First of all I want to say, that aggregate function isn't working at all, but it is solved by this post: https://ask.openstack.org/en/question/8392/aggregate-hosts/ After fixing sources aggregate is working now, I can add master and second host to pool (second host's node-compute successfully reboots and host adds to pool). But after adding second host I got problem with second hosts nova-compute, it won't start: 2013-12-12 09:52:08.114 13238 INFO nova.openstack.common.periodic_task [-] Skipping periodic task _periodic_update_dns because its interval is negative 2013-12-12 09:52:08.166 13238 INFO nova.virt.driver [-] Loading compute driver 'xenapi.XenAPIDriver' 2013-12-12 09:52:08.535 13238 CRITICAL nova [-] 'XenAPISession' object has no attribute '_virtapi' 2013-12-12 09:52:08.535 13238 TRACE nova Traceback (most recent call last): 2013-12-12 09:52:08.535 13238 TRACE nova File "/usr/bin/nova-compute", line 10, in <module> 2013-12-12 09:52:08.535 13238 TRACE nova sys.exit(main()) 2013-12-12 09:52:08.535 13238 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/cmd/compute.py", line 68, in main 2013-12-12 09:52:08.535 13238 TRACE nova db_allowed=False) 2013-12-12 09:52:08.535 13238 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/service.py", line 257, in create 2013-12-12 09:52:08.535 13238 TRACE nova db_allowed=db_allowed) 2013-12-12 09:52:08.535 13238 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/service.py", line 139, in __init__ 2013-12-12 09:52:08.535 13238 TRACE nova self.manager = manager_class(host=self.host, *args, **kwargs) 2013-12-12 09:52:08.535 13238 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 450, in __init__ 2013-12-12 09:52:08.535 13238 TRACE nova self.driver = driver.load_compute_driver(self.virtapi, compute_driver) 2013-12-12 09:52:08.535 13238 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/virt/driver.py", line 1108, in load_compute_driver 2013-12-12 09:52:08.535 13238 TRACE nova virtapi) 2013-12-12 09:52:08.535 13238 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/openstack/common/importutils.py", line 52, in import_object_ns 2013-12-12 09:52:08.535 13238 TRACE nova return import_class(import_value)(*args, **kwargs) 2013-12-12 09:52:08.535 13238 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/virt/xenapi/driver.py", line 142, in __init__ 2013-12-12 09:52:08.535 13238 TRACE nova self._session = XenAPISession(url, username, password, self.virtapi) 2013-12-12 09:52:08.535 13238 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/virt/xenapi/driver.py", line 666, in __init__ 2013-12-12 09:52:08.535 13238 TRACE nova self.host_uuid = self._get_host_uuid() 2013-12-12 09:52:08.535 13238 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/virt/xenapi/driver.py", line 698, in _get_host_uuid 2013-12-12 09:52:08.535 13238 TRACE nova aggr = self._virtapi.aggregate_get_by_host( 2013-12-12 09:52:08.535 13238 TRACE nova AttributeError: 'XenAPISession' object has no attribute '_virtapi' 2013-12-12 09:52:08.535 13238 TRACE nova I discover, that I can't set up nova-compute on "second host" in XenServer pool which is created by XenServer (without OpenStack aggregate), error is same.
