Why your KubeVirt VMs can’t move between clusters — and how EVPN fixes it
TL;DR
KubeVirt enables live migration of VMs across Kubernetes clusters, but maintaining IP and MAC addresses requires a stretched Layer 2 network, complicating the process. EVPN technology can simplify this by eliminating the need for extensive network reconfiguration.
✦ Why It Matters
Consider implementing EVPN to facilitate easier VM migrations between Kubernetes clusters today.
Key Takeaways
- Use EVPN to simplify VM migration between clusters.
- Manage network configurations through Kubernetes CRDs.
- Eliminate reliance on network teams for VM mobility.
- Implement a dedicated migration network to avoid congestion.
How It Works
EVPN creates an overlay network that allows VMs to maintain their IP and MAC addresses during migration. OpenPERouter manages this through CRDs, enabling Kubernetes administrators to configure L2 domains and dedicated migration paths without physical network changes.
