assigning IP's to hosts instead of them booting up and just using DHCP to get the IP address
I want to just assign the NIC and let the OS obtain an IP from DHCP instead, on system boot.
Still reading the documentation, but not seeing a method for it yet.

>From what I understand, OpenNebula encodes the IP in the MAC, for example, the VM with assigned IP 10.0.0.2 would get a MAC 02:00:0a:00:00:02. Just create an IP:MAC list for the DHCP server and it will work.
host a10-0-0-1 { hardware ethernet 02:00:0a:00:00:01; fixed address 10.0.0.1; }
host a10-0-0-2 { hardware ethernet 02:00:0a:00:00:02; fixed address 10.0.0.2; }
and so on...
