Before this, I manage to run VM Debian then after installation complete , I shut it down and when run it back I unable to run it back as it mentioned the error "cannot run VM low disk space on target storage domain local_storage."

I do check my server df -h , yes I have too much space on the root partition where all the ovirt-engine setup was there, but we have more unused space at /home partition, then what I do after that we copy the images(iso file) for that particular vm into the /home partition then rename it according to path stated at the ISO_DOMAIN.

By doing all the process I can't manage to run the VM yet and get the error message stated that "VM Debian is down. Exit message: child quit during startup handshake: Input/output error."

Is there anyone can help us to solve this problems, or give us the solution that we can figure out on how can we run the VM. 

Thank you in advance.
