I won't hold up the series because of it - in fact I intend to push it as soon as you have given me feedback for the few trivial questions I've raised during review - but I think this decision should be reverted. I've noticed that the generated command line contains -usb, which is the legacy syntax for USB support: these days guests are supposed to use -device instead, hopefully with a virt-friendly USB controller such as qemu-xhci. All those controllers are PCI, though, so they won't be usable on RISC-V until the architecture grows PCI support in QEMU... Still, we have spent a long time moving away from -usb and I don't think we should be introducing any more uses of it, so we should write a follow-up patch that gets rid of that in addition to getting patch 5/11 from v2 in. It's not like RISC-V guests would have much use for a USB controller anyway... $ qemu-system-riscv64 -device help 2>&1 | grep -i usb name "usb-redir", bus usb-bus $ -- Andrea Bolognani / Red Hat / Virtualization -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
