title: Virtualbox running on VMWare VM on ESXi
body: <p>I am trying to run my Chef/Kitchen tests that use Vagrant/Virtualbox on an ESXi VMWare cluster guest to test cookbook integration.  I will likely move to a VMWare version for Kitchen/Vagrant and remove the Virtualbox portion at some point but would like to see this work first.</p>
  
  <p>I have the virtualization support turned on in the VM so it does function, but it is excruciatingly slow.  Where the full converge on my desktop is done in under 4 minutes, it takes nearly 40 minutes in the VM.  Checking perfomance on the VMWare VM and it seems acceptable, but the VirtualBox VM inside it has very high Hardware Interrupt service.  All other metrics seem to be about average.  Where HI rarely gets about 1-2 under normal systems it is steady >30 even while idle in the Virtualbox guest and often above 50.</p>
  
  <p>Any ideas on what to look for or magic settings I may have missed?</p>
