title: Android emulator and virtualbox cannot run at same time
body: <p>Whenever I have Virtualbox running, I cannot start an Android emulator image (and vice versa). The error message in the AVD manager is</p>
  
  <pre><code>ioctl(KVM_CREATE_VM) failed: Device or resource busy
  ko:failed to initialize KVM
  </code></pre>
  
  <p>How can I make both run at the same time?</p>
  
  <p>That is a Ubuntu 64 bit, all involved software is of the latest released version.</p>
