VPS ON – pridani dummy0 sitoveho rozhranni

Pouzivam VPS ON s Debian 9. Potreboval bych pridat dummy0 interface a nastavit mu statickou IP. Ve vychozim stavu nebezi systemd-networkd, takze novy interface by mel jit pridat pres /etc/network/interfaces prip. /etc/network/interfaced.d/xxx.cfg

/etc/network/interfaces je pri kazdem startu prepsany (zrejme Open Nebula), takze jsem vytvoril /etc/network/interfaces.d/dummy.cfg:

auto dummy0

iface dummy0 static inet

address=x.x.x.x

netmask=x.x.x.x

..zaroven jsem do /etc/modules-load.d/modules.conf pridal radek:

dummy

..aby se pri startu nacetl potrebny kernel modul.

Bohuzel toto nezafungovalo, v logu jsem nasel hlasku:

Jul 28 22:50:34 debian one-contextd[767]: Device „dummy0“ does not exist.
Jul 28 22:50:34 debian one-contextd[767]: Cannot find device „dummy0“
Jul 28 22:50:34 debian one-contextd[767]: ifup: failed to bring up dummy0

…jako by nebyl zavedeny ten kernel modul.

Zapnuti systemd-networkd a konfigurace pres networkd funguje (i bez upravy modules.conf), ale zajimalo by mne, kde je problem s prvnim resenim. Zda se neda obejit bez networkd.

Vse opet nejak souvisi s kontextualizaci…
