yum --showduplicates list openvswitch

baseurl=https://s3-us-west-1.amazonaws.com/platform9-neutron/el7/$basearch/

1. Update OVS package.

yum update openvswitch

1. Restart the pf9-neutron-ovs-agent service subsequently.

service pf9-neutron-ovs-agent restart

To install python36-libvirt required for Nova Compute role, install epel-release package.

yum install epel-release -y

For Ubuntu hosts:

1. Run the following commands to list GPG keys. If the “Platform9 Systems” key is visible in the output, please skip to Step #3.

gpg -k

gpg -K

Bug Fixes and Improvements

• Added pre-requisites checking to VM-HA api so as to disallow enabling HA on host aggregates with less than 4 hosts or when any host is offline at the time of enabling HA itself.
• Fixed an issue where Cinder was not filtering Glance endpoints by region name at the time of volume creation leading to timeouts.
• Fixed an issue where keystone client used by nova, cinder and ceilometer services on hosts were not using the proxy, despite comms service being configured to reach the control plane via a proxy server.
• Fixed an issue where VMWare discovery service would fail to parse special characters in VC password.
• Fixed an issue with Aodh due to missing keystone domain id in service configuration when notifying gnocchi-based alarms’ action.
• Fixed an issue with soft-deleting VMs booted from volumes where volume would continue to be in attached state even if VM is deleted.
• Fixed an issue with stale allocations for a resource provider in nova placement database that would prevent deletion of that RP and corresponding compute service during hypervisor role de-authorization.
• Fixed an issue with VM-HA where rabbitmq queue keeps growing for a host when it is removed from the HA cluster.
• Fixed a bug that allowed users to migrate VMs to hosts outside of their allocated availability zone.
• Added a warning message to inform users that at least three hosts are required to configure OpenStack High Availability

Upgrade Notes

Deprecated Ceilometer-API

Starting with this Platform9 release, the deprecated ceilometer-api is disabled in favor of using equivalent APIs provided by Gnocchi, Aodh and Panko services for metrics, alarms and events respectively. With this change, any references to native ceilometer metrics should be dropped from Aodh alarms and Heat stack templates. You should transition to using Gnocchi-based alarms for autoscaling feature.

Updated Ubuntu Repository

Updated existing ubuntu_latest repo with signing of files using gpg key. Download key from s3 bucket using following

wget -q -O - https://platform9-neutron.s3-us-west-1.amazonaws.com/ubuntu_latest/key.gpg | sudo apt-key add - Debian path in /etc/apt/sources.list.d/platform9*.list should be modified to following add-apt-repository 'deb http://platform9-neutron.s3-website-us-west-1.amazonaws.com/ubuntu_latest /' apt-get update

VMware Appliance Added below annotation in VMware appliance template OVF suggesting it is used as Platform9 Gateway to avoid accidental deletion. <Annotation>openstack-do-not-delete:Platform9-VMware-Gateway</Annotation>
