Functions

func AttachHostDevices

func AttachHostDevices(dom deviceAttacher, hostDevices []api.HostDevice) error

func CreateHostDevices

func CreateHostDevices(vmi *v1.VirtualMachineInstance) ([]api.HostDevice, error)

func CreateHostDevicesFromIfacesAndPool

func CreateHostDevicesFromIfacesAndPool(SRIOVInterfaces []v1.Interface, pciAddrPool pool) ([]api.HostDevice, error)

func DifferenceHostDevicesByAlias

func DifferenceHostDevicesByAlias(desiredHostDevices, actualHostDevices []api.HostDevice) []api.HostDevice

DifferenceHostDevicesByAlias given two slices of host-devices, according to Alias.Name, it returns a slice with host-devices that exists on the first slice and not exists on the second.

func FilterHostDevices

func FilterHostDevices(domainSpec *api.DomainSpec) []api.HostDevice

func GetHostDevicesToAttach

func GetHostDevicesToAttach(vmi *v1.VirtualMachineInstance, domainSpec *api.DomainSpec) ([]api.HostDevice, error)

func SafelyDetachHostDevices

func SafelyDetachHostDevices(domainSpec *api.DomainSpec, eventDetach eventRegistrar, dom deviceDetacher, timeout time.Duration) error

Types

type PCIAddressPool

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

func NewPCIAddressPool

func NewPCIAddressPool(ifaces []v1.Interface) *PCIAddressPool

NewPCIAddressPool creates a PCI address pool based on the provided list of interfaces and the environment variables that describe the SRIOV devices.

func (*PCIAddressPool) Pop

func (p *PCIAddressPool) Pop(networkName string) (string, error)

Pop gets the next PCI address available to a particular SR-IOV network. The function makes sure that the allocated address is not allocated to next callers, whether they request an address for the same network or another network that is backed by the same resourceName.
