13102	Mac OS X host kernel panics when nested paging is enabled on Win 8.1 guest.	Alex Markley		"Team,

I have had great success with VirtualBox over the years for my personal use with multiple guest OSs on Linux hosts. The other day I attempted to migrate to an OS X host. (10.9.3 Mavericks with VirtualBox 4.3.12)

All of my virtual machines seem to work great, but my Windows 8.1 virtual machine always causes my host operating system to kernel panic. This has happened four times and always within minutes of booting the guest.

However, if I uncheck ""Enable Nested Paging"" the guest runs smoothly and the host does not panic.

To be clear I have definitely updated the guest tools.

I have attached some host kernel panic backtraces for reference. Please let me know what else I can do to help troubleshoot this. :)

Thanks!"	defect	closed	VMM	VirtualBox 4.3.12	obsolete	mavericks crash kernel panic nested paging		Windows	Mac OS X
