Subject [jira] [Created] (CLOUDSTACK-4606) HA does not kick on Routing VM hanging on kernel panic.
Date Wed, 04 Sep 2013 17:54:52 GMT
Roeland Kuipers created CLOUDSTACK-4606:
-------------------------------------------

             Summary: HA does not kick on Routing VM hanging on kernel panic.
                 Key: CLOUDSTACK-4606
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4606
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Virtual Router
    Affects Versions: 4.1.1
            Reporter: Roeland Kuipers


If a routing VM hangs on kernel panic. It will never be recovered by the HA process of Cloudstack.
In this case the Virtual Router cannot be accessed anymore over link-local and/or management
address and cannot be managed anymore.

We think HA should reboot a router when this occurs.

Errors observed while hanging:
