I also noticed that on my new machine (Windows 10 on a Skylake CPU), this issue does not occur.

Indeed, as described in the ticket, the user has a 2009 MacBook Pro, which would most likely have a Core 2 Duo CPU. I am not able to test this out to see if it works, because I am in the process of decommissioning my Mac Pro. Unchecking Nested Paging resolves the issue. These CPU's are essentially Core 2 Quad's, and thus don't have Nested Paging support (just the original VT-x). The Mac I experienced the issue on was a 2008 Mac Pro, which has dual Xeon E5462 CPU's. I just recently had a thought about why this issue is occurring in 5.1.x, and not in 5.0.x and earlier. I had been experiencing the same issue, as described in this thread which I posted a while back: Sep 2016, 16:00Ĭame across this thread again. I'll keep an eye out on those tickets.ĮDIT: Is there an older version of VirtualBox (for OS X) that may have better success in the meantime? BrettR Posts: 5 Joined: 9.

I haven't installed any other software beyond Windows Updates so not sure why the VERR_IEM_INSTR_NOT_IMPLEMENTED exception is occurring.

#Virtualbox mac os on windows 7 install

I finished installing all of the Windows Updates, experienced more VirtualBox fatal errors, installed Guest Additions, didn't install any other software, and would experience fatal errors after some period of Guest uptime.

I have the ISO mounted still since I had just installed Windows 7 & immediately went to installing Windows Updates.Īs far as the stability problems and when they're occurring, on my 1st install of Windows I would just close out the VirtualBox fatal errors when they occurred and start Windows 7 again. Why do you still have the installer ISO mounted in the VM? Are you still trying to install Win7? Why? If you are having stability problems with an installed Win7 then we need to see evidence for that, rather than any peripheral problems you are having reinstalling the OS. There have been a few tickets raised about this already, so I suggest that you keep track of those.

I've tried to include all relevant information, please advise if additional is required. I've attempted to find out if anybody else is experiencing a similar issue but haven't come up with anything. I am running VirtualBox version 5.1.4 r110228 on OS X 10.11.6 El Capitan.ĭuring initial virtual machine setup I don't modify any of the default settings except available RAM from 512MB to 4096MB. The ISO is an official Microsoft Windows 7 Professional SP1 圆4 disk image and my Product Key is genuine. I have had several hours of uptime in the Windows 7 guest before the fault. 2 of the 3 times this has occurred while installing the initial round of Windows Updates i.e.

I receive an error message from VirtualBox in OS X that a fault was experienced and the virtual machine needs to shut down. I have removed the Windows 7 virtual machine and installed a new machine from scratch 3 times - experienced this instability each time. I'm experiencing an issue with my Windows 7 guest not running stably on an OS X host.
