troubles starting virt-manager as a user

[ToddAndMargo]

Hi All,

Normally when I start virt-mamager, I get a root password
prompt from xfce-polkit.  I accidentally pressed
"Deny".  Now it won't start from a user anymore

But I can start it from a shell as user root.

But I can not use "su" or "beesu" to start it
from a user's account:


$ su root -c virt-manager
Password:
$ No protocol specified
Unable to init server: Could not connect: Connection refused
No protocol specified
Unable to init server: Could not connect: Connection refused
No protocol specified
Unable to init server: Could not connect: Connection refused

(virt-manager:28209): Gtk-WARNING **: 12:39:57.414: cannot open display: 
:0.0


$ beesu virt-manager
$ No protocol specified
Unable to init server: Could not connect: Connection refused
No protocol specified
Unable to init server: Could not connect: Connection refused
No protocol specified
Unable to init server: Could not connect: Connection refused

(virt-manager:28244): Gtk-WARNING **: 12:40:09.291: cannot open display: 
:0.0


Any words of wisdom?

Many thanks,

I assume it saves that somewhere, but maybe only in memory.  Have you 
tried restarting the desktop or rebooting to clear it?

How are you doing that differently than the options you list below that 
aren't working?

The root user doesn't have permission to access your display.  You could 
use xhost to allow it if you want.

I can not log out at the moment.  Too many things going on.

Try "xhost +si:localuser:root".  You run that as your user.

That worked.  Thank you!

Don't forget to add the user to the libvirt group in /etc/group.  You won't
get a password prompt if you do that.
