Thank you all, I was able to make it running (using some qemu-dm example 
in the example) at least for my testing of HVM guest read-only image 
handling fix (I didn't try it for PV guests yet) and I have to confirm 
that my patch to fix read-only image file handling (sent to the list as 
the first e-mail in this thread) is working fine with both 
xen-3.4-testing and xen-4.1-unstable. The fix is for xen-iommu located 
in iommu-dir (downloaded from git). Is this the right list to post this 
patch to? It can't be going to qemu-devel list since this is really 
closely connected to xenstore which is not a part of qemu at all so this 
is for the xenstore layer of qemu-dm mainly.
Thanks,
Michal
