Please note that only an authorized user can add/remove and configure software on Ubuntu.Īfter you have entered the password for sudo, the system might prompt you with a y/n option to verify if you want to continue installation.

GREP VMX PROC CPUINFO INSTALL

Since most Ubuntu systems do not have this facility by default, you can install is by running the following command as sudo: $ sudo apt-get install cpu-checker The cpu-checker utility is another way to check virtualization technology, among many other things. Method 2: Through the cpu-checker utility Navigate to the Virtualization output the result VT-x here ensures that virtualization is indeed enabled on your system. Here is the output format you usually see: Simply run the following command in your Ubuntu Terminal: $ lscpu This information includes the number of processors, CPU operation mode, sockets, cores, threads, model name, and virtualization information, among much more. This command extracts hardware information from the /pro/cpuinfo file of sysfs. The lscpu command is a popular method to extract information about your CPU’s architecture. Verifying VT on your processor Method 1: Through the lscpu command You can open the Terminal application either through the system Dash or the Ctrl+Alt+T shortcut. We will be using the Ubuntu command line, the Terminal, in order to verify VT on our processor. We have run the commands and procedures mentioned in this article on a Ubuntu 18.04 LTS system. The article explains the following methods to check if Virtual Technology is supported by your processor on a Ubuntu system: Only then you can run virtual machines using a single processor. Whenever you want to install virtualization applications on your Ubuntu system such as VMware Workstation, VirtualBox etc., you should first verify if your system supports virtualization and if it is enabled. This enables several operating systems to be running on the same machine at the same time.
