[Xen-users] [ARM][Xen-4.6] How to create stub domain?

[charles <charlescho64@xxxxxxxxx>]

Hello, 

I am trying to create stub domain on arm architecture(samsung exynos5250
SoC). Now xen 4.5 version is ported to target board with using linux kernel
3.18, and freely create domU by xl command.

but if stub domain is created by Dom0 or Domu kernel image under
configuration parameter(device_model_stubdomain_override = 1), stub_domain
is not created and the error message appear.
................................... error message
..........................................................................
Parsing config from dom0_stub.cfg
libxl: error: libxl_create.c:141:libxl__domain_build_info_setdefault:
qemu-xen access error: Bad address
........................................................................................................................................

Here, which is kernel image used for stub domain, dom0 or domu, or
others?(dom0 : backend driver support, domu : frontend driver support)

The configuration I used is like below.
........................................ stub domain configuration
....................................................
kernel = "/root/dom0_zimage"
name = "dom0_stub"
memory = 128
vcpu = 1
disk = ['phy:/dev/loop0, xvda, w']
extra = "earlyprintk=xenboot console=hvc0 rw rootwait root=/dev/xvda"
device_model_stubdomain_override = 1
.......................................................................................................................................

charles
