This is a real pity: VMWare Fusion is AFAIK the only stable desktop virtualisation app for OS X.<p>It&#x27;s competitor, VirtualBox has the honour of being the only piece of software that &#x27;taints&#x27; the Linux kernel, not because it&#x27;s proprietary (VirtualBox is OSS) but because it&#x27;s <i>that poor quality</i> that the Linux kernel maintainers don&#x27;t want to support it.
