源码适配

kubevirt源码中包含的组件和工具较多，本次适配以制作kubevirt部分容器镜像为目的，具体为virt-api，virt-operator，virt-handler，virt-controller，virt-launcher，所以目前适配后的代码不一定能构建所有的组件和工具。

构建

在kubevirt目录下执行make go-build，cmd目录下所有编译生成的文件存放在_out目录。另外，制作镜像时需要用到csv-generator二进制，在tool/csv-generator目录下，它的编译命令为：

GOPROXY=off GOFLAGS=-mod=vendor CGO_ENABLED=0 go build
