在目前最新的linux内核中，没有8204elp的raid驱动，以至于在使用光盘安装时，找不到硬盘。

所以必须在安装时候，另外使用u盘等加载raid卡驱动

安装以后的配置相关文件

[root@asher etc]# cat modprobe.conf

alias eth0 igb

alias eth1 igb

alias scsi_hostadapter ahci

alias scsi_hostadapter1 usb-storage

alias scsi_hostadapter2 megasr

alias scsi_hostadapter3 megaraid_sas

在编译内核是出现

make[2]: warning: Clock skew detected. Your build may be

incomplete.

使用下面解决办法：

1. Are you building over an NFS volume?

2. you could do

find . -type f | xargs -n 5 touch

make clean

make

I set up my Xen config with tap:aio storage. My disk line in my

guest config is:

disk = [ 'tap:aio:/var/lib/xen/rhel5guest1.img,xvda1,w',

'tap:aio:/var/lib/xen/rhel5guest1.swap,xvda2,w' ]

Both xvda1 and xvda2 files were set up following xen.og

documentation. Attempting to boot my first guest failed on

"switchroot:mount failed". Reading more documentation and Web

posts, it looked like the error was in my initrd file. I built 3

different initrd's, excluding different combination of modules.

Here are my results for each different one:

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

# Kernel image file.

kernel = "/boot/vmlinuz-2.6.18-53.1.19.el5xen"

# Optional ramdisk.

ramdisk = "/boot/initrd-2.6.18-53.1.19.el5xen.img"
