Trying to boot with the guest in 32bit mode - I see a black window ( that never progresses to the VirtualBox bios/efi boot screen ) - When I reboot the guest into x64 bit mode, I can then boot the guest slightly farther ( the window resizes, the efi/bios boot screen is displayed it appears that OSX tries to load), but it reports that it cannot find the 'mach_kernel.mkext' and then kernel panics. ( Having the host in 32 or 64 bit mode, does not appear to matter. ) I'm booting the guest from an OSX Server 10.6 iso. My host system is a Core i7 MacBookPro6,2, running VirtualBox Version 3.2.8 r64453 My other host system is a MacPro4,1 running VirtualBox Version 3.2.0 r61806 - and this system has no problem installing OSX Server Snow Leopard, from this ISO. I've already tried uninstalling VBox 3.2.8 and installing 3.2.0 from the same .dmg file that was used to install VBox on the MacPro, and it didn't resolve the problem - so I'm assuming that the issue is related to my MacBookPro's ACPI or EFI.... I've included my VBox.log and some screen shots...",defect,closed,installer,VirtualBox 3.2.8,wontfix,,,OSX Server,Mac OS X
