I wasn't aware of problems in VNC.
So is there a work around ? How can I work remotely, if VM networking is local (ie- NAT)
?
The VNC issue is only if you are connecting to your remote machine using
VNC, not if the VMs are using VNC. The alternatives are to run
virt-manager as root on the remote machine, use ssh -X instead of VNC,
or possibly alter PolicyKit rules to auto allow connecting for that user
(though I haven't tried it, and it may still fail).
