Answer 1

I had exact same error today. Yesterday I've installed a few Windows updates. Commmands vagrant halt, vagrant up, vagrant reload didn't help.

What I finally did was uninstalling Virtualbox and installing newest Virtualbox version + doing same for Vagrant (because I had Vagrant that didn't support newest Virtualbox - so in some cases it wouldn't be necessary).

After restarting PC, I could run vagrant up without a problem and everything is working as yesterday.

Answer 2

I just went through the same error when trying to start a VirtualBox VM. The VM started earlier in the day and after I installed some Windows updates it stopped working. Here is what fixed it:

1. Open Control Panel, Programs, View Installed Updates.
2. Scroll down to Microsoft Windows.
3. Find the Security Update for Microsoft Windows (KB3004394).
4. Select that update, then click Uninstall at the top.
5. Reboot and VirtualBox should again be working.

I just lost an hour to this problem.
