Thanks for responding. So, this feature isn't available in 4.4.10 as we are intending to move to that version? Storage used for that VM is NFS.

Hello,

I’ve researched a bit on how to convert a disk image from pre-allocated to thin in Ovirt 4.1, but nothing worked. Is there a way to achieve this please?

Yes! 1. Install ovirt 4.5.0 2. Use the new convert disk feature With oVirt 4.1 you can do this manually. What kind storage are you using? (NFS, iSCSI?) Nir
