Right, dom0 is a Xen3 Debian. OK, but that's strange, I read the opposite advice from you and Eric Van Hensbergen : http://9fans.net/archive/2007/04/152 OK, it's 5 years old... I wasn't aware that qemu/kvm did such progresses... what make this huge difference? On the other hand, since 2009, I tried a lot Plan 9 over qemu+kqemu, then switched to kvm (Intel vmx). Even if I didn't quantified the benefits of Xen3, I really felt it gave me best perfs for both disk access (fossil+venti) and when running as a terminal (graphics). But kvm is to me far more simpler to setup (no dom0) and run. Nicolas
