1. CPU Of The CPUAMD series is omitted from the CPU chips of the Intel series. EM64T and VT technologies must be supported, and BIOS must be supported. To determine whether your IntelCPU supports VT, check here. My notebook DELL630CPU is: IntelMobileCore2DuoT7100 supports EM64T. If you do not set support for VT in the BIOS

1. CPU
AMD series CPU skipped
Intel series CPU chips must support EM64T and VT technologies, and BIOS must support them.
To determine whether your Intel CPU supports VT, check here.
My notebook DELL630 CPU is: Intel Mobile Core 2 Duo T7100 supports EM64T, such

If the BIOS does not support VT (Virtualization Technology), the following error will be reported after you create VMWare and install 64-bit Linux:
This CPU does not support VT.
You have configured this virtual machine to use a 64-bit guest operating system. however, this host's CPU is not capable of running 64-bit virtual machines or this virtual machine has 64-bit support disabled.
For more detailed information, see http://www.vmware.com/info? Id = 152

If it cannot be started, the following error will be reported:
This kernel requires an x86-64 CPU, but only detected an i686 CPU.
Unable to boot-please use a kernel appropriate for your CPU.
For more information about VMWare hardware requirements, see:

2. BIOS
Set BIOS, and save the settings after the Virtualization Technology is enabled.
After the modified BIOS is saved, you need to start it cold, that is, shut down and then start the system. In this way, this setting will take effect, otherwise it will still fail to take effect. Note that Windows cannot be restarted directly. Cold rebooting the machine.
Details:
Go to BIOS settings for my DELL and F2
BIOS Setup Utility
Intel (R) Virtualization Technology ==> set to Enabled
When enabled, a VMM can utilize the additional hardwar capabilities provided by Intel (R) Virtualization Technology.
NOTE
========
After any change in this option, system must be powered off to take effect.

3. Load the Ubuntu installation media and start the installation smoothly.
When it is installed in 72%, it will stop at the "rolling ing apt" and "Scanning the mirror" location. In this case, you can set the network connection mode of VMWare to Host-only, because I set it to the Bridged method at the beginning, it is also stuck here

In this way, you can disconnect the connection to the Internet without obtaining information, and the installation will be completed smoothly. Of course, when creating a virtual machine, your network configuration is Host-only, or your Host is not connected to the network, it will be installed smoothly.

4. Install VWMare Tools
Based on security considerations, Ubuntu prohibits root users by default, and your current user cannot install VMWare Tools.
You can first set the root password through sudo passwd root, then switch to the root user, and then install VMWare Tools.

5. Verification
Check whether the Linux system is 64-bit?
Uname-m
X86_64 is displayed.
Of course, uname-a will display all the information. If _ 64 indicates that it is 64-bit, if not, it is 32-bit.
File/sbin/init
/Sbin/init: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), for GNU/Linux 2.6.8, dynamically linked (uses shared libs), stripped
However, getconf WORD_BIT is still 32, which is strange.

6. Install Sun 64-bit JDK 1.6.0.11
Java SE Development Kit (JDK) 6 Update 11 for Linux x64, Multi-language
Http://java.sun.com/javase/downloads? Intcmp = 1, 1281
./Java-version
Java version "1.6.0 _ 11"
Java (TM) SE Runtime Environment (build 1.6.0 _ 11-b03)
Java HotSpot (TM) 64-Bit Server VM (build 11.0-f8, mixed mode)
I tried to increase the memory. Note that I opened 3 GB memory for VMWare to make it so large.
./Java-Xms4577m-Xmx5099m-version
Java version "1.6.0 _ 11"
Java (TM) SE Runtime Environment (build 1.6.0 _ 11-b03)
Java HotSpot (TM) 64-Bit Server VM (build 11.0-f8, mixed mode)

7. Load shared folders on Windows machines
Switch to the root user first, and then mount it as follows
Mount-t smbfs-o codepage = cp936, username = Windows Shared username, password = password-l // ip address/Shared Folder name mount point in Linux

8. Summary

Technical support for CPU EM64T and VT;
It is important that the bios vt switch must be set to take effect after the cold start. Otherwise, it will not work;
Do not connect to the network during installation. After installation, connect to the network to install other software;
To install VMWare Tools and load Windows shared folders, you must switch to the root user.

After installation, how can I check whether LINUX is 64bit or 32bit?

1. # uname-mx86_133. # archx86_64
