 # VirtWEB
 WIP project
 
-## Development requirements
-1. The `libvirt-dev` package must be installed:
-
-```bash
-sudo apt install libvirt-dev
-```
-
-2. Libvirt must also be installed:
-```bash
-sudo apt install qemu-kvm libvirt-daemon-system
-```
-
-3. Allow the current user to manage VMs:
-```
-sudo adduser $USER libvirt
-sudo adduser $USER kvm 
-```
-
-> Note: You will need to login again for this change to take effect.
-
+## Setup for dev
+Please refer to this guide: [virtweb_docs/SETUP_DEV.md](virtweb_docs/SETUP_DEV.md)
 
 ## Production requirements
-### TODO
-TODO
-
-### Manual port forwarding without a LibVirt HOOK
-* Allow ip forwarding in the kernel: edit `/etc/sysctl.conf` and uncomment the following line:
-
-```
-net.ipv4.ip_forward=1
-```
-
-* To reload `sysctl` without reboot:
-
-```
-sudo sysctl -p /etc/sysctl.conf
-```
-
-* Create the following IPTables rules:
-
-```
-UP_DEV=$(ip a | grep "192.168.1." -B 2 | head -n 1 | cut -d ':' -f 2 |
- tr -d ' ')
-LOCAL_DEV=$(ip a | grep "192.168.25." -B 2 | head -n 1 | cut -d ':' -f 2 | tr -d ' ')
-echo "$UP_DEV -> $LOCAL_DEV"
-
-GUEST_IP=192.168.25.189
-HOST_PORT=8085
-GUEST_PORT=8085
-
-# connections from outside
-sudo iptables -I FORWARD -o $LOCAL_DEV -d  $GUEST_IP -j ACCEPT
-sudo iptables -t nat -I PREROUTING -p tcp --dport $HOST_PORT -j DNAT --to $GUEST_IP:$GUEST_PORT
-```
-
-* Theses rules can be persisted using `iptables-save` then, or using a libvirt hook.

-### Manual port forwarding with a LibVirt HOOK
-* Allow ip forwarding in the kernel: edit `/etc/sysctl.conf` and uncomment the following line:
-
-```
-net.ipv4.ip_forward=1
-```
-
-* To reload `sysctl` without reboot:
-
-```
-sudo sysctl -p /etc/sysctl.conf
-```
-
-* Get the following information, using the web ui or `virsh`:
-	* The name of the target guest
-	* The IP and port of the guest who will receive the connection
-	* The port of the host that will be forwarded to the guest
-
-* Stop the guest if its running, either using `virsh` or from the web ui
-
-* Create or append the following content to the file `/etc/libvirt/hooks/qemu`:
-
-```bash
-#!/bin/bash
-
-# IMPORTANT: Change the "VM NAME" string to match your actual VM Name.
-# In order to create rules to other VMs, just duplicate the below block and configure
-# it accordingly.
-if [ "${1}" = "VM NAME" ]; then
-
- # Update the following variables to fit your setup
- GUEST_IP=
- GUEST_PORT=
- HOST_PORT=
-
- if [ "${2}" = "stopped" ] || [ "${2}" = "reconnect" ]; then
-  /sbin/iptables -D FORWARD -o virbr0 -p tcp -d $GUEST_IP --dport $GUEST_PORT -j ACCEPT
-  /sbin/iptables -t nat -D PREROUTING -p tcp --dport $HOST_PORT -j DNAT --to $GUEST_IP:$GUEST_PORT
- fi
- if [ "${2}" = "start" ] || [ "${2}" = "reconnect" ]; then
-  /sbin/iptables -I FORWARD -o virbr0 -p tcp -d $GUEST_IP --dport $GUEST_PORT -j ACCEPT
-  /sbin/iptables -t nat -I PREROUTING -p tcp --dport $HOST_PORT -j DNAT --to $GUEST_IP:$GUEST_PORT
- fi
-fi
-```
-
-* Make the hook executable:
-
-```bash
-sudo chmod +x /etc/libvirt/hooks/qemu
-```
-
-* Restart the `libvirtd` service:
-
-```bash
-sudo systemctl restart libvirtd.service
-```
-
-* Start the guest

+# Setup for prod
+
+## Build VirtWeb for production
+Open a terminal in the root directory of the VirtWeb project, and run the following command:
+
+```bash
+make
+```
+
+The release file will be available in `virtweb_backend/target/release/virtweb_backend`. 
+
+This is the only artifcat that must be copied to the server. It is recommended to copy it to the `/usr/local/bin` directory.
+
+## Install requirements
+In order to work properly, VirtWeb relies on `libvirt`, `qemu` and `kvm`:
+
+```bash
+sudo apt install qemu-kvm libvirt-daemon-system libvirt0 libvirt-clients libvirt-daemon bridge-utils
+```
+
+## Dedicated user
+It is recommended to have a dedicated non-root user to run LibVirt:
+
+```bash
+sudo adduser --disabled-login virtweb
+sudo adduser virtweb libvirt
+sudo adduser virtweb kvm
+```
+
+When executing this command as this user, it is possible to use the following command:;
+
+```bash
+sudo -u virtweb bash
+```
+
+## Create Virtweb configuration & storage directory
+Inside the newly created user, create an environment file that will contain the configuration of the VirtWeb software:
+
+```bash
+sudo touch /home/virtweb/virtweb-env
+sudo chmod 600 /home/virtweb/virtweb-env
+sudo chown virtweb:virtweb /home/virtweb/virtweb-env
+
+sudo mkdir /home/virtweb/storage
+sudo chown virtweb:kvm /home/virtweb/storage
+
+# Fix storage access permission issue
+sudo chmod a+rx /home/virtweb
+```
+
+Edit the configuration content:
+
+```conf
+LISTEN_ADDRESS=0.0.0.0:8000
+WEBSITE_ORIGIN=http://localhost:8000
+SECRET=<rand>
+AUTH_USERNAME=user
+AUTH_PASSWORD=changeme
+DISABLE_OIDC=true
+STORAGE=/home/virtweb/storage
+HYPERVISOR_URI=qemu:///system
+```
+
+> Note: `HYPERVISOR_URI=qemu:///system` is used to sepcify that we want to use the main hypervisor.
+
+## Register Virtweb service
+Before registering service, check that the configuration works correctly:
+
+```bash
+sudo -u virtweb virtweb_backend -c /home/virtweb/virtweb-env
+```
+
+Create now a service in the file `/etc/systemd/system/virtweb.service`:
+
+```conf
+[Unit]
+Description=VirtWeb
+After=syslog.target
+After=network.target
+
+[Service]
+RestartSec=2s
+Type=simple
+User=virtweb
+Group=virtweb
+WorkingDirectory=/home/virtweb
+ExecStart=/usr/local/bin/virtweb_backend -c /home/virtweb/virtweb-env
+Restart=always
+Environment=USER=virtweb 
+HOME=/home/virtweb
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Enable and start the created service:
+
+```bash
+sudo systemctl enable virtweb
+sudo systemctl start virtweb
+```
+
+You should now be able to create VMs!
+
+### Manual port forwarding without a LibVirt HOOK
+* Allow ip forwarding in the kernel: edit `/etc/sysctl.conf` and uncomment the following line:
+
+```
+net.ipv4.ip_forward=1
+```
+
+* To reload `sysctl` without reboot:
+
+```
+sudo sysctl -p /etc/sysctl.conf
+```
+
+* Create the following IPTables rules:
+
+```
+UP_DEV=$(ip a | grep "192.168.1." -B 2 | head -n 1 | cut -d ':' -f 2 |
+ tr -d ' ')
+LOCAL_DEV=$(ip a | grep "192.168.25." -B 2 | head -n 1 | cut -d ':' -f 2 | tr -d ' ')
+echo "$UP_DEV -> $LOCAL_DEV"
+
+GUEST_IP=192.168.25.189
+HOST_PORT=8085
+GUEST_PORT=8085
+
+# connections from outside
+sudo iptables -I FORWARD -o $LOCAL_DEV -d  $GUEST_IP -j ACCEPT
+sudo iptables -t nat -I PREROUTING -p tcp --dport $HOST_PORT -j DNAT --to $GUEST_IP:$GUEST_PORT
+```
+
+* Theses rules can be persisted using `iptables-save` then, or using a libvirt hook.
+
+
+### Manual port forwarding with a LibVirt HOOK
+* Allow ip forwarding in the kernel: edit `/etc/sysctl.conf` and uncomment the following line:
+
+```
+net.ipv4.ip_forward=1
+```
+
+* To reload `sysctl` without reboot:
+
+```
+sudo sysctl -p /etc/sysctl.conf
+```
+
+* Get the following information, using the web ui or `virsh`:
+	* The name of the target guest
+	* The IP and port of the guest who will receive the connection
+	* The port of the host that will be forwarded to the guest
+
+* Stop the guest if its running, either using `virsh` or from the web ui
+
+* Create or append the following content to the file `/etc/libvirt/hooks/qemu`:
+
+```bash
+#!/bin/bash
+
+# IMPORTANT: Change the "VM NAME" string to match your actual VM Name.
+# In order to create rules to other VMs, just duplicate the below block and configure
+# it accordingly.
+if [ "${1}" = "VM NAME" ]; then
+
+ # Update the following variables to fit your setup
+ GUEST_IP=
+ GUEST_PORT=
+ HOST_PORT=
+
+ if [ "${2}" = "stopped" ] || [ "${2}" = "reconnect" ]; then
+  /sbin/iptables -D FORWARD -o virbr0 -p tcp -d $GUEST_IP --dport $GUEST_PORT -j ACCEPT
+  /sbin/iptables -t nat -D PREROUTING -p tcp --dport $HOST_PORT -j DNAT --to $GUEST_IP:$GUEST_PORT

+  /sbin/iptables -t nat -I PREROUTING -p tcp --dport $HOST_PORT -j DNAT --to $GUEST_IP:$GUEST_PORT
+ fi
+fi
+```
+
+* Make the hook executable:
+
+```bash
+sudo chmod +x /etc/libvirt/hooks/qemu
+```
+
+* Restart the `libvirtd` service:
+
+```bash
+sudo systemctl restart libvirtd.service
+```
+
+* Start the guest
