Some day it may be useful without KVM/KQEMU, but not for a long

It is not. I tried to be clear about it in my post. Sorry for not being
clearer.
Ok now understood.
And even with them there are some instructions that can't be accesib

This was covered on this list recen
Is it means qemu simulate 8x smp in a single-thread,and the 8 virtual cpus
cannot excute dynamic translation parallel?
If use a single-thread simulate a virtual cpu,maybe the simulated cpus can
excute parallel.

I don't see in what is it useful without KVM/KQEMU.
And even with them there are some instructions that can't be accesible
without KQEMU/KVM prepared for them.
And, the -cpu option, should be enabled in x86 and x86_64 to
enable/disable emulation of instructions (and them cpuid adjusted to

It's not a typo. The short story is that there are two CPUID feature
registers - 1/EDX and 0x8001/EDX - that differ slightly. The later one
was first used by AMD CPUs and mostly enhanced by adding new features to
processors from the said company (3DNow and such). The first one was
introduced by
Hi,
the performance registers aren't implemented on QEMU.

As with Take 1 of this patch, its purpose is to expose host CPU features to
guests. It proved rather helpful to KVM in various benchmarks, and it should
similarly speed kqemu up. Note that it does not extend the set of emulated
opcodes, only exposes what's supported by the host CPU.
