I tried to test your patches, but I get in trouble quite early: I usually run qemu-system-aarch64 for pci for OSv with the following command line (using the patches from Alvise): ./qemu-system-aarch64 -nographic -machine type=virt -enable-kvm -kernel ./loader.img -cpu host -m 1024M -drive file=usr.img,if=none,id=hd0,media=disk -device virtio-blk-pci,id=blk0,bootindex=0,drive=hd0,scsi=off,vectors=0 -device virtio-rng-pci -netdev user,id=un0,net=xxx.xxx.xxx.xxx/xx,host=xxx.xxx.xxx.xxx -redir tcp:2222::22 -device virtio-net-pci,netdev=un0,vectors=0 and with this series I get: qemu-system-aarch64: Unknown device 'gpex-pcihost' for default sysbus Is there something I need to mention in the command line to enable the gpex-pcihost maybe?
