The Host OS is openSuSE v11.1 x86_64. The Guest is WinXP, and it works well. I got this far by ignoring the error messages that had stymied me previously; VB error messages tend to be uninformative and even misleading. The problem now is that I have been unable to install the Guest Additions. Devices > Install Guest Additions returns a message informing me that it can't find the needed image file in either: /usr/share/virtualbox/VBoxGuestAdditions.iso /usr/lib/virtualbox/additions.VBoxGuestAdditions , and offering to down load it. The file was downloaded, and deposited in the .VirtualBox directory. I copied the file to the first-named locations above; it is not possible to copy it to the second, because, although there is a /usr/lib/virtualbox directory, there is no "additions" directory, and no possibility of making one, because there is a file called "additions". (The file, by the way, identifies itself as "plain text", but it is in fact binary. I have no clue what it is.) With the image file safely pasted in the one directory that will accept it, Devices > Install Guest Additions is still unable to find it.
