At the last couple volumes meetings, there was some discussion of the desired behaviors of nova's boot from volume functionality. There were a few use cases discussed, but there are probably plenty we didn't think of, so it would be useful to get input from a larger audience.
What use cases for boot from volume are people interested in, and which should nova support? Here are a few use cases: 1) I use an existing instance to manually create a bootable volume containing an OS there is no image for (and I cannot create an image). I boot the new OS from the volume I created. 2) I create a bunch of new instances that have no ephemeral disks, but are all based on the same image. The data from the image is copied to a new volume for each new instance. 3) I have an instance that has no ephemeral disks, and stores everything in a volume. I take periodic snapshots of the volume. Later, my original instance becomes corrupted, and I want to restore from the last known good snapshot I took. I boot a new instance from a new volume created by cloning from the last good snapshot. _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : email@example.com Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
