我在 1TB 磁盘上全新安装的 ubuntu server 18.04 上设置了 kvm。磁盘上没有其他东西。无论我使用 virt-manager 还是 virsh on cli 创建池，我总是得到一个 3.75GB 的池池大小的屏幕截图池中剩余空间这么少的原因是我有一个用于我试图创建的虚拟服务器的 ubuntu 服务器映像。
默认池的大小为 3.75GB，我创建的每个新池都以此大小创建。我试图为我的虚拟服务器创建一个 750GB 的池，但搞不清楚。我从未被提供指定池大小的选项，只有卷大小，但这受到池大小的限制。我想象 qemu 会默认将磁盘上的所有可用空间用作池。所有在线设置 kvm 虚拟服务器的示例都有比我更大的池。我错过了什么？
