libvirt users - Feb 2022 - QEMU args generation order with libvirt

Hello,

We are trying to bring up the Android VM with Libvirt, as part of this exercise
it is advised to keep Replay Protected Memory Block (RPMB) device as the first
virtio device in the QEMU arg list, as the secure storage daemon in Andriod side
communicates with dev/vport0p1 for RPMB usage.

Is there any way we can make a qemu commands generation in particular order with
Libvirt XML ?

Thanks,
Shivakumar M

Unfortunately no. While libvirt allows passing arbitrary cmd line
arguments (https://libvirt.org/kbase/qemu-passthrough-security.html)
these are appended only after libvirt generated part.
