Description
Forum topic:https://forums.virtualbox.org/viewtopic.php?f=6&t=100373 Host Machie: Windows 10 64bit (i9 9900K 8core) Guest Machine1: Debian 10 64bit (4core allocated) Guest Machine2: Windows 8.1 64bit
Host Machie contains Guest Machine1, and Guest Machine1 contains Guest Machine2, it's nested virtualization.
When I run Windows 8.1 64bit in Host Machie with multiple CPUs, no crash, everything is fine. But when I run Windows 8.1 64bit in Guest Machine1, I can only allocate 1 cpu, if more then 1 cpu are allocated, it will crash after I click start.
