Functions

func CPUFeatureLabelsFromCPUFeatures

func CPUFeatureLabelsFromCPUFeatures(vmi *v1.VirtualMachineInstance) []string

func CPUModelLabelFromCPUModel

func CPUModelLabelFromCPUModel(vmi *v1.VirtualMachineInstance) (label string, err error)

func GetMemoryOverhead

func GetMemoryOverhead(vmi *v1.VirtualMachineInstance, cpuArch string) *resource.Quantity

GetMemoryOverhead computes the estimation of total memory needed for the domain to operate properly. This includes the memory needed for the guest and memory for Qemu and OS overhead.

The return value is overhead memory quantity

Note: This is the best estimation we were able to come up with

and is still not 100% accurate

func HaveContainerDiskVolume

func HaveContainerDiskVolume(volumes []v1.Volume) bool

func HaveMasqueradeInterface

func HaveMasqueradeInterface(interfaces []v1.Interface) bool

func SetNodeAffinityForForbiddenFeaturePolicy

func SetNodeAffinityForForbiddenFeaturePolicy(vmi *v1.VirtualMachineInstance, pod *k8sv1.Pod)
