当资源请求注解与系统资源不匹配时，对等 pod 会失败
io.katacontainers.config.hypervisor.default_vcpus 和 io.katacontainers.config.hypervisor.default_memory 注解的值遵循 QEMU 的语义，它有以下对对等 pod 的限制：
如果将
io.katacontainers.config.hypervisor.default_memory设置为256，则会显示以下错误：Failed to create pod sandbox: rpc error: code = Unknown desc = CreateContainer failed: Memory specified in annotation io.katacontainers.config.hypervisor.default_memory is less than minimum required 256, please specify a larger value: unknown

如果将
io.katacontainers.config.hypervisor.default_memory设置为256，将io.katacontainers.config.hypervisor.default_vcpus设置为1，则会从列表中启动最小的实例类型或实例类型。 -
如果将
io.katacontainers.config.hypervisor.default_vcpus设置为0，则所有注解都会被忽略，并启动默认实例。
临时解决方案：将 io.katacontainers.config.hypervisor.machine_type 设置为配置映射中指定的默认 AWS 实例类型或 Azure 实例大小，以启用灵活的 pod 虚拟机大小。
