I suggest add some tracing to function dom0_init() in xenstored and see
where that function is failing. The two most obvious places were the opening of those two files in /proc. If they exist then I'm not sure what else could
be going wrong.

Oh, you should be able to cat /proc/xen/ksd_port and get an integer value.
/proc/xen/ksd_kva by contrast gets mmap()ed by xenstored.

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
