Good morning,

I wanted to know if there will be an installation process from scratch 
with a reboot for the hosts as there was in 3.0.

I have an issue that may also be related to authentication. I am unable 
to start my newly created VM. The engine seems to connect to libvirt in 
read-only mode, and boot of the virtual Machine fails. There is 
something quaint in virsh (Fedora 17 in the hosts):

when trying to connect without specifying the uri (qemu:///system) it 
gives segmentation fault. If it is given it asks for user and password.

Tried to disable sasl in libvirtd.conf and now I can connect with virsh 
to the default uri without providing a password, but booting of the vm 
keeps failing.

It is required to use sasl or to add a sasl user in the engine, in the 
hosts or in both?

And there is a log in /var/log/libvirt/qemu for the VM that says:
