VMWare安裝Gentoo錯誤“cannot open root device sda3...”

解決方法如下：

Step 1: 修改SCSI驅動類型

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

此項設置據說是因為2.6+的內核不再支持LSI Logic

Step 2: 用LiveCD啟動，並進入編譯環境

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

1. livecd / # mount /dev/sda3 /mnt/gentoo  
2. livecd / # mount /dev/sda1 /mnt/gentoo/boot  
3. livecd / # mount -t proc proc /mnt/gentoo/proc  
4. livecd / # mount --rbind /dev /mnt/gentoo/dev  
5. livecd / # chroot /mnt/gentoo /bin/bash  
6. livecd / # env-update && source /etc/profile  

Step 3:設置內核參數

參考：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

1. livecd linux # make menuconfig  
2. livecd linux # time make -j2  
3. livecd linux # make modules_install  
4. livecd linux # cp arch/i386/boot/bzImage /boot/kernel  

Step 4: 重啟確認問題解決
