      So here's the issue, and the two choices for a solution, either make sure XO is being run under root, or add my user XOAdmin to the fuse group.

      xoadmin@xo-test-debian-3:/run/xo-server/mounts/remote-17/vm_delta_Critical VMs_b3d4662d-7358-0f49-e4c0-14bf3958488e/vdi_ee8f1bc2-fdd3-46b7-a44b-cf60a7b2f8b7$ sudo -s

      Which searching for the fuse group doesn't result in any visible output. So I have to either get XO to run under root (which systemctl should already be doing this...... ) or I need to add xoadmin to the fuse group.

      Any pointers?

      @danp was having similar issues, waiting to get some feed back from his investigation with @julian.

          Under /dev I do have fuse.

          So the system is there, yet there is no security group for fuse. . .

            How are you currently starting xo-server?

              AFAICS, my issues are unrelated.

                It must be starting under xoadmin (but it starts before login).

                  Systemctl is operating the server service.

                    @DustinB3403 Details please! 😉 I know you're on Debian 8. Is the process different than on Unbuntu where we used systemctl to create a service?

                    Edit: Thanks!

                      I'm stretching my memory here, now only god knows what I did to get this working.... 😄

                      FML.... the service has to be started with my user account, it's the only thing that makes any sense. So I'm curious if I can get the service to start with root instead...

                        Did you use the instructions on Mangolassi here to get everything installed and running? If so, it's running under systemd.

                              @DustinB3403 The 2nd line is just your current command. So it appears that node / xo-server are running as root.

                                Then the issues isn't a permission one, as @julian said in the OP..... which means it's something else to be able to mount the VHD..

                                  This is what I currently get from logging while trying to select a VHD to mount.

                                      I wonder if any of the items described here apply to your situation?

                                        Check to see if the path and file actually exist.

                                          @Danp I'll take a look for the file first thing tomorrow when I'm back at the office, I have some errands I have to run this afternoon.

                                            I don't have the VHD (20161214T030158Z_delta.vhd) listed from the 14th (it's at my rotation schedule) so that doesn't mean much...

                                            Once the dates are fixed testing this will be a bit easier.
