@Amir_AramaI was able to import the R80.40 OpenStack / Nutanix AHV / KVM qcow2 image from sk158292 to our Nutanix image service, then clone the disk as a SCSI disk during creation of the Management guest VM. This created a system that booted and was ready to run the first-time wizard. From there I was able to install it as a secondary management server, and sync to it from our primary. At this point I am currently actively testing this build so I don't have further results to share (positive or negative).
Note this does only give you the single 100GB disk - as I indicated in my previous post I was able to add additional storage capacity by following the general process outlined in sk94671: creating a new disk, adding it to the VM definition, then going through the LVM process within Gaia to add the new disks' capacity at the OS level.
