Thanks for your response. This is not overprovisioned system but you can have a bug somewhere that lead to use all memory and, of course, you have to correct it. But all other zones in the system will suffer from this situation and in consolidation context, it's annoying. As the zones are moving from one system to another, it's not so easy to use memory capping. This is why a reserved memory could be more intelligent and practical.

This is to prevent all memory being catched by other zones and eventually you can't do anything to free this memory. Due to the shortage of memory, you can't even log in to the machine. I'm aware of memory capping but this is a little bit different. Feel free to share your thoughts about this stuff.We currently don't have a way to reserve a set of memory for a zone, so the best you can do is always set the memory caps on each zone to ensure that there is still plenty of memory left for the global zone. Can you describe the environment you're in where this won't be sufficient? Are these actively hostile zones? Is this system overprovisioned so that there is just not enough memory?
