Re: [openstack-dev] [Nova] Boot from ISO feature status
Hi Daniel, For now (IceHouse), it's not possible to boot from iso and attach volume after boot. Libvirt present ISO disk via an IDE controller (/dev/hda) and new volume try to be added as IDE too (/dev/hdb). Do you mean that with the new block device mapping code, we will be able to boot from ISO (/dev/hda) and add a new SATA volume (/dev/sda)? -- Jean-Daniel On Mon, Jul 28, 2014 at 09:30:24AM -0700, Vishvananda Ishaya wrote: I think we should discuss adding/changing this functionality.

Re: [openstack-dev] [Nova] Boot from ISO feature status
Hi Daniel, Thanks for the feedback. I have two questions: 1. Is it available in Havana? 2. Is it possible to to say that the glance image should be fetched to a CDROM device (and disk file named 'iso'), and the root disk should be created blank according to the flavor settings (disk file named 'disk') Best regards, Max Lobur, OpenStack Developer, Mirantis, Inc.

There is a blueprint for this - and it would also provide what Vish mentioned elsewhere on the thread (having a root drive that you can snapshot) [1]. Sadly - I never found the time to start this work, although there seems to be interested people from time to time - no one has picked it up either (hint, hint). If someone does - I'll be super happy to review it! N.

Re: [openstack-dev] [Nova] Boot from ISO feature status
Hi guys, In the Hyper-V driver camp we waited to add the boot from ISO feature because of this issue. Booting from ISO w/o local storage is almost useless for most scenarios. It'd be great if we could reach consensus on this and propose some consistent BPs for all supported drivers in early K-1.

Re: [openstack-dev] [Nova] Boot from ISO feature status
Vish, Exactly. Snapshots is the main reason why I started to modify Nova. There's a high probability that we will contribute our work to Nova nearest time.
