Reverting OpenStack snapshots breaks installation
Hi folks. Im learing the openstack ropes currently. Im using VMware Workstation 10. I have successfully deployed Openstack and configured it for external networking. All good. I have created snaphots along the way in the hope I can simply revert to fully working state as I go along and break stuff.
Particularity I have been snap-shotting as I try to configure my installation to deploy docker containers. I had a working docker, but when I tried to push a container to glance something didn't work, when I went back to last snapshot I found I was unable to get back into horizon, after a lot of googling I got back in by
service openstack-ceilometer-api start but was greeted by a load of errors. I rebooted and now I cant spin up any test vm's I had stored. Compute seemed to be reporting itself down.
I will start from scratch again, but is there a safe way to take and revert to snapshots with out breaking my whole installation, as a packstack install takes me about 90 minutes to run each time to get started again
