VMWare安装Gentoo错误"cannot open root device sda3..."

本文仅仅记录解决问题的过程...供大家参考

问题的原因是由于缺少SCSI驱动引起的

解决方法如下：

Step 1: 修改SCSI驱动类型

VM->Edit Settings->SCSI controller 0->change type，设为BusLogic

此项设置据说是因为2.6+的内核不再支持LSI Logic

Step 2: 用LiveCD启动，并进入编译环境

参考http://www.gentoo.org/doc/en/gentoo-x86-quickinstall.xml

livecd / # mount /dev/sda3 /mnt/gentoo 

livecd / # mount /dev/sda1 /mnt/gentoo/boot 

livecd / # mount -t proc proc /mnt/gentoo/proc 

livecd / # mount --rbind /dev /mnt/gentoo/dev 

livecd / # chroot /mnt/gentoo /bin/bash 

livecd / # env-update && source /etc/profile 

Step 3:设置内核参数

参考：http://www.gentoo-wiki.info/HOWTO_Install_Gentoo_on_VMware_ESX_server

Linux Kernel Configuration: VMware SCSI adapter

Device Drivers ---> SCSI device support ---> ** Turn off EVERYTHING under here besides what is shown below ** <*> SCSI disk support SCSI low-level drivers ---> <*> BusLogic SCSI support

livecd linux # make menuconfig 

livecd linux # time make -j2 

livecd linux # make modules_install 

livecd linux # cp arch/i386/boot/bzImage /boot/kernel 

Step 4: 重启确认问题解决
