      Cause: The OVS network is configured before the kdump service generates its special initramfs. When the kdump service starts, it picks up the network-manager configuration files and copies them into the kdump initramfs.

      Consequence: When the node reboots into the kdump initramfs, the kernel crash dump upload over the network fails because OVN does not run into the initramfs and the virtual interface is thus not configured.

      Fix: The ordering was changed to ensure that kdump starts and builds the kdump initramfs before the OVS networking configuration is set up.

      Result: Kdump use the proper network configuration in the initramfs and the kernel crash dump is exported to the remote destination.

    • Done

      kdump crash logs are not created to the SSH remote when OVN is configured.
