Re: multiple users and xspice

If you are curious about how to get the Xspice seamles to work for a single user
Edit /etc/gdm/custom.conf (from the link to vnc setup)
[security]
AllowRemoteRoot=true
DisallowTCP=false

[xdmcp]
Enable=true
MaxSessions=30

Install the Xspice package 
on fedora its : xorg-x11-server-Xspice.x86_64

set a password in /etc/X11/spiceqxl.xorg.conf
Or disable it if you like living on the edge ;-P

mv /etc/X11/spiceqxl.xorg.conf /etc/X11/xorg.conf

restart X
connect with your spice client to the host on port 5900

Drawback: no more X on the console, only through spice.

Like I said in my first email, I already got Xspice to play along with xdmcp.And when connecting to the server using virt-viewer I get a nice desktop.

Now what I do not have is more than 1 concurrent user.
Also preventing the second user from hijacking the session from the first user is an issue.
Explaining that user one has session :1 and user two has session :2 is an administration nightmare.

It all has to work automagically.

Currently I only have vnc that does all this.
I implemented this solution : http://www.itzgeek.com/how-tos/linux/centos-how-tos/remote-login-with-gdm-and-vnc-on-centos-7-rhel-7-configure-vnc-on-xinetd-with-xdmcp-centos-7-rhel-7.html
But vnc is something that belongs in the previous millennium.

So I wonder if there is a way to do this using Xspice ?

      Hello all,

        I'm wondering if it is possible to get Xspice to work for
          multiple concurrent users.

        Currently I got it to work with xdmcp to start up a
          spice-desktop session.
        However when the second user logs in the session will be
          taken over by that user.

        Is it possible to get this to work with Xspice ? (or
          similar solution)
        Bonus points if it works with sssd.

    Hey Rob,

    The idea with XSpice is to run one Xorg process per user session. 
    And that does work; I use it extensively.  There is not (yet) a
    seamless way to do this on Fedora.  I was just playing with this on
    Fedora 21, and it's still very fiddly, particularly with gdm. I
    found that if I modified /etc/gdm/custom.conf to enable xdmcp and
    set the ping interval to 0, then a 

      XSpice -query localhost  <other parameters as needed>

    seemed to work, although I had to set aside my play while it was
    still fairly fiddly.  I was hoping to get more time to play to write
    a little bit of apache fu to spin up a user session on demand, but I
    haven't gotten to it yet :-/.

    Cheers,

    Jeremy
