Thread-topic: PCI passthrough not working on ARM64 QEMU

Hi,

I'm running Xen on ARM64 QEMU and trying to run PCI passthrough. But I'm getting following error:

root@qemuarm64:~# cat /etc/xen/domU.cfg

kernel = "/boot/Image"

ramdisk = "/boot/rootfs.gz"

memory = 3000

vcpu = 1

extra = "rdinit=/sbin/init root=/dev/ram0"

name = "guest"

pci = ['00:01.0']

root@qemuarm64:~# xl create -c /etc/xen/domU.cfg

Parsing config from /etc/xen/domU.cfg

libxl: error: libxl_create.c:1164:libxl__domain_config_setdefault: passthrough not supported on this platform

Moreover, I see following message:

(XEN) I/O virtualisation disabled

Should I/O virtulization be enabled to make PCI passthrough work on ARM64 QEMU and do we have steps documented somewhere regarding this?

Regards,

Fahad
