redhat linux (AWS) 上无法启动 kickstart 安装

Question

我想进行 centos 7 的 kickstart 安装，但是 VM 启动后却将我引导至手动文本安装（成功）。

我运行这个命令来开始安装

virt-install --name centos7 --ram 2500 --disk path=/var/lib/libvirt/images/centos7.qcow2,size=8 --vcpus 1 --os-type linux --network bridge=virbr0 --graphics none --console pty,target_type=serial --location 'http://mirror.i3d.net/pub/centos/7/os/x86_64/' --initrd-inject=anaconda-ks.cfg  --extra-args 'console=ttyS0,115200n8 serial file:./anaconda-ks.cfg'

这是我的 anaconda-ks.cfg 的内容

你能帮忙吗
