I created 5 vms inside vm with kvm's nested virtualization. 1 of them booted fail and showed the bluescreen. 2 of them booted successfully, ran for several minutes and showed the bluescreen.
I got different bluescreen: 1. IRQL_NOT_LESS_OR_EQUAL *** STOP: 0x0000000A (0x0000000000009007, 0x0000000000000002, 0x0000000000000000, 0xFFFFF800016CDC63) 2.

Is there any mistake? Thanks, John
