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

 参考：http://www.linuxso.com/linuxrumen/14856.html

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

建议直接编辑虚拟主机目录下的gentoo.vmx文件  scsi0.virtualDev = "buslogic"   （原先为lsilogic）

 

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/gentoolivecd / # mount /dev/sda1 /mnt/gentoo/bootlivecd / # mount -t proc proc /mnt/gentoo/proclivecd / # mount --rbind /dev /mnt/gentoo/devlivecd / # chroot /mnt/gentoo /bin/bashlivecd / # 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 devicesupport  ---> ** Turn off EVERYTHING under here besides what is shown below **     <*> SCSI disk support         SCSI low-level drivers  --->            <*> BusLogic SCSI support

Step 4: 重启确认问题解决

livecd conf.d #exit
livecd / #umount /mnt/gentoo/dev /mnt/gentoo/proc /mnt/gentoo/boot /mnt/gentoo
livecd / #reboot
