We're running Ubuntu 14.04 on an EC2 virtual machine. I've been seeing a lot of these errors in our kernel log:

[  704.032085] xen:balloon: reserve_additional_memory: add_memory() failed: -17
[  736.096102] xen:balloon: reserve_additional_memory: add_memory() failed: -17
[  768.160075] xen:balloon: reserve_additional_memory: add_memory() failed: -17
[  800.224082] xen:balloon: reserve_additional_memory: add_memory() failed: -17
[  832.288094] xen:balloon: reserve_additional_memory: add_memory() failed: -17

We obviously aren't running Xen within our virtual machine, so these must indicate something to do with the host's allocation of memory. I don't believe it's causing any immediate problems for us, but is it something we should be concerned about?

This is a known bug in few HVM EC2 servers.

It is unclear if the issue is in the kernel or Amazon's configuration for EC2.

You'll have to add/use the following PPA to fix this:

Using this PPA resolved the issue for most of the users.
