Some time ago, the tun module was automatically loaded during boot. Today, it is no more (systemd related change?).
I'd like to know to know the answer to that question before making any changes to libvirt. But I'm not sure who to ask. Do you have any suggestions Stefan? Anyone else know who could explain why the tun module is no longer loaded, and best practices for apps to handle that? Perhaps I just need to add something to the libvirtd systemd service file?? -- 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.

I think that today /usr/lib/modules-load.d is the way to go if we want a module to be always loaded. *if* there is a useful libvirt setup that does not need tun, then modifying libvirt to check for availability of tun and loading it on demand would be an option, but I personally think that it is overkill. -- 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.
