- 2. Introduction OpenNebula approach to vCenter integration OpenNebula.systems
- 3. OPENNEBULA FEATURES FEATURES FOR VIRTUAL INFRA MANAGEMENT AND CLOUD ORCHESTRATION KVM Xen Virtual Infra Management •Capacity management •Multi-VM management •Resource optimization •HA and business continuity OpenNebula Cloud Management •VDC multi-tenancy •Simple cloud GUI and interfaces •Service elasticity/provisioning •Federation/hybrid vCenter VMware OpenNebula OpenNebula.systems
- 5. KEY POINTS OpenNebula.systems ● Seamless integration ● Leverages vMotion, HA, DRS scheduling… ● OpenNebula provides multi-tenant, cloud-like provisioning layer, benefiting from quotas, etc. ● Maintain VMware management tools, procedures and workflows ● Virtual Machines are deployed using Templates that already exist in vCenter. ● Access a vCenter server that manages one or more ESX Clusters.
- 6. KEY POINTS OpenNebula.systems ● Access a vCenter server that manages one or more ESX Clusters. ● Each vCenter Cluster is represented as an aggregated hypervisor: ○ OpenNebula chooses the vCenter Cluster ○ VMware DRS chooses the ESX Host ● After being instantiated with OpenNebula it can be managed either with OpenNebula (add/remove NICs, control life-cycle) or through vCenter (OpenNebula will poll).
- 8. REQUIREMENTS OpenNebula.systems ● vCenter 5.5, 6.0 and 6.5. ● At least one cluster with at least one ESX 5.5, 6.0 or 6.5 host. ● VMware tools in the guest OS. ● vCenter user for OpenNebula ● ESX Hosts in a Cluster must share a Datastore ● DRS is strongly recommended ● VNC is supported
- 9. WORKFLOW OpenNebula.systems ● Import vCenter Cluster (OpenNebula Host) ● Import or Create Networks. IP range and VLAN. ● Import vCenter Template ○ Creates Networks ○ Creates Images ○ Creates Datastores ● Update Template (Optional) ○ Add disks, nics, context, etc. ● Instantiate VM ○ Disk Resize, etc...
- 11. GOAL OF OPENNEBULA 5.4 OpenNebula.systems Up to speed with
- 14. STORAGE OpenNebula.systems ● System Datastores. OpenNebula chooses the target datastore (replacing Storage DRS!) ● Persistent & Non-persistent images ● Volatile disks ● Disk Resize upon instantiation ● Linked clones: faster deployment times, smaller disk usage ● Unmanaged disks ● Storage DRS support extended (Volatile & Persistent disks) ● Whole plethora of operations
- 19. NETWORKING OpenNebula.systems ● Manage Networks, not just consume them ● Create Networks (Port Groups) in vCenter ● Works for standard or distributed switches ● It can also create Switches if PHYDEV is specified (vmnic1, …) ● Configure the underlying network dynamically. Including VLAN IDs. ● Provide isolation dynamically.
- 22. SPEED OpenNebula.systems ● Rewrite of the monitorization routines ● New caching component for vCenter resources ● Rapid access to vCenter objects ● Pre-migrator to ease OpenNebula upgrades Overall improvement by 2 orders of magnitude!
- 23. OpenNebula 5.4 vCenter Improvements Fixing Limitations OpenNebula.systems
- 24. FIXING LIMITATIONS OpenNebula.systems ● Attach / Detach poweroff state ● Choose in what folder VMs will be placed ● Context regeneration ● Resources with spaces (including cluster names) ● Proper cleanup of terminated VMs after poweroff ● Recover delete cleans all resources ● VNC is configured automatically for Wild VMs
