使用 fdisk 实用程序管理磁盘

Question

我是 Fedora 新手，我想创建 8GB 磁盘，然后创建三个不同大小的分区。

-第一个分区为 8MB

-第二个分区有192MB

-第三个分区有7.8GB

但它显示磁盘大小只有 192KB。我知道 qcow2 映像会随着数据的插入而扩大到其最大大小。但我想创建上面提到的分区布局。请帮助我......！！

[root@localhost zzz]# qemu-img create -f qcow2 guest.qcow2 8G
Formatting 'guest.qcow2', fmt=qcow2 size=8589934592 encryption=off cluster_size=65536 lazy_refcounts=off 

[root@localhost zzz]# fdisk guest.qcow2
Welcome to fdisk (util-linux 2.25.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
