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：
镜像制作
参考：https://github.com/Loongson-Cloud-Community/dockerfiles/tree/main/kubevirt
其中在制作virt-launcher镜像时依赖到了libvirt rpm包，具体查看方法如下：
cmd/virt-launcher/BUILD.bazel(用来制作镜像):
container_image(
name = "version-container",
directory = "/",
files = ["//:get-version"],
tars = select({
"@io_bazel_rules_go//go/platform:linux_arm64": [
":libvirt-config",
":passwd-tar",
":nsswitch-tar",
":qemu-kvm-modules-dir-tar",
"//rpm:launcherbase_aarch64", # 指定依赖到了rpm中launcherbase_aarch64,在rpm/BUILD.bazel文件中有定义
],
.......
}),
)
container_image(
name = "virt-launcher-image",
architecture = select({
"@io_bazel_rules_go//go/platform:linux_arm64": "arm64",
"//conditions:default": "amd64",
}),
base = ":version-container",
entrypoint = ["/usr/bin/virt-launcher"],
tars = [":setcaps"],
visibility = ["//visibility:public"],
)
rpm/BUILD.bazel：
rpmtree(
name = "launcherbase_aarch64",
capabilities = {
"/usr/libexec/qemu-kvm": [
"cap_net_bind_service",
],
},
