I was looking for a way to create a server and have it booted from a CBS volume that I prepared earlier from a snapshot.
The closest documentation I could find is "Boot a server from a Cloud Block Storage volume" (https://support.rackspace.com/how-to/boot-a-server-from-a-cloud-block-storage-volume/) , but it misses the option in the server creation screen in the control panel of selecting "Bootable Volume" in "Image Type" selection.
Thanks, it looks like that documentation is a little out of date. I will work on updating it.
Are you still having problems building a bootable volume server from image? Note that the source image must be 127GB or smaller, or you will not be able to use it to launch a bootable volume server.
If you have additional questions or concerns, please open a ticket for Rackspace Support.
