I have few VMs in Redhat Virtualisation environment RHeV ( using Rhevm4.1 ) managed

Now I am in the process of migrating those VMs to my cloud setup with OpenStack ussuri
version with KVM hypervisor and Glance storage.
The third party is making down each VM and giving the each VM image with their attached
volume disks along with it.
There are three folders which contain images for each VM .
These folders contain the base OS image, and attached LVM disk images ( from time to time
they added hard disks and used LVM for storing data ) where data is stored.
Is there a way to get all these images to be exported as Single image file Instead of
multiple image files from Rhevm it self. Is this possible ?
If possible how to combine e all these disk images to a single image and that image can
upload to our cloud glance storage as a single image ?
It is not clear what is the vm you are trying to export. If you share
the libvirt xml
of this vm it will be more clear. You can use "sudo virsh -r dumpxml vm-name".
RHV supports download of disks to one image per disk, which you can move
to another system.
We also have export to ova, which creates one tar file with all exported disks,
if this helps.
