Re: [Openstack] Snapshotting ephemeral disks?
This is not possible. Sounds like you really want a fix for this bug: https://bugs.launchpad.net/nova/+bug/914484 The fix was reverted but hopefully it can be cleaned up and come back in. That looks like it would get us where we want to be. My main goal is to have a relatively easy process for someone without administrative access to the host to... - Uploading an ISO image. - Boot an instance from that image. - Install an OS onto something. - Transform something from the previous step into a deployable image. Allowing images booted from an ISO to have an attached, snapshottable root drive would certainly work. -- Lars Kellogg-Stedman l...@seas.harvard.edu | Senior Technologist| http://ac.seas.harvard.edu/ Academic Computing | http://code.seas.harvard.edu/ Harvard School of Engineering and Applied Sciences | ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
