我尝试使用带有本地ks文件的virt-install命令安装Centos 7 guest虚拟机，但卡在“已连接到域”状态 你能帮我吗 这是终端的输出：
[klaude@localhost ~]$ LANG=C sudo virt-install --connect qemu:///system \
> --name centos7-ks \
> --ram 2048 \
> --disk path=/var/lib/libvirt/images/centos7-ks.qcow2,size=10 \
> --vcpus 2 \
> --os-type linux \
> --os-variant centos7.0 \
> --network bridge=virbr0 \
> --graphics none \
