Hi, I'm trying to boot a nested VM (L2) using qemu with the "-overcommit cpu-pm=on" flag on both L1 and L2 (I want to allow the mwait instruction in L2 without VM-exits). The host (L0) is a haswell cpu, and L0, L1 and L2 run on Linux 4.18 (AFAIR I'm using rc4). The net result is that L2 fails to detect the other cores at boot time. Is this a known bug? Lacking some HW support? Thanks, Lluís
