In trying to install RHEL 7 from an ISO (instead of deploying from an existing KVM image) in Mirantis Open Stack, I run into Anaconda not being able to find the attached disk - and so installation cannot proceed.
There is a 160GB virtio disk (/dev/vda) attached to this image:
But Anaconda cannot see it:
The virtio drivers should be standard (as of RHEL 6.4) in the ISO - especially since Red Hat also distributes a KVM image of 7.2 that is "ready to deploy" with Open Stack with the same release date as the ISO media.
Why would the installer not be able to see the attached volume during install? Do I need additional drivers, etc to get it to load?
