In kde, but I think it doesn't matter. How did you get it installed?

How did you get it installed? Have you tried mounting the images?

As such, depending on the configuration (i.e. if CDEmu daemon is to be run in session, non-root mode), it might be a good idea to include an udev rule to set up appripriate permissions. E.g.:
KERNEL=="vhba_ctl", NAME="%k", MODE="0660", OWNER="root", GROUP="cdrom" For example in arch: https://www.archlinux.org/packages/community/i686/vhba-module/
View the file list for vhba-module: ... usr/lib/udev/rules.d/60-vhba.rules
+ https://www.archlinux.org/packages/community/i686/cdemu-daemon/
.... usr/lib/systemd/system/cdemu-daemon.service ...
cdemu-daemon is supposed to be run as user.
# modprobe -r vhba # cd /etc/udev/rules.d/ # mv 60-vhba.rules 60-vhba.rules.backup # modprobe vhba ~> /usr/bin/cdemud Starting daemon in local mode with following parameters: - num devices: 1 - ctl device: /dev/vhba_ctl - audio driver: null - bus type: session cdemu0: Device: failed to open control device /dev/vhba_ctl! cdemud: Daemon: failed to initialize device 0! Daemon initialization failed: Device initialization failed. # modprobe -r vhba # mv 60-vhba.rules.backup 60-vhba.rules # modprobe vhba ~> /usr/bin/cdemud Starting daemon in local mode with following parameters: - num devices: 1 - ctl device: /dev/vhba_ctl - audio driver: null - bus type: session In other console: ~> cdemu status Devices' status: DEV LOADED FILENAME 0 0 N/A
There is no udev rule file by default because that is a site-specific security decision. Some users may want 0666, others may want {0660 with a cdemu group}.
Therefore it is necessary to find a compromise. I think a normal user should not: /sbin/yast2 sysconfig set MODULES_LOADED_ON_BOOT="vhba" touch /etc/udev/rules.d/60-vhba.rules -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
