Hi,
If I understand right:
You want to run a zynq qemu on a centos host?

It is highly probable that the --usbdevice command try to create a
usb-ehci device and it doesn't find any PCI bus on the machine you
choose.

Then here I don't get it. Why are you using qemu-system-x86_64?
It will be approximately the same for qemu-system-arm though.
Only there is probably no PCI bus where to connect them.
Can you give the complete command you are using?
