Configure 1G Hugepages in OpenShift 4.2

Update Node Kernel Parameters

Supporting 1G hugepages requires the Kernel to support 1G Hugepages. This is done by applying a boot Kernel parameter.

• Create a MachineConfig (MC) to apply to the Node type that will be using the 1G hugepages. The following example set 1G hugepages for all worker nodes 50-kargs-1g-hugepages.yaml:

  apiVersion: machineconfiguration.openshift.io/v1
  

kind: MachineConfig

Simulate Bare-Metal IPMI for VMs in RHEL8 Libvirt

• Install the Virtual BMC package in the machine to use as the vBMC server. Note1: When using OpenStack repos the python3-virtualbmc RPM might be available. These instrucctions do not use that package.

  pip3 install virtualbmc
  

  • The vBMC server can be running in any machine. When using a remote libvirt server it is recommended to have passwordless authentication from the vBMC server to the libvirt machines.
  • For this document the vBMC Server export vBMCServerIP=192.168.1.13
