I heard there was some discussion during KVM forum. Fwiwi, this is also an idea I proposed last year (and quickly discussed during my talk about multi-process qemu). I also experimented with the idea, and wrote a vfio-user backend, with a PCI serial device running in a seperate process: the qemu tree: https://github.com/elmarco/qemu/tree/wip/vfio-user (dirty tree) and the serial device: https://github.com/elmarco/qemu/blob/wip/vfio-user/contrib/libvfio-user/vfio-user-serial.c > > cheers, > Gerd >
