Why your KubeVirt VMs can’t move between clusters — and how EVPN fixes it
KubeVirt VMs cannot move between clusters due to a limitation in the current implementation. However, EVPN (Ethernet VPN) can fix this issue by providing a solution for inter-cluster VM migration.

KubeVirt VMs are unable to move between clusters due to a limitation in the current implementation. EVPN, a solution for inter-cluster VM migration, can fix this issue.
Imagine you have a virtual machine that you want to move from one computer to another. But, the computer it's on can't talk to the other computer. EVPN is like a special messenger that helps the two computers talk to each other, so you can move the virtual machine from one computer to the other.
Analysis
Background
KubeVirt is a project that aims to bring virtual machines to Kubernetes. It allows users to run virtual machines on top of a Kubernetes cluster, providing a more traditional virtualization experience. However, one of the limitations of KubeVirt is that it does not support the migration of virtual machines between different clusters.
The Problem
The inability to move KubeVirt VMs between clusters is a significant limitation for users who need to migrate workloads between different clusters. This is because KubeVirt VMs are tied to a specific cluster and cannot be moved to another cluster without being recreated.
EVPN: A Solution for Inter-Cluster VM Migration
EVPN (Ethernet VPN) is a solution that can fix this issue. EVPN is a network virtualization technology that allows for the creation of virtual networks on top of a physical network. It provides a solution for inter-cluster VM migration by allowing VMs to be moved between different clusters without being recreated.
How EVPN Works
EVPN works by creating a virtual network on top of a physical network. This virtual network is then used to connect VMs between different clusters. When a VM needs to be moved between clusters, EVPN creates a new virtual network connection between the two clusters, allowing the VM to be moved without being recreated.
Benefits of EVPN
EVPN provides several benefits for users of KubeVirt. It allows for the migration of VMs between different clusters, making it easier to manage workloads across different clusters. It also provides a more flexible and scalable solution for inter-cluster VM migration.
Conclusion
In conclusion, EVPN is a solution that can fix the limitation of KubeVirt VMs not being able to move between clusters. It provides a solution for inter-cluster VM migration, making it easier to manage workloads across different clusters. With EVPN, users of KubeVirt can now migrate VMs between different clusters without being recreated, making it a more flexible and scalable solution for inter-cluster VM migration.
Key points
- KubeVirt VMs cannot move between clusters due to a limitation in the current implementation.
- EVPN provides a solution for inter-cluster VM migration.
- EVPN creates a virtual network on top of a physical network to connect VMs between different clusters.
- EVPN allows for the migration of VMs between different clusters without being recreated.
If EVPN is successfully implemented, it could lead to a more flexible and scalable solution for inter-cluster VM migration. This could make it easier for users to manage workloads across different clusters, leading to increased productivity and efficiency.
However, the implementation of EVPN may face challenges, such as compatibility issues with existing infrastructure and the need for significant changes to the current KubeVirt implementation.
