Functions

func AlignImageSizeTo1MiB added in v0.49.1 

func AlignImageSizeTo1MiB(size int64, logger *log.FilteredLogger) int64

AlignImageSizeTo1MiB rounds down the size to the nearest multiple of 1MiB A warning or an error may get logged The caller is responsible for ensuring the rounded-down size is not 0

func CalcExpectedMemoryDumpSize added in v0.56.0 

func CalcExpectedMemoryDumpSize(vmi *v1.VirtualMachineInstance) *resource.Quantity

func CloseIOAndCheckErr added in v0.36.0 

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.

func TranslateBuildArch() string

TranslateBuildArch translates the build_arch to arch 

case1:
  build_arch is crossbuild-s390x, which will be translated to s390x arch
case2:
  build_arch is s390x, which will be translated to s390x arch
