Summary
Neutron Integration (Tech Preview) + various new enhancements - click for details
Details
New in RHV 3.3. is the initial (tech preview) support for OpenStack Neutron as a network provider on Red Hat Virtualization Manager. OpenStack Neutron can provide networking capabilities for consumption by hosts and virtual machines.
The integration includes:
• Advanced engine for network configuration.
• open vSwitch distributed virtual switching support.
• Ability to centralize network configurations with Red Hat Enterprise Linux OpenStack Platform (not included).
RHV 3.4 extended the integration with Neutron as follows:
• Leverage Neutron IPAM by configuring subnets on external networks.
• Apply Neutron security groups to VM interfaces by assigning the "SecurityGroups" custom property to relevant vNIC Profiles.
RHV 3.5 introduces a Neutron virtual appliance, to more easily get up-and-running with a Neutron server.
Also new in 3.3. are the following network features:
- simplified management network setup procedure
- New migration network role ( grant the migration role to a cluster network, separating migration data to the designated migration network, to prevent migration traffic from choking other networks)
- Virtual machine NIC-specific parameters (this enables a range of connection options, including: Create a host NIC via Mellanox UFM and connect it directly to a virtual NIC; use OpenStacks Neutron to connect a virtual NIC to one of its defined networks; pass non-standard quality of service (QoS) settings for a virtual NIC)
- Network QoS using virtual NIC profiles (users can now limit the inbound and outbound network traffic on a virtual NIC level by applying profiles which define attributes such as port mirroring, quality of service (QoS) or custom properties)
- Multiple network gateways per host (define a gateway for each logical network on a host)
- Refresh host network configuration (allows the administrator to obtain updated network configuration such as available NICs)
- Improved bond support (add new bonds from the administration portal, in addition to the five predefined bonds for each host
New in 3.4:
- Automatic propagation of network attribute changes to active hypervisors (instead of having to synchronize each host manually).
- Network labels to ease complex hypervisor networking configurations, comprising many networks.
- Predictable vNIC ordering inside guest OS for newly-created VMs.
- Hypervisors now recognize hotplugged network interfaces.
New in 3.5:
- Notifications in case of bond/NIC changing link state (e.g. link failure).
- Ability to configure custom properties on hypervisor network devices; specifically configuring advanced bridge and ethtool options.
- Support for bigger MAC address ranges.
- Dedicated network connectivity log on hypervisors to ease investigation in case of "disaster".
- Add a warning when unplugging a vNIC.
- Add warnings when meddling with the display network.
- Properly display arbitrarily-named hypervisor VLAN devices in the management console.
Advanced networking can also be achieved with RHEL OpenStack Platform. Starting with Red Hat Enterprise Linux 6.4, the Open vSwitch kernel module is included as an enabler for Red Hat Enterprise Linux OpenStack Platform. Open vSwitch is only supported in conjunction with Red Hat products containing the accompanying user space packages. Without theses packages, Open vSwitch will not function.
