Can you ssh to the hypervisor and run virsh list to make sure your instances are in fact down?

Hi folks, Because of power outage, Most of our compute nodes unexpectedly shut down and now I can not start our instances. Error message is "Failed to get "write" lock another process using the image?". Instances Power status is No State. Full error log is http://paste.openstack.org/show/754107/. My environment is OpenStack Pike on Ubuntu 16.04 LTS servers and Instances are on a nfs shared storage. Nova version is 16.1.6.dev2. qemu version is 2.10.1. libvirt version is 3.6.0. I saw a commit [1], but it doesn't solve this problem. There are important instances on my environment. How can I rescue my instances? What would you suggest ?
Thanks, Gökhan
