- Shared mount point for KVM XML configuration files at /etc/libvirt
- At least four nodes to create HA cluster with Virtualizor KVM (to get reliable quorum) includes Virtualizor master.
- Shared IPPool among the HA Server group, so that the same IP can work on the other server where VM will get migrated on failure.
- Since Version 2.9.9+
- Login to the Virtualizor Master with the servers root details
- Click on Servers ->Add Server Groups and check the High Availability checkbox to enable High Availability for the Server Group.
