Try installing additions and Mount share folder under VirtualBox fedora21

The process of installing this additions can basically refer to http://gamblisfx.com/how-to-install-virtualbox-guest-additions-on-fedora-21/

One copy.

1. Update the kernel first

Yum Update kernel*

2. Restart

Reboot

3. Install kernel headers, etc.

This step is critical, because it has been a failure here several times before. Without seeing this article before, it is estimated that there is less dkms (although I actually do not understand what this is), but it works.

Yum Install kernel-headers kernel-devel dkms

4. Install the additions from the VirtualBox "equipment"

5. Reboot

6. Mount shared folder

Before this, the name of the shared folder was directly share, and then protocol error occurred on Mount, so refer to http://stackoverflow.com/questions/22342028/ How-to-mount-a-virtualbox-shared-folder

, changed the name to Linux_share, and succeeded. After a few documents, said that the name of the folder can not be very special, it is estimated that the previous share is exactly the same as the built-in conflict.

Mount-t vboxsf Linux_share/mnt/bdshare
