Description katnatek 2023-03-04 19:12:11 CET

Description of problem:

I try to use cdemu to mount a iso image and nothing happen
Running dolphin from console i get

ERROR: Failed to acquire daemon interface version (this most likely means your daemon is out-of-date): g-dbus-error-quark: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name net.sf.cdemu.CDEmuDaemon was not provided by any .service files (2)

Try to run the daemon and i get

cdemu-daemon 
Starting CDEmu daemon with following parameters:
 - config file: (null) (exists: 0)
 - num devices: 1
 - control device: /dev/vhba_ctl
 - audio driver: null
 - bus type: session
 - default CDEmu debug mask: 0x0
 - default libMirage debug mask: 0x0

Using cross-namespace EXTERNAL authentication (this will deadlock if server is GDBus < 2.73.3)cdemu0: Kernel I/O: failed to open control device /dev/vhba_ctl: No existe el fichero o el directorio!
cdemu: Daemon: failed to start device #0!
cdemu: Daemon: failed to create device!
Daemon initialization and start failed!

So finally i "su -" and confirm the /dev/vhba_ctl is missing

ls /dev/vh*
/dev/vhci  /dev/vhost-net  /dev/vhost-vsock

modprobe vhba
ls /dev/vh*
/dev/vhba_ctl  /dev/vhci  /dev/vhost-net  /dev/vhost-vsock

So finally i can run cdemu-daemon and mount my iso images with cdemu

I suppose the module should be loaded when you clean install the package but not happen, i have to explicit load them

Comment 3 Dave Hodgins 2023-03-27 02:30:15 CEST

Closing as invalid. The vhba kernel module is useless by itself, so just
installing the dkms package for it does not cause it to be loaded. It does
get loaded if cdemu-daemon is installed.

[root@x9v ~]# grep vhba /proc/modules
[root@x9v ~]# urpmi cdemu-daemon

Comment 4 katnatek 2023-03-27 06:20:06 CEST

(In reply to Dave Hodgins from comment #3)

For get the behaviour you get i did have to uninstall cdemu-daemon cdemu-clien anmd dkms-vhba the reinstall cdemu-client

BTW dud you take care of check if at next reboot the module load?
I do and its no so

Status: RESOLVED => REOPENED
Resolution: INVALID => (none)

Comment 5 Dave Hodgins 2023-03-27 08:41:48 CEST

Ah, correct. While the module does get loaded during installation of
cdemu-daemon, it doesn't get loaded after rebooting.

Moving /etc/modprobe.preload.d/cdemud.conf to /etc/modules-load.d/ works to
get it loaded during boot.

Comment 6 Dave Hodgins 2023-03-27 08:54:09 CEST

Reassigning to David Geiger as the person who made the most recent changes
to cdemu-daemon.

Comment 7 katnatek 2023-03-27 19:44:10 CEST

Updated packages fix the issue, the module load when the package install and when you reboot, i don't remember if previously was necessary  manually add cdemu-daemon to start process of the desktop, but that is a minor thing

Resolution: (none) => FIXED
Status: REOPENED => RESOLVED
