Note I found https://lists.launchpad.net/openstack/msg20738.html which seems to be not resolved.

Comment 4 Jaroslav Henner 2013-02-13 11:57:55 UTC

restarting the openstack-nova-scheduler seems to fix this.

Comment 5 Jaroslav Henner 2013-02-22 09:34:33 UTC

This may be a regression. I need to check that.

Comment 11 Jaroslav Henner 2013-03-21 21:06:58 UTC

I am not sure what have changed in my environment, I cannot reproduce with pre openstack-nova-2012.2.3-5.el6ost package, nor with newer one. So I guess VERIFIED
