I tried changing the 'emulator' to 'qemu-kvm' in libvirtdriver.cc file and reinstalling but I am still not able to shutdown the VM. I am able to do this if I install v1.2. I am using the following versions of hypervisor and libvirt

So, after the changes you are able to boot the VM but not to shutdown
it, right?. I am not sure why you can create but not shutdown. What
does the log files say?
I've updated the following issue to address also the "emulator" path:

Yes, we plan to make the hypervisor URI a configurable parameter in
the vmm_kvm.conf file. BTW, Does this solve the previous issue?

The permissions are as follows:

* Each VM and Network are owned by the user that creates them. (you
can now see ownership in the "list" commands)
* Each user can only managed her own VMs or Networks (i.e. shutdown
migrate delete...)
* Oneadmin can do anything

This is enforced by the OpenNebula core.

It is not really needed, it depends on the type of deployment you want
to make. If the users are *external* (e.g. will access to your
infrastructure through a cloud interface) you do not have to make a
system account for each user, just an OpenNebula one. However if those
users are the team of sysadmins managing the virtual infrastructure
for a site each one will probably have their own system and OpenNebula
accounts.

Thanks for the feedback!

Cheers!
