Is there a way to export the VM disk images from Xenserver? If so you should be able to spin them up on a KVM host and then use v2v to import these into oVirt.

Probably the main problem is with PV VMs and so the problem could be re-read in how convert them to HVM and then apply P2V iso.

This link below is the reverse (HVM-2-PV) but the method idea in your case could fit what described:

https://netnow.co/xen-virtual-machine-conversion-from-hvm-to-pv/

Inside the article there is in fact a link to do the reverse:

http://djlab.com/2010/10/convert-xenserver-hvm-to-pv-paravirtual/

that you can use, if still feasible (XenServer 4.x described vs your XenServer 6.x) to migrate to HVM layout and boot method.

Then you can migrate the obtained VM with P2V iso provided by RHEV/oVirt

It seems it worked for someone (late 2013), as described in latest post here:
