Hello Benny, Not sure if I can email you directly, but you helped me once. I have some VM's which are labeled with specific affinity. Via API I would like to get a VM affinity label, in order to later get the hosts defined under that affinity. I tried many ways as: vm = vms_service.list(search='<vm_name>')[0] print(vm.affinity_labels) or: for affinity_label in affinity_labels: print("%s:" % affinity_label.name) for vm_link in connection.follow_link(affinity_label.vms): vm = connection.follow_link(vm_link) print(" - %s" % vm.name) Getting an href error: Error: The URL '/ovirt-engine/api/affinitylabels/0d68b36e-455a-4054-9958-0503d54a18db/vms' isn't compatible with the base URL of the connection Href's are looking fine, as: In [77]: for x in affinity_labels_service.list(): ...: print(x.href) /ovirt-engine/api/affinitylabels/0d68b36e-455a-4054-9958-0503d54a18db /ovirt-engine/api/affinitylabels/862df742-fdc4-4eb0-933c-027729e2187d /ovirt-engine/api/affinitylabels/686d96a6-0c9c-4fb7-b453-a79cbd48790b /ovirt-engine/api/affinitylabels/6d42df24-c4b1-45e7-8029-0ce26b8ed73d Or this: 1 for affinity_label in affinity_labels: ----> 2 for h in connection.follow_link(affinity_label.hosts): 3 print(h) 4 5 /usr/local/lib64/python3.6/site-packages/ovirtsdk4/__init__.py in follow_link(self, obj) 782 raise Error( 783 "The URL '%s' isn't compatible with the base URL of the " --> 784 "connection" % href 785 ) 786 Error: The URL '/ovirt-engine/api/affinitylabels/0d68b36e-455a-4054-9958-0503d54a18db/hosts' isn't compatible with the base URL of the connection Not clear what is the right way to get a VM affinity hosts list. Thanks, Lavi
