KVM libvirt virt-manager failing to request root password

Hello,

I'm having trouble creating new VM's on Mandriva One 2009.1.

The problem seems to be that the Virtual Machine Manager does not 
request the root password and as a result I am unable to create new VMs.

I've attached a copy of the relevant virt-manager log file with my 
comments added.

Can you advise me how to proceed?

Many thanks,
