Thank you xnox. I confirm that this works with chzdev -d/-e and with reboot. @Asha, this is a better solution for you. ------- Comment From wint...@de.ibm.com 2021-02-25 10:36 EDT------- (In reply to comment #26) > My preference would be to fix networkd, if that fails netplan, and isc-dhcp > only if there is syntax to online the device in the right l2/l3 state via > kernel cmdline and that one needs to complete install over it. > > For example, does automatic chzdev device enablement provides > autoconfiguration for hipersockets in l3? in that case it would be neat for > ip=dhcp to just do the right thing. > Yes, 'chzdev -e' defaults to Layer3 unless you explicitely specify 'chzdev -e layer2=1'.
