1 Hi Vinícius,

3 The first thing that springs to mind to check is have you got hardware
4 virtualisation enabled? I notice your launch command includes -no-kvm
5 as an argument - doesn't that disable kvm and result in a fallback to
6 qemu? Try running with kvm enabled and I suspect your performance will
7 be approximately 10x better.

9 Just a couple of thoughts,
