Virt-who is rebuilded with the new API: https://brewweb.devel.redhat.com//taskinfo?taskID=3780745
virt-who has been using the new REST APIs as of virt-who-0.3-3.el5. A quick check here is a output snippet: EVENT: Domain rhel6.2-64-hvm(-1) Stopped Shutdown Virtual machine found: Domain-0: 00000000-0000-0000-0000-000000000000 Virtual machine found: win: 05e1f656-3ff2-9cc5-0b3e-27c3de9ab811 Virtual machine found: rhel6.2-64-hvm: bb61ed8f-6d86-5658-25d0-d6a5ba75db82 Virtual machine found: rhel6.2-32-pv: 6edb91bc-ec4c-943d-2130-44da54044bb1 Virtual machine found: rhel6-64-pv: 68a0b766-0567-8e2e-646a-5631d03c45ff Sending update to updateConsumer: ['00000000-0000-0000-0000-000000000000', '05e1f656-3ff2-9cc5-0b3e-27c3de9ab811', '68a0b766-0567-8e2e-646a-5631d03c45ff', '6edb91bc-ec4c-943d-2130-44da54044bb1', 'bb61ed8f-6d86-5658-25d0-d6a5ba75db82'] which is mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=756380#c10 Although for Xen Domain-0 uuid shouldn't be sent as a guest uuid, new guest uuid upload method has already been used by virt-who. So, this bug has been verified and fixed. Other issues found later should be tracked in separate bugs.
