** Description changed: KVM crashes with the following error when installing Windows 11. I am able to 100% reproduce the crash. KVM: entry failed, hardware error 0x80000021 If you're running a guest on an Intel machine without unrestricted mode support, the failure can be most likely due to the guest entering an invalid state for Intel VT. For example, the guest maybe running in big real mode which is not supported on less recent Intel processors.
