VirtualBox guest additions fail on Fedora 22

[GreyGnome]

My Windows 7 virtual machine cannot enable USB 2.0. As soon as I attempt it, I get "Invalid Settings detected". It says it requires the Oracle VM Virtualbox extension pack to be installed. However, I have installed it as requested by Virtualbox, and in the "Uninstall programs" dialog box in Windows I see that "Oracle VM Virtualbox 5.0.14 guest additions" is installed.

VirtualBox's help->About dialog shows that I am running Version 5.0.14_RPMFusion r105127.

I notice that there is a VirtualBox-guest package available- do I need it on the Linux side, even though I installed the guest additions from the .ISO downloaded by Virtualbox itself?

In any event, I cannot install the package:

Code: Select all

root@rodin ~]# dnf install VirtualBox-guest

(try to add '--allowerasing' to command line to replace conflicting packages)

You need to install the extension pack. The Guest Additions are not the same thing.

Yup, that's it. Forgot all about that thing. Thanks!
