CentOS 7 主机需要使用virt-install
和安装 CentOS 7 来宾kickstart
,但下面记录的方法无法识别指定的硬盘驱动器或依赖项。
为了让安装过程能够识别硬盘和依赖项,需要对以下内容进行哪些具体更改?
错误症状:
以下是 Putty 在来宾操作系统安装过程中打印出的内容:

磁盘是如何创建的:
使用以下两个命令在主机上创建磁盘映像:
cd /home
qemu-img create -f qcow2 disk_test.img 100G

命令
virt-install
:触发生成上述输出的安装过程的命令virt-install
如下:
[root@remote-host ~]# virt-install --name=public-centos7 --disk path=/home/disk_test.img,size=99 --graphics none --vcpus=1 --memory=2048 --location /tmp/CentOS-7-x86_64-Minimal-1611.iso --network bridge=virbr0 --os-type=linux --os-variant=rhel7.0 --initrd-inject=/tmp/vm.ks --extra-args "ks=file:/vm.ks console=ttyS0"
尝试查看日志:
我尝试挂载来宾的磁盘映像以查看日志,但收到以下消息,表明磁盘文件系统似乎为空:

[root@remote-host ~]#
验证磁盘映像:
根据 @garethTheRed 的建议,我输入了以下内容:
[root@remote-host ~]# virt-filesystems -a /home/disk_test.img
[root@remote-host ~]#
针对该命令没有结果,具体应该做哪些改变? 是否需要添加分区disk_test.img
?如果是这样,怎么办?
作为参考,以下是物理驱动器的内容:

[root@remote-host ~]#
请注意位于/home/disk_test.img
分区中/dev/mapper/centos-home
,即主机的分区。我只是把它放在那里,让初学者在改进之前简单地得到一些东西。
另外供参考,可用的存储池如下:
[root@remote-host ~]# virsh pool-list
Name State Autostart
-------------------------------------------
home active yes
root active yes
anotherUserName active yes
tmp active yes
[root@remote-host ~]#
我是否应该为其他分区之一创建一个存储池,然后在其中创建一个存储卷,并将其中一个或另一个传递到命令中virt-install
?
