VMM 2008 R2: Host Needs Attention After KB978560

I saw this one last night for myself and I’ve just seen a week-old post by Mike Briggs on the subject.  When you deploy KB978560 to your VMM 2008 R2 server, it will require an update to the agents.  You’ll see a yellow exclamation mark icon appear on your hosts.  When you check their status you’ll see that you must take manual action to resolve the issue.  Simply right-click on the managed hosts, update the agent, and provide any required credentials.  It takes a minute or two, then you’ll get your “issue” resolved. 

Be sure to put the hosts in maintenance mode in OpsMgr if you’re using it.  Otherwise you’ll get a bunch of alerts for every host you upgrade.
