红帽全球峰会3.3. 检查 Overcloud 镜像
您可能旨在探索 overcloud-full.qcow2 的内容。使用 qemu-system-x86_64 命令创建虚拟机实例：
sudo qemu-system-x86_64 --kernel overcloud-full.vmlinuz --initrd overcloud-full.initrd -m 1024 --append root=/dev/sda --enable-kvm overcloud-full.qcow2
$ sudo qemu-system-x86_64 --kernel overcloud-full.vmlinuz --initrd overcloud-full.initrd -m 1024 --append root=/dev/sda --enable-kvm overcloud-full.qcow2或者在 virt-manager 中使用以下引导选项：
- 内核路径： /overcloud-full.vmlinuz
- initrd 路径： /overcloud-full.initrd
- 内核参数： root=/dev/sda
