,host=04:00.0 -device pci-assign,host=03:00.0
The two PCI devices in question are behind a PCIe bridge which is connected to
the rootport. The crash seems to be happening when cleaning up the PCIe tree
of the passed-through PCI devices. I tried passing through the downstream
ports of the bridge as well, but that is not supported by qemu.
Am I doing something wrong/unexpected here ? Any help in understanding this
issue will help me fix the issue properly.
