hi
when we do a ./configure for qemu
there is:
target list i386-user arm-user armeb-user sparc-user ppc-user
i386-softmmu ppc-softmmu sparc-softmmu x86_64-softmmu
for a x86 machine, what is the best for performance?
i386-user or i386-softmmu
thanks

i386-user.
These are two different things the -user emulation only emulates a linux
userspace. The -softmmu emulation emulates a complete system.

No, you need i386-softmmu to run a whole virtual machine. If you use the CVS
version of QEmu, you can also use the KQemu accelerator module to speed this
up.
If you wanted to (for instance) run i386 binaries on a PPC Linux host, you'd
use i386-user to emulate the x86 Linux userspace without having to run a
whole virtual i386 machine.
Cheers,
Mark
