Title:
  VM failed to start in nested virtualization with error "KVM: entry
  failed, hardware error 0x0"

Status in QEMU:
  Expired

Bug description:
  Hi,

  I have 3 ubuntu nodes provisioned by IaaS. 
  Then I tried to launch VM again in my ubuntu nodes.
  It's a little strange that VM could be started successfully in two nodes. 
  And always failed in one nodes with error "KVM: entry failed, hardware error 
0x0". 

  When using virsh to resume the VM, it failed with following error,
  virsh # list
   Id   Name                State
  ----------------------------------
   1    default_vm-cirros   paused

  virsh # resume default_vm-cirros
  error: Failed to resume domain default_vm-cirros
  error: internal error: unable to execute QEMU command 'cont': Resetting the 
Virtual Machine is required

  
  The detailed log from /var/log/libvirt/qemu/default_vm-cirros.log is as below.
