#UBUNTU CPUINFO PASSWORD#
The value SOME_HASHED_PASS, as the name suggests, contains the hashed password that the created user will receive. The minimum configuration necessary for a basic system installation looks like this: #cloud-config There is of course the possibility of using debian preseed (Ubuntu is a mutated Debian), however the autoinstall mentioned above will be more friendly. Now it’s time to prepare the automatic installation configuration.
We will create a 10GB file which will be our virtual disk for the machine. We will start by preparing the “place” where the system will be installed. We will create a virtual machine with Ubuntu Server 20.04, so in this case we can use the autoinstall tool. There are two ways to do this – you can do it manually using virt-manager or use an automated solution. You have successfully prepared the environment, so you can move on to setting up a virtual machine. virt-manager is a window-based virtual machine managerįinally, the user should be added to the groups kvm and libvirt: sudo usermod -aG libvirt $(whoami)įor the above commands to take effect, you must log out and log back in.virtinst contains a package of commands to manage virtual machines.bridge-utils is used to configure bridges that allow network communication.libvirt-clients allows you to manage virtualization platforms.libvirt-daemon-system adds configuration files to run the service on your system.quemu-kvm is used to support KVM hardware virtualization.
#UBUNTU CPUINFO INSTALL#
The next step to perform is to install the following packages: sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virtinst virt-manager If everything is configured correctly, when you run the kvm-ok command, you should see more or less this message: INFO: /dev/kvm exists This is done with the kvm-ok command, which becomes available after installing the package cpu-checker: sudo apt install cpu-checker The next step is to check whether the processor supports hardware virtualization.
#UBUNTU CPUINFO MANUAL#
There is no one way to do it – it’s worth checking in the manual or on the manufacturer’s website. If it returns 0, you have to check in BIOS settings if virtualization is enabled. In my case, the command returned 16, which is the number of CPU cores.
Use the following command to do this: grep -Eoc '(vmx|svm)' /proc/cpuinfo
The first step is to verify if the processor supports virtualization technology.
