如何在 KVM 下安装 Fedora 28 文本控制台以不提示文本模式与 VNC

一段时间以来，我一直试图让无人值守的 linux 安装（在这种情况下为 fedora 28）在 KVM 下工作。我已经解决了大部分问题，但它仍然询问我是否要使用文本模式或启动 VNC。这是一个片段来说明：

我将其用作我的 virt-install 行：

virt-install  \
--name fedoratest2 \
--ram 2048 \
--disk path=/vm-images/fedoratest2.qcow2,size=15 \
--vcpus 2 \
--network bridge=br0 \
--mac=<insert unicast mac here> \
--graphics none \
--location https://mirror.chpc.utah.edu/pub/fedora/linux/releases/28/Server/x86_64/os/ \
--os-type linux \
--extra-args "console=ttyS0 inst.ks=http://http.mydomain.com/kickstart_fedora_testing.cfg hostname=fedoratest2.mydomain.com" 

（mydomain.com 当然不是我的真实域名）

以及以下内容的启动：

#ptform=x86, AMD64, or Intel EM64T
#version=DEVEL
# Keyboard layouts
keyboard 'us'
# Root password
rootpw --plaintext thisisnotmyrootpassword
# user is needed for fedora? --disabled isn't an option
user --name="joe" --password="thisisnotmyuserpassword"

# System language

# System timezone

# Disk partitioning information

# these are what were produced in anaconda_ks.cfg after I selected what I wanted during a non-kickstart install
%packages
@^server-product-environment
@headless-management
%end

# this was in default anaconda_ks.cfg file after non-kickstart install, figure I'll keep it just in case
%addon com_redhat_kdump --disable --reserve-mb='128'

%end

让我烦恼的是启动/设置期间出现的行：

15:12:21 X startup failed, falling back to text mode
15:12:21 X startup failed, falling back to text mode

我想知道 - 为什么它甚至试图首先启动 X？我认识到我--extra-args上面的引导参数没有指定是否应该使用文本模式，据我了解，fedora/anaconda 希望默认为图形安装模式。没关系。我也使用了以下两个参数--extra-args来尝试强制它进入文本模式而不问我任何东西：

inst.text
inst.cmdline

但这些似乎都没有任何效果。它仍然抱怨，X startup failed然后问我是否要使用 VNC 或文本模式...

我正在根据官方 f28 安装指南尝试这些设置：https ://docs.fedoraproject.org/en-US/fedora/f28/install-guide/advanced/Boot_Options/

此外，这里的 anaconda 文档：https ://anaconda-installer.readthedocs.io/en/latest/boot-options.html

这console=意味着inst.txt......我很困惑。

概括：

无论我尝试指定只安装文本或 cmdline（无图形），安装程序仍会尝试运行图形，惨遭失败，并提示我指定 VNC 或文本模式。我试图找出我做错了什么，或者是否有可能让它在安装过程中不提示我做任何事情，而只是摆脱 kickstart 文件。
