Like you also stated, some questions are mentioned (like Compiz and 3D games) and some aren't (like the MAC OSX EULA). It does have a link to Wikipedia stating what VBox really is for kind of hypervisor.
Forum Moderators wrote:Q: I want to make my Windows guest a member of a Windows domain. Can I do this?
A: Perhaps the simplest approach is to use a bridged network. However, at least one member has reported getting this working with NAT. See Windows XP and Active directory GPO for more details.
Forum Moderators wrote:Q: I am running Linux and my kernel has just been upgraded. Do I need to do anything?
A: VirtualBox links its device drivers against the kernel during installation. The drivers link into addresses inside the kernel. The correct addresses may change when your kernel is upgraded, and as a result VirtualBox can start to cause otherwise inexplicable errors. After kernel upgrade it is always sensible to relink your kernel drivers. This is by running vboxdrv with the setup option. The command that you will therefore typically run is sudo /etc/init.d/vboxdrv setup.
Forum Moderators wrote:Q: I have set up a VM with NAT networking, but it can't access internet while my Host system can.
A: NAT only translates TCP or UDP. One of the common reasons is that your task requires another IP protocol; for example ping relies on ICMP which is not translated. Some VPN protocols also use GRE which is also not translated.
Another common issues is that the DNS relay within the VirtualBox VMM only forwards all DNS queries to the first configured DNS server known to the host and does not search the entire DNS server list. If this DNS server is offline the hot will fail-over to the second server on the DNS list, etc., but the guest will effectively loose DNS. You can test this by checking to see if you can browse by IP from the guest (e.g. http://184.108.40.206/ gives you google) then it is a DNS problem. To avoid this problem you need to manually configure DNS on your guest OS. In the case of Linux guests see Can't connect to the internet for further discussion.
Q: Can I use 64-bit Guests on VirtualBox?
A: Yes, if your CPU has 64-bits too and supports the hardware virtualization extensions.
You need to check the "Enable VT-x/AMD-V" checkbox on the Advanced tab of you VM general options. For some server versions you also need to activate the "Enable PAE/NX" checkbox, and also some Linux Kernels under certain AMD Processors (Like Barcelona and Phenom) require the "Enable IO APIC" to be checked too.

Q: I get the error "PIIX3 cannot attach drive to the Secondary Master." when I start my VM. How do I solve this?
A: VB is not able to mount the CD for the VM. Release the ISO or physical drive from the VM settings. If you can't do that, edit the <machine>.xml file and remove the attached file/device. It looks like this, remove the line in the middle.
