| Configure VB's centOS 5 "Host-Only" network | |
| 1 - Config virtual machine, add a "host-only" network | |
| 2 - Windows sees "Virtualbox Host-Only" network as a public network, so it blocks access. | |
| Follow to fix: | |
| 1. Open regedit and navigate to HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318} | |
| 2. Browse through the subkeys (named 0000, 0001, etc) until you find the subkey containing the virtualbox network adapter, this is the one where the “DriverDesc” key has “VirtualBox Host-Only Ethernet Adapter” as value. | |
