I'm trying to get the Nagios XI virtual machine working on Hyper-V (yes, I know it's not a supported config). I'm trying to get it on the network to download some packages so that I can then install the Enlightenment components and use a synthetic adapter.
I've configured the machine with a legacy adapter which is correctly recognised as eth0, and it picks up a DHCP lease, but after that I can't seem to get any traffic to traverse the network at all. The same virtual network is being used for other guest machines so I know it's working. My Linux skills are limited. Can anyone help?
EDIT: I can ping the leased address from the machine itself, but cannot ping any other address on the same subnet, nor can any other machines ping this erver.
The VM is running CentOS 6.2. Kernel 2.6.32-220.17.1.el6.i686
UPDATE 5-Jul-2012
I have set up a brand new VM on a different server using the same source VHD. This time I configured the machine using a static IP address, but the end result is the same. dmesg | grep eth
yields:
