[one-users] DHCP and OpenNebula

Fri Jul 12 11:38:09 PDT 2013

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...
