Hi,

-machine pc,accel=xen is to be used by libxl (used by xl or libvirt).
libxl takes care of creating a guest and launch QEMU when needed.

There are some QEMU options to start a xen guest with standalone qemu,
but I don't know if they works. Look for -xen-create. But I don't think
that is what you would need.

What is your xen config file for OI ?

Also, how do you start OI with KVM/tcg? (qemu command line)

q35 won't work with Xen.
