CloudStack Console Proxy Certificate Expiring on 7 February 2012
The Citrix CloudStack engineering team is addressing issues with all deployed CloudStack instances. The SSL certificate that is used by the console proxy VM, which provides guest console viewing access to tenants) will expire on 05:15:23 GMT on 7 February 2012. When the certificate expires, users will get warnings/errors from their browsers when they attempt to view the console of their guest VMs. Exact behavior is dependent on browser vendor, browser version, and user settings.
For public clouds, or clouds that have frequency console viewing, it is recommended to apply the patch described in this knowledge base article (http://docs.cloud.com/Knowledge_Base/Updating_the_SSL_certificate_for_realhostip_domain). This patch should be applied before 05:15 GMT on 7 February.
For private clouds, or clouds that have a low use of the Console viewing feature, you can choose to not apply this fix and wait for 2.2.14 or 3.0.0. You will still be able to use the guest consoles, but depending on your browser you will get an alert once the certificate expires.
Instructions for using your own SSL certificate are located at the bottom of the above KB article.
