Functions

func CPUFeatureLabelsFromCPUFeatures added in v0.15.0 

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

func CPUModelLabelFromCPUModel added in v0.11.1 

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

func GetMemoryOverhead added in v0.47.0 

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
