In some cases host asks us to overballoon and this triggers OOM killer which eventually kills everyone. The easiest way to get into such situation is to avoid onlining memory-hotplugged blocks. Address the issue twice: - Report offline pages as used to the host so it won't ask us to overballoon; - Avoid ballooning below the 'floor'.
