I just upgraded one of our heavy-kvm-usage host from 3.10 to 3.16, and it started showing these messages (hence I started searching and found this thread from 2013). Has it not been decided to downgrade this message to KERN_DEBUG for some reason? What does this message mean anyway? Why this very rare case (according to comments in arch/x86/kvm/mmu.c) happens on this machine?
