Im having a networking issue in my new test environment - server core 2008, hyper-v.
I have 2 NICs on the hyper-v server, 1 for the host and the other is shared by 3 x VM through the usual virtual network switch.
Host has static IP and the 3 test VM's have static IP's too.
Whatever I try, I can only get external network communication through 2 of the VM's at any time.
Running constant pings from all 3 VM's, only 2 will communicate externally. It's any 2 of the 3 which will work. I can start any 2 VM's and they work, start the third, no IP connectivity. Shut them all down, start any 2 of the 3 VM's, both OK, whichever VM I start 3rd, will have no IP connectvity so its not specific to the VM's...or its specific to all of them!
As its my first server core 2008 build, im struggling to get information on the virtual network switch on the hyper-v host as it seems to be only allowing 2 connections through it.
Networking pic link below, (ignore the test2003x86 VM having 2 virtual interfaces as i've been trying different setups and additional virtual network cards to no avail).
So in the pic below, the test2003x86 and test2003x64 VM's both work fine but the test2008 VM has no external network, the interface on the VM sends packets but receives none. (test2008 was started last).
Any 2 from 3 working? Im sure hyper-v supports more than 2 VM's on its virtual network switch? Unless its a limitation on the NIC on the host (Intel CT gigabit card).
AFAIK, all 3 should be working...?
