My LXC container with windows 11 died. I've installed official version of windows 11. Here is the log:

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.

It happens quite often, what coult be the reason? And how to fix it?
