5829	Virtualbox and Guest Additions cannot coexist on Linux	robertr64		"    I have a dual-boot Windows and Linux partition with each one defined so that it can be either a host or guest using the VMWare-style physical disk (vmdk) setup. 
If I have both VirtualBox and Virtualbox Guest Additions installed on the Linux side,
one or the other will fail, depending on which driver is installed first. This used to work ok with Virtualbox up to 2.10 but started failing on the 3.1 build. When booting Linux from Windows, it gets a modprobe error on vboxdrv. 

vboxdrv: exports duplicate symbol RTMemExecFree (owned by vboxguest)
vboxdrv: exports duplicate symbol RTMemExecFree (owned by vboxguest)

A similar error occurs if you boot Windows from Linux. vboxdrv can't establish the network connectivity."	defect	closed	guest additions	VirtualBox 3.1.2	fixed			Linux	Windows
