In turn, this is quite often a bug, because forward migrations (e.g.
from 2.3.0 to 2.4.0) are always supported, for obvious upgrade needs.
So, which version of libvirt and qemu do you have on the sides of

This is the default Engine sends.

Can you share what is running on your hypervisors? versions of libvirt and
qemu.
Moreover, qemu and libvirt logs would help.
Thanks,

192.168.1.53 is the hypervisor host I used
Now the point is maybe I did some mistakes or overlooked some configuration
steps
(maybe blindly hit return instead of changing a default), but I suggest to
improve
the docs/wiki to document how to fix common gotchas and/or to reconfigure
thing
/show_bug.cgi?id=1114978
besides that the feature seems to work nicely

erienced the same problem reported here
https://bugzilla.redhat.com/show_bug.cgi?id=1067064
A fix was already been committed.
About kvm and libvirt, you only need them on the nodes running hypervisors;
engine itself does not depend on them.

se newer versions of QEMU have improvements
on this
field: QEMU recently gained native block devices[1], which, among other things,
will make
it more robust in presence of I/O errors, and should improve the error
reporting as well.
RHEL7 should have a version of QEMU with native ISCSI; hopefully NFS will
follow soon
enough.
HTH,

[1] for example, ISCSI, recently merged:
