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)
- webaholic 10y agoThis allows you to create one host thread per guest vcpu, so yes, you can run a smp guest on aws. But, it will be pretty slow compared to KVM, since the execution of the threads is limited by the host cpu resources and the fact that you are using translation and full system emulation.
- compsciphd 10y agoso I guess that means QEMU always does full translation instead of just translating the privileged ops? (ala what vmware's innovation back in the day was)
- dfox 10y agoIt means that you can run SMP guest on SMP system and use more than one host core for that. You could run SMP guests before, but they were limited to only one host thread.
