Install VM via virt-install

On a Ubuntu 19.04
## Install the necessary package:
```
sudo apt-get install \
  qemu-kvm \
  libvirt-daemon-system \
  libvirt-clients \
  bridge-utils \
  libosinfo-bin \
  libguestfs-tools
```
## Download the ISO to:
```
/var/lib/libvirt/boot
```
Do not use a live-cd ISO. Use a proper installation ISO.

## To manipulate VMs (create/remove)
```
sudo virsh list --all
sudo destroy vm-name
sudo undefined vm-name
```
Beware, not using `sudo` will show you a different VM list.

## Install a ubuntu server installation ISO:
```
sudo virt-install --name=ubuntu-server-19.10 \
  --memory=16384 --vcpus=8 --cpu host --hvm \
  --os-variant=ubuntu19.10 \
  --location /var/lib/libvirt/boot/ubuntu-19.10-server-amd64.iso \
  --disk /var/lib/libvirt/images/ubuntu-server-19.10.img,size=10,device=disk,bus=virtio \
  --graphics none \
  --network default \
  --extra-args 'console=ttyS0' \
  --unattended profile=jeos,user-password-file=/home/jd/pass
```
Edit grub to add a console access:
```
sudo virt-edit -d ubuntu-server-19.10 /boot/grub/grub.cfg
```
And to the line
```
linux .....
```
append:
```
linux ..... console=ttyS0,115200n8 text
```
When you boot the wait a while and:
```
sudo virsh console vm-name
```
To permanently change the hostname of your machine (ubuntu)
```
sudo hostnamectl set-hostname newNameHere
```

To connect using ssh, to get the IP address of your VM:
```
virsh net-dhcp-leases default
```
Then connect as usual on port 22.

Don't forget to configure PROXY envs and `alias sudo=sudo -E`

## To forward a port:

https://wiki.libvirt.org/page/Networking#Forwarding_Incoming_Connections

This will involve [fixing your IP address to a static IP](https://aboullaite.me/kvm-qemo-forward-ports-with-iptables/).
Then [configuring a qemu hook to setup iptable forwardning](https://wiki.libvirt.org/page/Networking#Forwarding_Incoming_Connections)


## To prepare your VM for docker:
Install utils:
```
sudo apt-get install \
    curl \
    git
```

Install docker: follow https://docs.docker.com/engine/install/ubuntu/
Docker and proxy: https://docs.docker.com/config/daemon/systemd/
