Introduction ​

Install the KubeVirt environment, including k3s + KubeVirt + network configuration + port forwarding as a complete set.

Add Swap Memory ​

TIP

Adding some swap prevents the host from running out of memory.

Unit conversion: entering 1024 creates 1GB of SWAP virtual memory. Virtual memory uses disk space. When actual memory runs out, virtual memory is used automatically, but this brings high I/O and CPU usage.

It is recommended to create swap no larger than twice the actual memory size.

shell
curl -L https://raw.githubusercontent.com/spiritLHLS/addswap/main/addswap.sh -o addswap.sh && chmod +x addswap.sh && bash addswap.sh

Environment Installation ​

  • Supported OS: Debian 11+, Ubuntu 20.04+
  • Automatically installs k3s (lightweight Kubernetes)
  • Automatically deploys KubeVirt operator and CDI (Containerized Data Importer)
  • Automatically configures Flannel network plugin and port forwarding
  • Automatically detects public IPv6 address and configures IPv6 network (if present)
  • Supports x86_64 and ARM64 architecture servers
shell
bash <(curl -sSL https://raw.githubusercontent.com/oneclickvirt/kubevirt/main/kubevirtinstall.sh)

TIP

After installation, it is recommended to run kubectl get pods -n kubevirt to verify that the KubeVirt environment is working correctly. All Pods should be in Running state.

WARNING

The k3s + KubeVirt installation takes some time (usually 5–15 minutes). Please run it inside a screen or tmux session to avoid installation failure due to SSH disconnection.

Uninstall KubeVirt Environment ​

One-click uninstall of the complete environment, including all virtual machines, k3s, KubeVirt, and auxiliary files:

shell
bash <(curl -sSL https://raw.githubusercontent.com/oneclickvirt/kubevirt/main/scripts/kubevirtuninstall.sh)

WARNING

The script will require you to enter yes to confirm before execution. This operation is irreversible. Content deleted includes all virtual machines, images, k3s and all KubeVirt components. Reset procedure: run uninstall first, then run install again to verify the entire installation process from scratch.
