Issues with Xen 4.4.2?

anyone having issues with this specific XEN version?

root@stortest1:~# dpkg -l | grep xen
ii libxen-4.4 4.4.2-0ubuntu0.14.04.5 amd64 Public libs for Xen
ii libxenstore3.0 4.4.2-0ubuntu0.14.04.5 amd64 Xenstore communications library for Xen

Or let me put it this way: Anyone running this specific XEN version without having the issues described here:

In short, it’s this issue:

Tue May 31 14:52:34 2016 [Z0][VMM][I]: libxl: error:
libxl_dm.c:717:libxl__build_device_model_args_new: qemu-xen doesn’t
support read-only disk drivers

Sorry for crossposting and thanks for any hints!
all the best
