title: Encountered Vagrant Up error on MacOs Big Sur Upgrade
body: <p>I just upgraded my mac OS from Catalina to Big Sur. My vagrant used to be working normally before and then I encountered this issue. (Vagrant version: 2.2.13)</p>
  <pre><code>There was an error while executing `VBoxManage`, a CLI used by Vagrant
  for controlling VirtualBox. The command and stderr is shown below.
  
  Command: [&quot;hostonlyif&quot;, &quot;create&quot;]
  
  Stderr: 0%...
  Progress state: NS_ERROR_FAILURE
  VBoxManage: error: Failed to create the host-only adapter
  VBoxManage: error: VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory
  VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component HostNetworkInterfaceWrap, interface IHostNetworkInterface
  VBoxManage: error: Context: &quot;RTEXITCODE handleCreate(HandlerArg *)&quot; at line 95 of file VBoxManageHostonly.cpp
  </code></pre>
  <p>When I tried to start it manually on the VirtualBox this is the return message:</p>
  <pre><code>Kernel driver not installed (rc=-1908)
  
  Make sure the kernel module has been loaded successfully.
  
  where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT. 
  </code></pre>
  <p>Does anyone have a clue on how to fix this issue?</p>
