RFC: Allow use of local ISO image to install guest on remote connection

Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Using virt-manager to connect host B on host A (Remote tunnel over SSH
2. Create a new guest on host B with host A's virt-manager
3. # ll /var/lib/libvirt/boot/boot.iso

Error setting install media location.
Checking installer location failed: Could not find media '/var/lib/libvirt/boot/boot.iso'.
It can be booted up.

If you are trying to use an ISO on Host A to install a guest on Host B, that isn't possible. ISO media must be available on the remote host.
If the ISO is on Host B, it needs to be in a libvirt storage pool. Try moving the ISO to /var/lib/libvirt/images or make /var/lib/libvirt/boot a storage pool using virt-manager.
As a thought, would it be practical to make this work?
Asking because solutions exist whereby a person using a web browser can manage remote servers, and then boot those servers using a virtual CD image (iso) on the local users pc.
ie Remote management of IBM blade servers using Firefox. A java applet in
Firefox communicates with the blade enclosure "controller" software, and
pipes (?) the iso file to the remote server. The remote server sees it
as locally attached CD/DVD.
I've personally used this approach before, and it generally works pretty
well with decent LAN connectivity to the servers. (ie when located at
the same physical site)
Having the same kind of thing work through virt-manager would be useful.
Yeah I guess that's a valid RFC, no idea how we would solve it though.
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.
** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
This is unlikely for 6.1, moving to 6.2
We could use new libvirt volume upload API for this.
I think libvirt would support this in a way, but exposing this in the UI in a reasonably informative way is still up in the air. Deferring to 6.3 for now.
Not urgent, and given reduced capacity for virt-manager/virtinst, just moving
this to the upstream tracker.
While this is a cool idea, I don't think it's ever going to be implemented. Really the only way I can imagine it would work is to upload the ISO to the remote host, and if we are dealing with say a DVD that means a lot of data. I'm fine with just saying 'upload the media on your own, or use a URL install' unless users start suddenly clamoring for it.
