| 1 | | Frank is telling you that your CPU is old and it's missing an important virtualization feature (nested paging) which could make your Windows 10 VM to run unstable. Running a VM without nested paging means a lower performance for the guest OS, in all cases. With your current platform (socket775/771), this feature is not available.[[br]] On the other hand, the Windows 10 OS guest (from its perspective) only cares about the missing cmpxchg16b feature, which you can enable by changing the VM OS version from Windows 7 to Windows 10, from the VM settings. That's because VirtualBox manages your CPU features, not all of them are passed to the guest OS. |
