Multi-threaded emulation for QEMU

Here is a paper from last month&#x27;s CGO2017 conference, explaining the techniques more in detail: <a href="http:&#x2F;&#x2F;www.cs.columbia.edu&#x2F;~cota&#x2F;pubs&#x2F;cota_cgo17.pdf" rel="nofollow">http:&#x2F;&#x2F;www.cs.columbia.edu&#x2F;~cota&#x2F;pubs&#x2F;cota_cgo17.pdf</a>

For some reason I thought the reason that this hadn&#x27;t been implemented already was that Sony had patents on multithreaded binary translation. I guess those might have only applied to specific techniques for heterogeneous or ring-bus systems (i.e. Cell), though.

This has recently landed in upstream qemu and will be available with the 2.9 release.

does this mean one could run (without hardware support, say in aws) smp virtualization? i.e. linux on linux or windows on linux (why not just spawn another machine? because you want to have more control than what aws provides)
