Functions

func CreateScratch

func CreateScratch(ctx context.Context, lcowUVM *uvm.UtilityVM, destFile string, sizeGB uint32, cacheFile string) error

CreateScratch uses a utility VM to create an empty scratch disk of a requested size. It has a caching capability. If the cacheFile exists, and the request is for a default size, a copy of that is made to the target. If the size is non-default, or the cache file does not exist, it uses a utility VM to create target. It is the responsibility of the caller to synchronise simultaneous attempts to create the cache file.
