Configuration of VirtualBox data space in Linux

This section describes how to mount the host folder in Linux in VirtualBox to share files between virtual machines and hosts.

Environment: Oracle VM Virtualbox 4.0.10 + CentOS 6.0

1. Install VirtualBox Guest Addition in CentOS

On the current virtual machine interface, click "device"-"Assign Optical Drive"-"Choose a virtual CS/DVD ..."

Open the installation folder of VirtualBox, which defaults to "C: \ Program Files \ Oracle \ VirtualBox", and select "VBoxGuestAdditions. iso" for mounting.

Open the CentOS Super Terminal and run the following command to install VirtualBox Guest Addition.

[Root @ Slyar ~] # Mount/dev/cdrom/mnt
Mount: block device/dev/sr0 is write-protected, mounting read-only
[Root @ Slyar ~] #/Mnt/VBoxLinuxAdditions. run

The first is to mount the disc to/mnt, and the second is to install the disc. Wait until the installation is complete. (If you do not have X desktops like me, the last one may be Failed without any impact)

2. Configure the Data Space

On the current virtual machine interface, click "device"-"allocate data space". In the pop-up interface, add a temporary allocation (fixed allocation is also acceptable, not called)

"Data space location" is your shared folder. Remember the data space name. Do not select "Read-Only allocation" or "Auto-mount ".

3. Restart the Operating System

[Root @ Slyar ~] # Reboot

4. Mount the shared data space

After starting the system, you can use the following command to mount the data space (assuming the data space name is slyar) to/mnt, where "-w" is writable. to read-only, you can change it to "-r"

[Root @ Slyar ~] # Mount. vboxsf-w slyar/mnt

5. unexpected circumstances

If the disk cannot be mounted due to an accident, you can directly access the following directory to use the shared space.

[Root @ Slyar ~] # Cd/media
[Root @ Slyar media] # ls-l
Total usage 0
Drwxrwx --- 1 root vboxsf 0 July 15 15:13 sf_SLYAR

"Sf_SLYAR" is the shared data space folder.

PS. You can try to re-mount the vboxsf module:

[Root @ Slyar ~] # Modprobe vboxvsf
