I'm sure Qemu without > accelerator will work but is there something in accelerator that won't work > with Xen modified kernel. IIRC, the binary portion of the accelerator module uses some instructions (e.g. sti, cli) that can't be directly executed under Xen. Although emulation for them may now be in the unstable tree, the accelerator probably won't work in -stable or -testing. Such a configuration would be rather useful however. Those who are more knowledgable about QEmu can probably shed more light on this than I, however. Cheers, Mark
