在vmware 7.0下安装   VMware.ESX.虚拟机3.5,真纠结啊。

安装至少使用1G的内存,我的本就两个G,可怜啊,分给他一个G吧。

安装还挺速度,比常见的linux发行版都快(那次在G41的主板上安装linux,就5分钟,安装速度一个字快。)。一会就安装。

 

郁闷的是,启动的时候太慢了。2个小时还没有启动起来,启动到sshd,虽然快到登陆界面了,但我还是把虚拟机关了。

2个小时,我的本快烧了,内存虽然给他1G,但vmware ESX从开机到关闭,我的CPU都是100%,满满的啊。

心疼我的本啊。难道是我的cpu不知道完全虚拟机的问题,CPU使用率太高了。

突然闻到了点糊味,吓坏了。原来是后面的电热风的问题。吓吓吓啊、

 

不敢玩了,有时间用公司真实机做,不支持完全虚拟化。

linux应用--硬件信息查看

真乱---整理下、、、
1, 主板信息 .查看主板的序列号 -------------------------------------------------- #使用命令 dmidecode | grep -i 'serial number' #查看板卡信息 cat /proc/pci --------------------------------------------------

2, cpu信息 -------------------------------------------------- #通过/proc文件系统
1) cat /proc/cpuinfo #通过查看开机信息
2) dmesg | grep -i 'cpu' # 3)dmidecode -t processor --------------------------------------------------

3, 硬盘信息 -------------------------------------------------- #查看分区情况 fdisk -l #查看大小情况 df -h #查看使用情况 du -h # hdparm -I /dev/sda # dmesg | grep sda --------------------------------------------------

4, 内存信息 -------------------------------------------------- 1) cat /proc/meminfo 2) dmesg | grep mem
3) free -m
4) vmstat
5) dmidecode | grep -i mem --------------------------------------------------

5, 网卡信息 --------------------------------------------------
1) dmesg | grep -i 'eth'
2) cat /etc/sysconfig/hwconf | grep -i eth 3) lspci | grep -i 'eth' --------------------------------------------------

6, 鼠标键盘和USB信息查看键盘和鼠标:
cat /proc/bus/input/devices
查看USB设备:
cat /proc/bus/usb/devices
查看各设备的中断请求(IRQ):
cat /proc/interrupts

7, 显卡信息 --------------------------------------------------
1)lspci |grep -i 'VGA' 2)dmesg | grep -i 'VGA' --------------------------------------------------

8, 声卡信息 --------------------------------------------------
1)lspci |grep -i 'VGA' 2)dmesg | grep -i 'VGA' --------------------------------------------------

9, 其他命令 .用硬件检测程序kuduz探测新硬件:
service kudzu start ( or restart) .dmesg (查看所有启动时检测到的硬件信息) .
lspci (显示外设信息, 如usb,网卡等信息) .
cat /etc/sysconfig/hwconf .mpstat

10, 需要手动安装的工具 lshw,hwinfo,hal-device-manager

Solaris如何检测硬件参数 俺从别处发现了些有意思的东西:
Solaris的硬件相关命令
1).查看当前处理器的类型和速度(主频)
# psrinfo –v

Status of processor 1 as of: 11/24/01 10:34:41 Processor has been on-line since 11/24/01 10:18:20. The sparcv9 processor operates at 432 MHz, and has a sparcv9 floating point processor. Status of processor 3 as of: 11/24/01 10:34:41 Processor has been on-line since 11/24/01 10:18:22. The sparcv9 processor operates at 432 MHz, and has a sparcv9 floating point processor.

2).打印当前的OBP版本号
# prtconf –V

OBP 3.20.0 2000/10/24 10:47
# /usr/platform/sun4u/sbin/prtdiag –v | grep OBP

OBP 3.20.0 2000/10/24 10:47 POST 6.1.0 2000/10/24 10:49 ok. .version Release 3.20 Version 0 created 2000/10/24 10:47 OBP 3.20.0 2000/10/24 10:47 POST 6.1.0 2000/10/24 10:49 OBDIAG 4.5.1 2000/10/24 10:48

3).查看硬盘物理信息(vendor, RPM, Capacity)
# iostat –E
sd0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: SEAGATE Product: ST34371W SUN4.2G Revision: 7462 Serial No: JDX394220KW EBC Size: 4.29GB <4292075520 bytes>; Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 sd2 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: FUJITSU Product: MAJ3364M SUN36G Revision: 0804 Serial No: 01M18144 Size: 36.42GB <36418595328 bytes>; Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 sd3 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: FUJITSU Product: MAJ3364M SUN36G Revision: 0804 Serial No: 01M16199 Size: 36.42GB <36418595328 bytes>; Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 sd21 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: TOSHIBA Product: DVD-ROM SD-M1401 Revision: 1007 Serial No: 06/22/00 Size: 18446744073.71GB <-1 bytes>; Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0

4).查看磁盘的几何参数和分区信息
# prtvtoc
/dev/rdsk/c0t0d0s0 * /dev/rdsk/c0t0d0s0 partition map * * Dimensions: * 512 bytes/sector * 135 sectors/track * 16 tracks/cylinder * 2160 sectors/cylinder * 3882 cylinders * 3880 accessible cylinders * * Flags: * 1: unmountable * 10: read-only * * Unallocated space: * First Sector Last * Sector Count Sector * 8277120 103680 8380799 * * First Sector Last * Partition Tag Flags Sector Count Sector Mount Directory 0 2 00 0 2049840 2049839 / 1 3 01 2049840 615600 2665439 2 5 00 0 8380800 8380799 5 0 00 2665440 2458080 5123519 /opt 6 4 00 5123520 3073680 8197199 /usr 7 8 00 8197200 79920 8277119 /export/home

5).显示已经使用和未使用的i-node数目
# df –F ufs –o i

Filesystem iused ifree %iused Mounted on /dev/dsk/c0t0d0s0 7859 479821 2% / /dev/dsk/c0t0d0s6 37763 339517 10% /usr /dev/dsk/c0t0d0s5 722 301102 0% /opt /dev/dsk/c0t0d0s7 4 24380 0% /export/home

6).显示cpu使用率最高的进程
# ps –eo pid,pcpu,args | sort +1n

该命令输出当前系统进程的pid, CPU占用率及命令描述,并以pcpu来排序

7).显示内存占用率最高的进程
# ps –eo pid,vsz,args | sort +1n

该命令输出当前系统进程的pid,内存占用率及命令描述,并以vsz来排序

8).查看及启动系统的32位或64位内核模式 64位模式
# isalist –v

sparcv9+vis sparcv9 sparcv8plus+vis sparcv8plus sparcv8 sparcv8-fsmuld sparcv7 sparc
# isainfo –v

64-bit sparcv9 applications 32-bit sparc applications
# isainfo –b

64 启动64位内核模式 ok. boot kernel/sparcv9/unix 32位模式
# isalist –v 

sparcv8plus+vis sparcv8plus sparcv8 sparcv8-fsmuld sparcv7 sparc
# isainfo –v

32-bit sparc applications
# isainfo –b

32 启动32位模式 ok. boot kernel/unix

9).查看当前的OpenWindows版本
# showrev –w

OpenWindows version: X11 Version 6.4.1 5 November 2001

10).查看当前CDE的版本
# /usr/ccs/bin/what /usr/dt/bin/dtmail 

/usr/dt/bin/dtmail: CDE Version 1.4.6_06 CDEVersion1.4.6_06

11).测定当前的显示器刷新频率

/usr/sbin/ffbconfig –rev

Valid values for -res option are: 1024x768x60 [1] 1024x768x70 [1] 1024x768x75 [1] [2] 1024x768x77 1024x800x84 1152x900x66 1152x900x76 1280x800x76 [1] [2] 1280x1024x60 [1] [2] 1280x1024x67 1280x1024x76 1280x1024x85 [1] [2] 960x680x112s 960x680x108s 640x480x60 [1] [2] 640x480x60i [1] 768x575x50i [1] 1440x900x76 [1] [2] 1600x1000x66 [1] [2] 1600x1000x76 [1] [2] 1600x1280x76 [1] [2] 1920x1080x72 [1] [2] 1920x1080x76 [1] [2] 1920x1200x70 [1] [2] 1920x1200x75 [1] [2] svga [1] 1152 1280 stereo vga [1] [2] ntsc [1] pal [1] none Notes: [1] monitor does not support this resolution. [2] this version of FFB (FFB1) does not support this resolution

12).查看系统配置
# /usr/platform/sun4u/sbin/prtdiag –v

ps:做系统移植的时候,非常有用。网卡芯片什么的,驱动也好移植。

#!/bin/sh

#by:key1088

services=`chkconfig --list|cut -f1`
for ser in $services
do
if [ "$ser" == "network" ]||[ "$ser" == "syslog" ]||[ "$ser" == "sshd" ]||[ "$ser" == "crond" ]||[ "$ser" == "atd" ];
then
    chkconfig "$ser" on
else
    chkconfig "$ser" off
fi
done
echo "network success!"
echo "syslog sucss!!"
echo "sshd success!!!!"
echo "crond success!!"
echo "atd success!!"

e2label device [newlabel]   创建设备的标签命令
比如我们想把文件系统为ext3 的分区/dev/hda5的标签设备为 /5 ,我们应该执行如下的命令:
[root@localhost]# e2label /dev/hda5 /5

如果是reiserfs文件系统,我们应该用
[root@localhost]# reiserfstune -l 标签 设备
举例:比如我为reiserfs 文件系统 /dev/hda10设置标签为 /10 ;
[root@localhost]# reiserfstune -l /10 /dev/hda10

警告: 请不要在您的Linux的安装分区(也就是Linux系统/ 所在的分区)实践,会导致您的Linux系统崩溃;如果想实践,请在其它分区测试。

破坏的话,用光盘进入查看LABEL,或修复,进入grub修改也可以。
