i am not familar with the mips emulation but just in case its useful I suspect this is related to the machine type https://www.qemu.org/docs/master/system/target-mips.html the default one i don't think support PCI devices so malta? might be required.
the Loongson-3 virtual platform might also be work trying https://www.phoronix.com/scan.php?page=news_item&px=Loongson3-Linux-5.8-KVM-Virt it sound like it a realitive recent platform. https://listman.redhat.com/archives/libvir-list/2016-May/msg00197.html which you reference before was related to the malta machine type. so it seam to confirm it has a root PCIe controller so that is probably the best place to start. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1561497 Title: XML error: No PCI buses available when defining MIPS VM To manage notifications about this bug go to: https://bugs.launchpad.net/libvirt/+bug/1561497/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
