Functions

func CPUManagerEnabled

func CPUManagerEnabled() bool

func Clear

func Clear()

func DataVolumesEnabled

func DataVolumesEnabled() bool

func HypervStrictCheckEnabled

func HypervStrictCheckEnabled() bool

func IgnitionEnabled

func IgnitionEnabled() bool

func Init

func Init()

We cannot rely on automatic invocation of 'init' method because this initialization code assumes a cluster is available to pull the configmap from

func InitFromConfigMap

func InitFromConfigMap(cfgMap *k8sv1.ConfigMap)

func LiveMigrationEnabled

func LiveMigrationEnabled() bool

func SRIOVEnabled

func SRIOVEnabled() bool

func SupportedEmulatedMachines

func SupportedEmulatedMachines() []string

Types

type ClusterConfig

type ClusterConfig struct {
	// contains filtered or unexported fields
}

func NewClusterConfig

func NewClusterConfig(configMapInformer cache.Store, namespace string) *ClusterConfig

NewClusterConfig represents the `kubevirt-config` config map. It can be used to live-update values if the config changes. The config update works like this: 1. Check if the config exists. If it does not exist, return the default config 2. Check if the config got updated. If so, try to parse and return it 3. In case of errors or no updates (resource version stays the same), it returns the values from the last good config
