Functions

func CloseIOAndCheckErr

func CloseIOAndCheckErr(c io.Closer, err *error)

CloseIOAndCheckErr closes the file and check the returned error. If there was an error a log messages will be printed. If a valid address (not nil) is passed in err the function will also update the error Note: to update the error the calling funtion need to use named returned variable (If called as defer function)

func IsGPUVMI

func IsGPUVMI(vmi *v1.VirtualMachineInstance) bool

Check if a VMI spec requests GPU

func IsHostDevVMI

func IsHostDevVMI(vmi *v1.VirtualMachineInstance) bool

Check if a VMI spec requests a HostDevice

func IsSRIOVVmi

func IsSRIOVVmi(vmi *v1.VirtualMachineInstance) bool

func IsVFIOVMI

func IsVFIOVMI(vmi *v1.VirtualMachineInstance) bool

Check if a VMI spec requests a VFIO device

func IsVMIVirtiofsEnabled

func IsVMIVirtiofsEnabled(vmi *v1.VirtualMachineInstance) bool

Check if a VMI spec requests VirtIO-FS

func ParsePciAddress

func ParsePciAddress(pciAddress string) ([]string, error)

ParsePciAddress returns an array of PCI DBSF fields (domain, bus, slot, function)

func ResourceNameToEnvVar

func ResourceNameToEnvVar(prefix string, resourceName string) string

func WriteBytes

func WriteBytes(f *os.File, c byte, n int64) error
