Hi, Currently, expansion ROM of assigned devices will be loaded into guest and execute. You can just comment out one line code (assigned_dev_load_option_rom() in qemu/hw/pc.c) to let qemu don't load expansion ROM, and then this issue should be gone. I met this issue before, but there was no problem when I assigned the same device to a guest in Xen which also load and execute expansion ROM. I guess it's caused by the difference between Xen guest bios and kvm guest bios.
