There is a problem with installing linux in a virtual machine People who know help me

When creating or adding a hard disk for a virtual machine, select the IDE type, if you select SCSI, some older versions of Linux, such as Red Hat 9, will not recognize the hard disk.

What's the problem? What virtual machines are used.

How to install 64-bit Linux in VMware:

1. The CPU of the CPU AMD series is skipped.

Intel series CPU chips need to support EM64T and VT technology, and the BIOS must also support it.

2、bios

Set the BIOS to Virtualization Technology to Enabled and save.

After saving the modified BIOS, you need to cold start it, that is, turn it off and start it again. This setting will only take effect, otherwise it will not work.

3. Load the ubuntu installation medium and start the installation smoothly.

When the installation is 72%, it will stop at the "configuring apt" and "scanning the mirror" places, at this time, you can set the network connection mode of VMware to host-only, so that you can disconnect from the Internet, do not get information, and the installation will be completed smoothly.

4. Install vwmare tools

Due to security considerations, Ubuntu prohibits root users by default, and your current user will not be able to install VMware Tools. You can first set the root password by using 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 show all the information, and if you see 64 in it, it means 64 bits, and if you don't, it is 32 bits.

The reasons may be as follows:

1. The machine is 32-bit.

2. The system is 32-bit.

3. CPU virtualization is not enabled in the motherboard settings.

Notebook Toshiba M332 operating system: Windows Vista HomeCPU Model: Intel Core 2 Duo T6400

software virtualization is incompatible with long mode on this platform. disabling long mode. without long mode support, the virtual machine will not be able to run 64 bit code.

Is it because the memory of your physical machine is not large enough to support it?
