VM选择内核

来源：互联网发布：淘宝上有真翡翠吗编辑：程序博客网时间：2024/06/04 18:44

在安装完成内核后，我没发现内核选择的界面就直接进入系统了。

问了高手后才知道是这样的：

VM有这个一个问题，界面过得太快，让你感觉不到，但可以设置一下延时。

具体设置如下：

[root@localhost maokx]# more /boot/grub/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/sda2
#          initrd /initrd-[generic-]version.img
#boot=/dev/sda
