Suppose I run QEMU on a T1000 with an 8-way CPU and I tell it to simulate 8x
SMP. WIll it spawn a separate thread for each dynamic translation activity?

No. qemu is single-threaded.

Do you have plan to multi-thread?

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.

This was covered on this list recently:
