Subject [jira] [Commented] (CLOUDSTACK-429) Agent rebalancing is broken
Date Wed, 31 Oct 2012 12:19:12 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-429?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13487701#comment-13487701

Roland Kool commented on CLOUDSTACK-429:
----------------------------------------

This is broken in 3.0.2 and a bug in bugs.cloudstack.org was filed (http://bugs.cloudstack.org/browse/CS-15460)
but no fix has been created. I assume this is then still broken in CloudStack 4.x
