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.
