@522623905 是的,这里是 qcow2 格式的镜像,能否启动还是和 bios 引导有关系的。
比如 bios 设置的是 legacy 模式的引导,就要求 qcow2 镜像是 legacy 引导的;如果 bios 设置了 uefi 引导,就要求 convert 的镜像是 uefi 的。

谢谢。
还有一些问题请教:
1)这些qcow2镜像是特殊制作的,还是一般的都可以这么支持呢?
2)那对于通用的ISO镜像是否支持呢?在这里找到个链接,意思是说上传ISO镜像时,会自动转换成qcow2格式,使得就可以支持了吗?

@522623905 这里有一些我们制作镜像的脚本,主要是依赖 pakcer 这个工具来自动化制作:https://github.com/yunionio/service-images,物理机镜像最关键的是要默认给 initramfs 里面添加 raid 和 nvme 之类的磁盘驱动:https://github.com/yunionio/service-images/blob/master/scripts/ubuntu/dracut-config.sh#L8-L23

通用的 ISO 需要虚拟机从 ISO 启动,然后装好系统后,执行保存虚拟机镜像,然后平台会自动把虚拟机的系统盘保存成 qcow2 格式的镜像文件。
