APPLIES TO:

• Parallels Desktop 8 for Mac
• Parallels Server Bare Metal

Symptoms

Your Mac may experience occassional crashes while running Parallels Desktop 8 or Parallels Service Bare Metal at the same time as KVM or Virtual Box.

Cause

This issue is caused by incorrectly working third-party virtualization engines that do not ensure that the virtualization state remains consistent with the state of the actual CPU.

Resolution

For KVM: 

Set the KVM module variable "vmm_exclusive" to 0.

for Virtual Box:

No workaround is available. Please try not to use Parallels Desktop and Virtual Box at the same time.
