First, at least one of the kernel hardening boot parameters somehow messes with the CPU detection on the host (in my case, a quadcore showing only two physical cores, the virtual cores being ignored), which heavily decreases performances. I need to further investigate this issue to find out which specific boot parameter(s) causes that.
