kernel BUG at "/build/linux-lts-xenial-UweaL0/linux-lts-xenial-4.4.0/arch/x86/kvm/mmu.c:1366!"

My OpenStack system have just an accident of crash one compute host.

Compute host information:
$ lsb_release -rd
Description: Ubuntu 14.04.5 LTS
Release: 14.04

$ uname -a
Linux compute2.hn.vnpt 4.4.0-62-generic #83~14.04.1-Ubuntu SMP Wed Jan 18 18:10:30 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

When I checked syslog in this compute, I found this log as issue happened. This log begins with:
"kernel BUG at /build/linux-lts-xenial-UweaL0/linux-lts-xenial-4.4.0/arch/x86/kvm/mmu.c:1366!
Oct 15 14:10:13 compute2 kernel: [12845630.282893] invalid opcode: 0000 [#1] SMP "

And after that, CPUs stuck in turn.

Could it be a bug in kernel of Ubuntu 14.04.5??
