title: nested virtualization: shutting down L2 kills L1
body: <p>I am looking to run an Linux VM (L2) within a GCE Ubuntu instance (L1). I am following the steps described at:</p>
  
  <p><a href="https://cloud.google.com/compute/docs/instances/enable-nested-virtualization-vm-instances" rel="nofollow noreferrer">Nested Virtualization on GCP</a></p>
  
  <p>Everything works just fine until I shut down or terminate the L2 instance. Once the L2 instance is shut down, the L1 goes into a kernel panic. Has anyone seen this? Any ideas?</p>
  
  <p>I tried exactly the same thing on Microsoft Azure, and it works just fine.</p>
  
  <p>Thanks,</p>
