Marcus Sorensen commented on CLOUDSTACK-9813:
---------------------------------------------
It can be difficult for block-based primary storage to host the ISO, though a
primary-storage hosted ISO would eliminate live migration issues. I was
thinking the ISO would just be created on the fly in some host temp space
during the PrepareForMigrationCommand, along with the creation of relevant
network bridges and other setup on the destination. It also reduces the
exposure of potentially sensitive configuration information to the host on
which the VM resides rather than cluster-wide for primary or zone-wide for
secondary.

> Project: CloudStack
> Issue Type: New Feature
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: KVM, Network Controller, Secondary Storage, SystemVM,
> VMware
> Affects Versions: Future
> Reporter: Eric Waegeman
> Assignee: Kris Sterckx
>
> To avoid the use of an extra VM for the virtual router we implement
> configdrive for userdata, metadata & password.
> The configdrive ISO is created on the secondary store and the KVM & VMware
> plugins are adapted to accept the configdrive ISO as second cdrom.
> Is applicable for isolated, VPC and shared networks.
