Can't share one NIC card on Hyper-V running on windows 8

Hi
I have  servers.
One is running windows 2008, one windows 2003 standard and one Windows 2012 with Exchange 2013.
I took an image with Acronis on the Win 2003 and 2008 and covert the image to a vhd file.
I install Hyper V on Windows 8 entreprise just temporary for testing and I installed from scratch windows 2012 with exchange 2013 as a DC on a VM
Then I create a virtual machine for the win 2008 and the win 2003 server and assign the vhd that I convert from Acronis.
The windows 8 host has 16 gig of ram but only 1 NIC card so I enable the OS sharing under the virtual switch manager.
My problem is that if I start more than one server at the time it will stay for over 40 minutes saying please wait until it get to the CTR ALT DEL screen under the windows 2012 and about the same for the other. The servers are also very slow. Once logon it has no network connection. If I turn on one server at the time I do not have this problem.
Looks like they can't share the same NIC card.
Each server has 4 gig of Ram assign.
Any idea how I can make all 3 servers plus the host to use the same NIC card without any problems.
If I keep rebooting sometimes I'm able to have 2 servers working but I have to do it so many times.

Did you install the integration services for each VM? Because this is the only way to install the "proper drivers" inside the VMs.

Yes I installed the integration Services.
Now I can't even get it working with one server.
For some reason the server does not communicate with the virtual adapter.
could that be because is running under windows 8 hyper v?
the host is running an I7 processor with 16 gig ram and gigabit Nic.

I would think you have enough resources for a few VMs.

Just don't understand why the windows 2012 virtual server take over 30 minutes to load and it keep showing Wait.
Well I will play a little bit with then I will try install those VM on a windows 2012 host and see if it makes any difference.
I will also try to clear the Arp see if it makes any difference.
I had to do the same on the production win 2003 DC after I broth it back online.
Both DC having the same IP and name was online for a few minutes at the same time because I did not realized than the production one was not off when I brought the lab one up.
