Recover datastore without DB


I have all dirs (datastores, remotes, VMS), because the VMs were in a separated disk before the happy crash.

But I have lost the DB (was mysql on my server).

The question:
Is there any possibility of recovering the vms without the DB?
I mean, manual mapping or something?

Thanks in advance!

What kind of virtualization are you using? If you are using KVM you can use virsh [1] for managing guest domains.
