Initially I am going to see how it improves the situation upgrading to KVM-84 of backports of Hardy Heron, since at the moment last kernel available for Hardy is the one I has commented. I would like to know if the newest versions of KVM published in the official site of the project solve a bug recently reported in Ubuntu Launchpad [1]. Also I was observing errors of type 'to swapper Not tainted' or 'java Not tainted' in the VM (aps2, with a high rate of I/O) and that I've commented in a previous message sent to the list [2]. I would want to know if you could indicate to me if this can be due to KVM bug that would be solved in a later version. Thanks for so quick reply.
