I recently encountered a problem while deploying Openshift on Opennebula based VMs.
Because Opennebula uses contextualization, it disables network manager which in turn causes problems when Openshift tries to start the SDN pods (no cni found).
There were a couple of challenges but the one that buffed me the most was the NM_CONTROLLED=no which kept being set by the Opennebula contextualization feature which set’s up the networking configurations.
Go to line ~215 and and change:
cat <<EOT DEVICE=$DEV BOOTPROTO=static NM_CONTROLLED=no TYPE=Ethernet EOT
cat <<EOT DEVICE=$DEV BOOTPROTO=static NM_CONTROLLED=yes TYPE=Ethernet EOT
Mind you this will impair the contextualization process network wise so I would suggest doing this after the machine boots and you ready the node for installation.
