我已经安装了KVM虚拟机和虚拟管理器根据本指南：https://linuxconfig.org/install-and-set-up-kvm-on-ubuntu-18-04-bionic-beaver-linux。
在创建新虚拟机时，我可以进行相当多的操作，直到到达第 4 步（共 5 步）：
Uncaught error validating install parameters: Requested operation is not valid: storage pool 'default' is not active

答案1
存储池必须处于活动状态，然后才能使用其包含的存储。
默认情况下，指定的存储池default处于活动状态并自动启动，但它可能已在您的系统上重新配置。
您可以自行启动它virsh，例如启动池：
sudo virsh pool-start default
并将池标记为在启动时自动启动：
sudo virsh pool-autostart default
