OpenNode OS migration to softraid (live)

If in need to migrate OpenNode OS from single disk installation (no hardware raid) to linux software raid setup (RAID1) - please use this recipe. Conversion can be done online without much interrupting server operations besides a bit reduced disk IO.

OpenNode OS CD install

  • Download and burn OpenNode OS ISO installer image
  • Boot server from OpenNode OS install CD
  • Follow installer on-screen instructions
  • Choose automatic partitioning (if server has hardware RAID or RAID is not needed). Automated partitioning creates all needed partitions and LVM volumes on servers first harddisk or RAID disk - if server has several harddisks or RAID disks and there is a need to spread initial partitions over these then manual partitioning is needed (or migrating LVM volumes later manually).
  • Choose automatic partitioning with softraid setup (if server has no hardware raid and softraid setup is desired)
  • Follow installer on-screen instructions to complete the installation and reboot

KVM VM management with virt-manager GUI

This howto is about using standard virt-manager GUI tool for KVM VM management. In its current state virt-manager is not capable of fully managing OpenVZ linux containers - so it’s mainly a alternative GUI tool for doing KVM VM management with OpenNode OS - and not supporting all features that OpenNode OS may have. However we try to make virt-manager user experience as smooth as we can by pre-configuring libvirt for OpenNode related policies as much as possible.
