title: How do I fix "Failed to sync vcpu reg" error?
body: <p>I'm trying to use the Intel HAX x86 emulator for Windows (8, if that matters).  I installed everything and created an AVD for the android version, and everything appears correct, but when I run it, I get this output:</p>
  
  <pre><code>Starting emulator for AVD 'x86_QVGA_Level10'
  emulator: device fd:1044
  HAX is working and emulator runs in fast virt mode
  emulator: Failed to sync vcpu reg
  emulator: Failed to sync HAX vcpu context
  </code></pre>
  
  <p>and the emulator won't run.  The significant part of this error <code>(Failed to sync vcpu reg)</code> is not mentioned ANYWHERE online, except in the <a href="http://mirror.yongbok.net/pub/linux/android/repository/external/qemu/target-i386/hax-all.c">source code for the HAX itself</a>, but I can't figure out how to make any sense of this.</p>
  
  <p>Can anyone advise about how to get past this error?  I really need to get this working, because debugging on device and in the default emulators is painfully slow.</p>
