Hi there, I'm currently using qemu-system-x86_64 (from cvs) to do Xen development for the x86_64 architecture. I find that x86_64 emulation in qemu works pretty well as long as I use a non-smp x86_64 linux kernel and ia32 user space together with CONFIG_IA32_EMULATION.
Unfortunately, if I run the Xen hypervisor (x86_64) together with a dom0 kernel (x86_64) configured with CONFIG_IA32_EMULATION, then my ia32 user space code segfaults in qemu but runs ok on real hardware. Vanilla kernel (x86_64) configured with CONFIG_IA32_EMULATION works well in qemu with my ia32 user space code though. I'm quite busy right now, but if some hacker experienced with x86_64 qemu wants to improve the x86_64 emulation, now is a golden opportunity. I have binaries and source code that might be useful.
