This article is just a collection of ideas and posts.

Recently I was doing some performance-tunning of QEMU/KVM with kinds of pure-software ways. However, it ended with the existence of QEMU/KVM’s process load.

I just remembered that I used to do some co-sim work with National Instruments LabView about ten years ago…(during college life…fk…I’m still young…)

Trial No.1

TBD: Start QEMU instance(s) with passthrough-ed PCI(PCI-SRIOV) devices like ethernet controller or NVMe controller designed in PCI FPGA to DECREASE the emulated works.

Trial No.2

TBD: Start QEMU instance with devices ported to passthrough-ed PCI FPGA as many as possible, i.e. usb controller, ethernet controller and etc..(Like a dock with kinds of devices…)

But I think it will be replaced by Trial No.1.

Trial No.3

TBD: Co-Sim.
