Need help connecting my VM to the network

Posted on 2011-05-12

It’s a long story but I will try to keep it short.  The problem that I am having is that a new VM is not connecting to the network.

I currently have 1 Hypervisors (Hyper-v 2008 R2 core-install) that we purchased to move most of our app server to virtual.  It has been running 1 VM for over 3 months without issues.  I am ready to start moving more to it but I cannot get the new VMs to identify the network or even get DHCP (yes I did check the cable).  The Server has 2 NICs on it and they are both plugged in.  However one NIC does not seem to be able to get an IP address.  This is a new server so I’m hesitant to believe that the NIC that is built into the MB is bad. Nevertheless when I have the new VM use the same NIC as the VM that is working, it still does not see the network.  I have a test server with the same configuration and I have 3 VMs running using the same NIC.  What am I missing?  What am I doing wrong?

    If you have an HP ML350 G6 server, this is a know problem with hyper in windows 2008 server, what I did to get the network working in the VM is change the network card in the vm configuration. I delete the network card and add a new one in different driver emulation.

    The server where I am having the problem is a Dell PE 2900.  I did delete the network card in the VM and added a new one and it still did not work.  It is just acting as if the host is limiting the VMs to one VM per NIC.  I know that it should be working because the other is working with 3 MVs on the same NIC.

    The problem was the switch not letting the network card act as a switch. In other words it only allowed one connection.  When we changed it to see the port as a port attached to a switch, everything worked.

    I found the solution on my own.
