+description = """I cross-compiled a riscv64 QEMU flavor based on the most updated code, then make check. Some qemu-iotests failed, 040 041 127 256 267. I mainly focused on test 040 and tried to find out what happened."""
+reproduce = """1. change directory to QEMU source tree root
+2. ./configure --prefix=~/temp --target-list=riscv64-softmmu
+3. make
+4. cd build/tests/qemu-iotests/
+5. ./check -qcow2 040
+
+Then a lot of error messages(please see attachment). The following log might hint the root cause I thought:
+```

++qemu-system-riscv64: -device virtio-scsi: No 'PCI' bus found for device 'virtio-scsi-pci'
+```
+The command had no '-machine' argument. For riscv64 target, 'spike' will be the default machine. Maybe 'spike' have no PCI bus? Then I tried to change it to 'virt' machine but failed, nothing new happen.
+```
+QEMU_DEFAULT_MACHINE=virt ./check -qcow2 040
+```
+```
+QEMU_OPTIONS="-machine virt" ./check -qcow2 040
+```
+Last, I modified [testenv.py](https://gitlab.com/qemu-project/qemu/-/blob/master/tests/qemu-iotests/testenv.py#L239) and added one line in machine-map, all tests passed!
+```
+('riscv64', 'virt'),
+```
+
+Is there any way to easy the issue or do I miss something? Thank you!"""
