title: Cant run virtualbox after updating mac to 12.0.1 monterey - error with host only adapter
body: <p>I'm running a virtualbox image using vagrant on mac. Everything worked fine untill I updated to the latest Mac version (12.0.1 Monterey).</p>
  <p>When I try to start up the machine using vagrant up I get the following error:</p>
  <pre><code>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>If I go into virtualbox (the mac app) and start the machine there I also get an error (just saying it failed to start the machine.
  If I go to the host network manager part of</p>
  <p>So there seems to be a problem with the host-only adapter.</p>
  <p>After some diving into it and looking through other people's problems and solutions I tried the following:</p>
  <ol>
  <li>Allowing oracle from security and privacy settings, this didn't appear however</li>
  <li>running a command that restarts virtualbox (can't find what it was anymore, sorry :/ )</li>
  <li>reinstalling virtualbox</li>
  <li>install a testbuild from virtualbox(6.1)</li>
  <li>Adding virtualbox to full disk permissions</li>
  <li>adding the following from the <a href="https://www.vagrantup.com/docs/providers/virtualbox/configuration" rel="nofollow noreferrer">vagrant documentation</a> code in the vagrantfile:</li>
  </ol>
  <pre><code>    config.vm.provider &quot;virtualbox&quot; do |v|
        v.gui = true
      end
  
  </code></pre>
  <p>Everytime I try to install virtualbox I get an error stating that the setup failed. But the icon is back again.</p>
  <p>What can this be and how can I solve this ?</p>
