Start VM in images directory after upgrade to proxmox 3.0-23

I have upgraded to proxmox 3.0-23 from 1.9 (using the Wiki steps, thank you for that)
The server works fine, no VM's

I want to save time performing VM's restore.
Since the /var/lib/vz/images still contains all my vm's
and /var/lib/viz/template/iso still contains all of the iso

Can I restore my VM's since they are under the images directory, without performing a restore from backup?
Is there a command that does this.

I can see all my vm from web interface under content, but no way to restore from there.

Please help
