This feature is actively developed. It might significantly change in the future.

The module is not enabled by default in any bundles.

How to explicitly enable the module…

Note that the configOverrides parameter of the InitConfiguration resource is used when installing Deckhouse, not ModuleConfig.

Set the virtualizationEnabled: true or virtualizationEnabled: false in the configOverrides parameter to explicitly enable or disable the module when installing Deckhouse.

Use the virtualization section of the configOverrides parameter to configure the module when installing Deckhouse.

Set the spec.enabled module parameter to true or false to explicitly enable or disable the module.

Example of enabling the virtualization module:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: virtualization
spec:
  enabled: true

Example of disabling the virtualization module:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: virtualization
spec:
  enabled: false

Note! Module depends on the cni-cilium module. Make sure your cluster is deployed with Cilium as the main CNI plugin.

If cilium works in tunnel mode, enabling this module will result in short downtime due to reconfiguration of overlay network to a non-standard VXLAN port.

Note! Module requires kernel version >= 5.7.

You will also need to specify one or more desired subnets from which IP addresses will be allocated to virtual machines:

vmCIDRs:
- 10.10.10.0/24

The subnet for the VMs should not conflict with the subnet for the pods and the subnet for the services

The module is configured using the ModuleConfig custom resource named virtualization (learn more about setting up Deckhouse…).

Example of the ModuleConfig/virtualization resource for configuring the module:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: virtualization
spec:
  version: 1
  enabled: true
  settings: # <-- Module parameters from the "Parameters" section below.

Parameters

Schema version: 1

  • highAvailabilityboolean

    Manually enable the high availability mode.

    By default, Deckhouse automatically decides whether to enable the HA mode. Click here to learn more about the HA mode for modules.

    Examples:

    highAvailability: true

    highAvailability: false
  • vmCIDRsarray of strings

    Required value

    List of CIDRs used to allocate static IP addresses for Virtual Machines.

    Example:

    vmCIDRs:
- 10.10.10.0/24
- 10.10.20.0/24
