This may be costly, but we can have have a libvirt migration hook run on the source AND the destination hosts. The source hook would convert everything to /rhev/data-center/ to fit old hosts; new hosts would re-convert it to /var/run/ovirt-hostd. _______________________________________________ Devel mailing list Devel@ovirt.org http://lists.ovirt.org/mailman/listinfo/devel
