21412,Virtualbox + Hyper-V + 1GB Paging doesn't seem to be supported?,Evan Teran,,"I have a toy OS in which I use 1GB pages. 

The hardware supports 1GB. 
It works correctly on my Linux machine within VirtualBox. 
It works correctly on windows when Hyper-V is disabled.
It works correctly on windows using their Hyper-V VM manager.
It works correctly in qemu.

My conclusion so far is that the specific combination of VirtualBox + Hyper-V + 1GB paging is simply not yet supported correctly.

The result is a triple fault the moment the page is accessed for any reason. I'm not on my development machine at the moment, but I will post a log and a bootable ISO demonstrating the issue as soon as I can.

I'd definitely prefer to use VirtualBox for this as the Hyper-V VMs are quite limited.

Thanks!",defect,new,other,VirtualBox-7.0.4,,,,other,Windows
