Migrating VMWARE Image (OVA) to RHEV 3.5 as a VM

I would like to share with you this secret way of migrating any VM from any hypervisor to RHEV. Red Hat has not mentioned this anywhere on the internet so I would recommend you to do this only on test environments:

1) Extract the OVA image using: tar xvf CFusion-server.ova

2) Convert the extracted VMDK disk file to raw lvm image using: qemu-img convert -f vmdk CFusion-server-disk1.vmdk -O raw CFusion-server-disk1.img

3) SCP the image (.img file) to you NFS exports server (also, Check the VM size)

4) In RHEVM, create a VM with same sized disk (preallocated)

5) Export that VM (to export NFS) and delete the newly created VM

6) Check the export VM image in images folder on NFS export location

7) Put export in maintenance mode and on nfs server, use dd command to write the main exported disk file under images folder

8) Now, activate the export again

9) Create a VM with THIN disk from exported image

You can see that VM is ready for its first run!
