There is no equivalent to the x86 "hvm" type guest, i.e. one which looks to the guest like a real system, in the ARM version of Xen. On x86 stub-qemu is primarily about providing these emulated system devices in a sandboxed environment. There are no emulated devices on ARM hence no need for qemu for this purpose, hence no stubdomains. qemu has a "second hat" when in a Xen system, which is that it can provide certain PV backends, we do use it for this purpose on ARM. > To run the Linux on Dom0 and DomU.

Yes, qemu can be used to provide PV backends for: disk (using qdisk), framebuffer, kbd and mouse.
