OpenShift Virtualization Async DR (VolSync + Ansible)

This repo provides role-based playbooks to configure asynchronous DR for KubeVirt VMs using VolSync and optionally MetalLB.

Key capabilities:

• Install required operators (VolSync and optional MetalLB).
• Discover VM disks → create ReplicationSource (source) and ReplicationDestination (dest).
• Schedule periodic syncs (every X minutes).
• Automatically pick up new VM disks with a re-scan.
• Capture sanitized VM definitions from the source and store them on the destination for exact restoration (same CPU, memory, devices, interfaces, MACs).
• Failover workflow pauses RD, then restores the same VM spec at the DR site, pointing disks to the correct PVCs.

Works with Ansible Core and AWX.

Prereq

dnf install ansible-core git python3-pip
