> My concerns are whether this will work in the case you already used the > leases helper as the patch is adding a few fields to the stored format. In this patch, I am only adding server-duid as an extra JSON object. I am not adding more fields to an existing JSON object. The old leases file will certainly work, even if server-duid is not present. Server-DUID will get added in any event which will get triggered from the ipv6 interface. But all of this will happen assuming dnsmasq and libvirt have been restarted. -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
