Can't start any VM on new installation

Hi people!

I’m having trouble finishing up my first OpenNebula installation.
I have the sunstone configured and working in a VPS and I have one KVM node based on debian and I have a NAS storage that’s exporting through NFS to both the node and the Sunstone VPS.

I was able to download templates but when I try to create a VPS out of any template I get a FAILURE after a minute or so and I don’t know what could the problem be.

I suspect it’s either how I exported/mounted the NFS shares or some qemu issue.

What could be wrong? Please help.

Are you install NFS share and share /var/lib/one directory from frontent to node machine?
