Would something like =C2=A0 Using -nodefaults is required to have full control over =C2=A0 the virtual hardware: when it's specified, QEMU will =C2=A0 only automatically add a small selection of core PCI =C2=A0 devices, and leave the user in charge of adding more as =C2=A0 they see fit. More specifically, the PCI devices that =C2=A0 will always be present are: =C2=A0=C2=A0=C2=A0=C2=A000:00.0 Host bridge =C2=A0 This configuration file adds a number of other... work for you? Please keep in mind that I want to be able to use the very same paragraph both for q35 and mach-virt. --=C2=A0 Andrea Bolognani / Red Hat / Virtualization
