For the case of something like a live CD, it seems like you want to be able to specify a VM without a hard drive attached to it. This is especially painful as you have to go through and recreate the VM every time you want to restart the live CD -- after the first start, you're kicked over to boot from hard drive instead of from the CD.
Some first cut patches for LiveCD support here: http://www.redhat.com/archives/et-mgmt-tools/2007-May/thread.html#00010
change QA contact
Really two parts to this: 1) No way to boot from CD after initial install (GUI issue) 2) You want to not be required to choose a hard drive. I was told by #kvm that a hard drive isn't required by qemu. It *could* be set to /dev/null (if virt-manager didn't reject it).
Me too, i need to boot from CD after initial install with GUI. This is because screen just before the first start don't let to use several hard drives. I my case two solutions : - during initial vm creation screen, to be able to have several hard drives. - after vm is created, to be able to boot from CDROM.
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
The pending virt-manager release has a completely redesigned 'New VM' wizard. Details here: http://blog.wikichoon.com/2009/02/virt-manager-in-fedora-11-new-vm-wizard.html One of the new pieces is the option to skip specifying storage. If CD/ISO media is used for the install, and no storage is selected, livecd behavior is implied (always boot off CD). This definitely won't ever be backported to F9: these changes rock the boat a bit too much. Moving this bug to F10 (which is a likely eventual target).
I think it's too late to be backporting a major virt-manager version to F10, so this bug won't be fixed. Moving to F11 and closing as CURRENTRELEASE.
