DebianInstall

Start

after following the instructions in https://wiki.ircnow.org/index.php?n=Vmm.DebianIso

we create our vm with the username and the data corresponding to those entered in /etc/vm.conf previously::

vm "username" {

        owner username
        memory 1024M
        cdrom "/home/iso/debian-11.1.0-vmm.iso"
        disk /home/username/username.qcow2
        interface { 
                locked lladdr aa:bb:cc:dd:ee:ff
                switch "switch0"
        }

}

let's create our VM:

vmctl create -s 16G diskname.qcow2

file diskname.qcow2

ls -lh diskname.qcow2

Now let's start the VM and stop it 2 times:

vmctl stop diskname

vmctl start diskname

vmctl stop -f diskname

vmctl start diskname

Now let's enter the virtual machine console:

vmctl console diskname

Press CTRL + C and the installation menu will start, we go to Advance Options -> Expert install and press TAB, a command line will come out and we write by hand in the console:

/install.amd/vmlinuz priority=low DEBIAN_FRONTEND=text initrd=/install.amd/initrd.gz --- console=ttyS0,115200

During installation it will ask you for the network configuration, do not set it in the car, but enter the data provided via the vps email to have a correct network configuration ...

I recommend installing SSH SERVER already from the minimal installation, so as not to have to enable it later

I remind users not to install graphical environments as soon as they require them, and to install the GRUB on the MBR it is not necessary to "remove the installation media"

To get the new kernel: (IMPORTANT!)

apt list | egrep 'linux-image.*bpo..-amd64-unsigned'

apt install linux-image-5.14.0-0.bpo.2-amd64-unsigned

Now enter your authorized_keys ...

To enable sudo on debian just install as root:

apt install sudo

and now let's go to give sudo permissions to our user:

adduser user sudo

Then we edit the / etc / sudoers file and add

USERNAME ALL=(ALL:ALL) ALL

now we exit as root and we try to run the sudo command by the user even for a simple update we do:

sudo apt update

it will ask you for the user's password to have permissions to run apt

sudo apt upgrade

if there are updates, it will advise you to install them for install other packages use:

apt install namepckg <------ by root

sudo apt install namepckg <------ by user

now we close the console and connect to our VPS from SSH and log in
