KVM High Availability Regardless of Storage - CloudStack European User Group Virtual, May 2021

Apache Cloudstack VP - Gabriel Beims Bräscher – talking about KVM High Availability Regardless of Storage. One of the great advantages of CloudStack is that it is vendor-independent, meaning you can decide the technology stack above and below based on your experience or needs. Having High Availability enabled for KVM hosts can improve greatly the QoS by handling (fence/recover) a problematic Host as well as re-starting its stopped VMs on healthy hosts. However, there is a limitation on CloudStack HA for KVM - it relies mainly on NFS heartbeat script checks. Gabriel’s talk illustrated how CloudStack HA works for KVM hosts and presented a way of improving its implementation in a way that KVM HA works with any storage system pluggable on KVM, not just NFS.

CloudStack European User Group Virtual happened on May 27th. The first CSEUG Virtual proved to be a huge success. It collected people from 23 countries – Germany, the United Kingdom, Switzerland, India, Bulgaria, Greece, Poland, Serbia, Brazil, Chile, Russia, USA, Canada, Japan, France, Uruguay, Korea …
We also had a record number of registrations and attendees for a CloudStack User Group Event. The physical distance was not a stopper for our speakers, who joined the event from 6 different countries.

I can't see the new HA feature in 4.16, or 4.16.1 - do you know when we can get access to it?
