VIO 2.0 Product Compatibility Matrix

VMware changes in OpenStack “Kilo” (2015.1.0)

Support for Ephemeral disks

– http://specs.openstack.org/openstack/nova-specs/specs/kilo/approved/vmware-ephemeral-disk-support.html

Support for VSAN

– http://specs.openstack.org/openstack/nova-specs/specs/kilo/implemented/vmware-vsan-support.html

Support for OVA based images

– http://specs.openstack.org/openstack/nova-specs/specs/kilo/implemented/vmware-driver-ova-support.html

Support for SPBM based storage policies

– http://specs.openstack.org/openstack/nova-specs/specs/kilo/implemented/vmware-spbm-support.html

The capability to run multiple vmware clusters from a single nova-compute service via the vmware.cluster_name config option is deprecated in Kilo and may be removed in Liberty. See: https://review.openstack.org/#/c/163426/

VIO 2.0 New Features

Ceilometer with Heat

Service Management

LBasS

Separate Metadata with Management network

Certificate Update

Hyperic Integration

What is Ceilometer ?

Ceilometer is telemetry service for openstack, it gathers usage data from various openstack services, and we use the data to provide input for heat to do auto-scaling decisions.

Service Management (Start/Stop/Restart)

LBaaS

• VIO 2.0 Support LBaaS v1

– No change in VIO installation

– LBaaS leverage Edge Appliance LB Feature

152982CF-108F-47A6-B86A-0F0F6A56D628.html

http://www.routetocloud.com/2014/10/nsx-load-balancing/

– Use compact edge(Memory:512M,Disk:512M,vCPU:1)

Separate Edge network & Management network

• VIO 2.0 support new network topology

– The Management, Compute and Edge clusters are not all connected to the

same Virtual Distributed Switch (VDS)

– The Management, Compute and Edge clusters are not all L2 adjacent.

Generate CSR file

Hyperic Agent Installation & Management

• vRealize Hyperic provides performance management with complete, constant visibility into applications and infrastructure.

• The OpenStack Management pack collects data from OpenStack APIs, through a Hyperic agent for OpenStack Process data, and correlates OpenStack tenant and inventory information with vSphere and NSX Management Packs.MP link: https://solutionexchange.vmware.com/store/products/management-pack-for-openstack-1-5#.VcgeEBOqqkp

• For better user experience, a new feature is ready to install and manage Hyperic agents to openstack control plane VMs

Upgrade to VIO 2.0

Overview

Customers who have deployed a OpenStack cloud using VIO 1.x product are running OpenStack “Icehouse” code.

With the VIO 2.0 product we moved to use the OpenStack “Kilo” code.

The “Upgrade” feature allows users running “Icehouse” deployment to upgrade to “Kilo” deployment.

Also, in the process if they fail they can rollback to the “Icehouse” based deployment

Backup & Restore

Advantages over competitive products

• Fully integrated with VIO – no other 3rd party software installation required

• Single CLI command to do backup and recovery

• OpenStack Awareness – ensure OpenStack services restarted correctly after recovery

• Non disruptive OpenStack database backup – services are fully functional during backup with consistency

Backup and Recovery

• Backup the OpenStack database

• Restore the OpenStack database

• Backup the management server

• Restore the management server

• Recover nodes from OpenStack control plane

Glance - Image ConversionExperimental Feature

Glance – Image Conversion (Experimental)

* - Available only if the image is OVA

• Users migrating from KVM based cloud have QEMU2 / RAW images.

• Running qemu-img on each of them and uploading them with the right disk & adapter types is time-consuming and error-prone.

• Glance now natively supports image conversion

• Only supported on Location based Image Uploads

• Conversion is a heavy process and hence need to queue them.

• Due to technical limitation on glance-api we cannot support conversion when uploading from local system.

• Image Creation Workflow

• You will see additional disk formats if you choose “Image Locations” in the Image Creation Form.

• A Task is queued for every conversion operation and you can monitor the status of conversion.

Glance – Image Conversion (contd.)

* - Available only if the image is OVA

• Supported Source Formats

• All formats supported by qemu-img utility

• i.e qcow2, raw, vhd, vdi

• Destination Format (Fixed in 2.0)

• VMDK

• vmware_disktype – sparse

• Vmware_adaptertype – lsiLogic (currently ide – but will be changed before RC)

• Troubleshooting

• We use /mnt/data/glance_tmp on controllers for temporary conversion purposes.

• There is a possibility of running out of disk space with large disks. Hence, this needs a bit of caution and hence will be experimental in 2.0.

• In future versions, the conversion may be offloaded to another worker VM.
