I'm using VirtualBox Version 5.2.6 r120293 (Qt5.6.1).

Guest OS: Windows 7 Ultimate (32-bit)
Host OS: CentOS 7

I tried enabling bidirectional clipboard by going to Settings -> General -> Advanced and selecting Bidirectional form the dropdown menu for shared clipboard.

enter image description here

Then I restarted the machine. But it wasn't working.

I have already tried removing and adding the VM to the machine list. But the problem persists.

Any help would be appreciated.

    Have you installed the Guest Additions on the Windows 7 guest? – n8te Feb 8 '18 at 7:21
  • @n8te I don't think so. Can you guide me to it? – Bilesh Ganguly Feb 8 '18 at 7:24

    The guest additions are required to be able to use the bidirectional clipboard so that should be the cause of your issue if you don't remember installing it. See here. – n8te Feb 8 '18 at 7:27

    Unfortunately, I can't write an answer. But I've had the same issue with Guest Additions 6.1.4. The extension is buggy, so there is no (easy) solution, but as a workaround, just downgrade to the last version. In my case, it just worked after I've downloaded GA 6.1.2. Now I can work as I'm used to and wait for the bug to be fixed. – dajood Mar 15 at 15:08

You need to add extension pack for you virtualbox

  1. Open https://download.virtualbox.org/virtualbox and open your Virtualbox version
  2. Download Oracle_VM_VirtualBox_Extension_Pack.vbox-extpack.
  3. Open Virtualbox VM Manager
  4. In File->Preferences, Select Extension
  5. Now add extension by browsing to download location

    Seems broken in 6.1.4... can't get it to work with Kali Linux rolling. Additions installed version 6.1.4 from APT repo. Something broke in the last few months. – Sean Aitken Mar 13 at 5:09

    @devman I have virtual box version 6.1.4 but installed this version of iso file, install it in your vm maybe this works for you either. After installation restart virtual box and also keep in mind that it will not share files in clip board! it only shares text as much as i saw. – Amin Nadimi Mar 31 at 10:09

This answer assumes:

  1. VBox extension pack is installed and current.
  2. VBox guest additions are installed and current.

There is a suggestion in the comments to downgrade the guest additions in order to get the shared clipboard working. Although that may work, I solved this by taking the opposite approach. Unfortunately, if you're dealing with a new version of Virtualbox, full guest support may not quite be available. You can actually download and install guest additions that are newer than the bundled or released version.

Head to VirtualBox test builds, and in the top table, you will find the latest version of the guest additions. Compare your revision with the version listed, if it's newer simply download and install it.

The guest additions are specifically what provide shared clipboard support. Take a look at the virtualbox documentation to learn what other functionality they provide.

  • I had the extension pack, but was missing the guest additions. Adding that resolved this issue for me. – Adam Howell Jun 4 at 16:12
