KVM を Ovirt (Web UI) で管理

Posted at

What's this?

KVM 管理を「コマンドラインの virsh」や「Linux X Application の VirtManager」ではなく、普通にブラウザで管理したい。
RHEV(RedHat Enterprise Virtuaalizaiton) の Upstream の Ovirt で、KVM Host を Ovirt 管理化に設定するまでのメモ

  • Install/Setup oVirt Engine (Ovirt Server)
  • Install/Setup Vdsm-Node (KVM node)
  • Connect Vdsm-Node (KVM node) to oVirt Engine (Ovirt Server)

Install/Setup oVirt Engine (Ovirt Server)

oVirt Engine is the control center of the oVirt environment.
