Virt-Manager错误

Question

我已经根据本指南安装了QEMU和Virt：https://linuxconfig.org/install-and-set-up-kvm-on-ubuntu-18-04-bionic-beaver-linux。

在创建新VM时，我可以走得很远，直到达到第5步中的第4步为止：

Uncaught error validating install parameters: Requested operation is not valid: storage pool 'default' is not active
Traceback (most recent call last):

存储池必须处于活动状态，才能使用它所包含的存储。

默认情况下，名为default的存储池是活动的和自动启动的，但是它可能已经在您的系统上重新配置了。

您可以自己使用virsh启动它，例如，启动池：

sudo virsh pool-start default

并在启动时将池标记为自动启动：

sudo virsh pool-autostart default
