Windows 8 Pro comes with Microsoft's Hyper-V virtualization platform. If you have new and beefy PC, it is likely that the CPU supports Hyper-V (Celeron owners, don't bother). Everybody needs couple of Linuxes running inside your Windows, right? At least I do.
Getting the newly installed CentOS 6.3 to support networking is a bitch. After the CentOS installation finishes you're left on a virtual console screen with little possibilities of getting to outside world from your sandbox. The Wikipedia article about the subject reveals, that Microsoft had to submit their code into Linux kernel to comply with GPL license requirements. But still, CentOS 6.3 has kernel 2.6.32, but the much needed Hyper-V kernel modules are not available. Darn!
It took me an hour of Googling around, before I ended on Microsoft web page titled Linux Integration Services Version 3.4 for Hyper-V. I got the .ISO image, mounted it into my virtual Linux and run the install script. Yesh! The script managed to get my NIC to appear as eth0. After that it was just a breeze to get it configured with DHCP-client. It's a pity that nobody clearly documents this part of the installation process. People could save hours of work if somebody said to go get them.
Apparently new Linux distros come with Hyper-V drivers built in. In my case I need to run the same OS than my production server does.
