I have an Openstack Juno setup with one controller node and 3 compute nodes. I installed it using packstack on centOS 7. One of the compute node crashed twice. First crash was two days back and second one today. It automaticalley restarts after the crash. The crash log in /var/crash were different in both the instances.

Could you check /var/log/libvirt/qemu/instance-xxxxxxxxxx.log files on Compute Node for suspicious entries.
Specifically VMS having VCPUS => 2
