cpu overcommit?

Ok, so I'm running into these errors when running my vm's. I assume it's my cpu getting over taxed, but honestly I'm a Linux N00B so I have no idea how to read the syslog syntax .... it's all french to me 

I've noticed that my VM's will stall, the web GUI takes forever to load and then when I look at my syslog these errors are popping up. This only happens when I have my Windows vm running. (however I have to admit that I have 2 arch vm's and an ubuntu VM running as well 24/7... So this is probably me being an idiot and running too many vm's but either way... better to be safe than sorry

so.. anyone mind looking through this and telling me what it means?
