Everything is great (simple installer, mouse driver, etc.), but after the installation and reboot, synthetic network adapters cannot be detected. There is only a loopback (lo) adapter after running ifconfig. This occurs on IC 3.1/CentOS 6.0 too. Can anyone give some hints to activate the synthetic network adapter? Thanks in advance.
