+# Create host with disko-install
+How to use disko-install is described here: https://github.com/nix-community/disko/blob/master/docs/disko-install.md
+---
+Here are the exact steps to get bakunin running:  
+First create machines/hostname/configuration.nix  
+Add hosts nixosConfiguration in machines/configurations.nix  
+Boot nixos installer on the Machine.  
+``` bash
+# establish network connection
+wpa_passphrase "network" "password" > wpa.conf
+wpa_supplicant -B -i wlp3s0 -c wpa.conf
+ping 8.8.8.8
+# if that works continue
+
+# generate a base hardware config
+nixos-generate-config --root /tmp/config --no-filesystems
+
+# get the infra repo
+nix-shell -p git
+git clone https://git.dynamicdiscord.de/kalipso/infrastructure
+cd infrastructure
+
+# add the new generated hardware config (and import in hosts configuration.nix)
+cp /tmp/config/etc/nixos/hardware-configuration.nix machines/bakunin/
+
+# check which harddrive we want to install the system on
+lsblk #choose harddrive, in this case /dev/sda
+
+# run nixos-install on that harddrive
+sudo nix --extra-experimental-features flakes --extra-experimental-features nix-command run 'github:nix-community/disko/latest#disko-install' -- --flake .#bakunin --disk main /dev/sda
+
+# this failed with out of memory
+# running again showed: no disk left on device
+# it seems the usb stick i used for flashing is way to small
+# it is only 
+# with a bigger one (more than 8 gig i guess) it should work
+# instead the disko-install tool i try the old method - first partitioning using disko and then installing the system
+# for that i needed to adjust ./machines/modules/disko/btrfs-laptop.nix and set the disk to "/dev/sda"
+
+sudo nix --extra-experimental-features "flakes nix-command" run 'github:nix-community/disko/latest' -- --mode format --flake .#bakunin
+
+# failed with no space left on device.
+# problem is lots of data is written to the local /nix/store which is mounted on tmpfs in ram
+# it seems that a workaround could be modifying the bootable stick to contain a swap partition to extend tmpfs storage
+```
+
+# Testing Disko
+Testing disko partitioning is working quite well. Just run the following and check the datasets in the vm:
+```bash
+nix run -L .\#nixosConfigurations.fanny.config.system.build.vmWithDisko
+```
+
+Only problem is that encryption is not working, so it needs to be commented out. For testing host fanny the following parts in ```./machines/modules/disko/fanny.nix``` need to be commented out(for both pools!):
+```nix
+datasets = {
+  encrypted = {
+    options = {
+      encryption = "aes-256-gcm"; #THIS ONE
+      keyformat = "passphrase"; #THIS ONE
+      keylocation = "file:///tmp/root.key"; #THIS ONE
+    };
+    # use this to read the key during boot
+     postCreateHook = '' #THIS ONE 
+       zfs set keylocation="prompt" "zroot/$name"; #THIS ONE 
+     ''; #THIS ONE 
+```

+### Declaring a MicroVM
+
+The hosts nixosSystems modules should be declared using the ```makeMicroVM``` helper function.
+Use durruti as orientation:
+``` nix
+    modules = makeMicroVM "durruti" "10.0.0.5" [
+      ./durruti/configuration.nix
+    ];
+```
+
+"durruti" is the hostname.  
+"10.0.0.5" is the IP assigned to its tap interface.  
+
+### Testing MicroVMs locally
+MicroVMs can be built and run easily on your local host, but they are not persistent!
+For durruti for example this is done by:
+``` bash
+nix run .\#durruti-vm
+```
+
+### Testing persistent microvms
+In order to test persistent microvms locally we need to create them using the ```microvm``` command.  
+This is necessary to be able to mount persistent /etc and /var volumes on those hosts.  
+Do the following:
+
+```bash
+# go into our repo and start the default dev shell (or us direnv)
+nix develop .#
+
+# create a microvm on your host (on the example of durruti)
+sudo microvm -c durruti -f git+file:///home/username/path/to/infrastructure/repo
+
+# start the vm
+sudo systemctl start microvm@durruti.serivce
+
+# this may fail, if so we most probably need to create /var /etc manually, then restart
+sudo mkdir /var/lib/microvms/durruti/{var, etc}
+
+# now you can for example get the rsa host key from /var/lib/microvms/durruti/etc/ssh/
+
+# alternatively u can run the vm in interactive mode (maybe stop the microvm@durruti.service first)
+microvm -r durruti
+
+# after u made changes to the microvm update and restart the vm 
+microvm -uR durruti
+
+# deleting the vm again:
+sudo systemctl stop microvm@durruti.service
+sudo systemctl stop microvm-virtiofsd@durruti.service
+sudo rm -rf /var/lib/microvms/durruti
+```
+
+
+### Host Setup
+
+#### Network Bridge
+To provide network access to the VMs a bridge interface needs to be created on your host.
+For that:
+- Add the infrastructure flake as input to your hosts flake  
+- Add ```inputs.malobeo.nixosModules.malobeo``` to your hosts imports
+- enable the host bridge: ```services.malobeo.microvm.enableHostBridge = true;```
+
+If you want to provide Internet access to the VM it is necessary to create a nat.
+This could be done like this:
+``` nix
+networking.nat = {
+  enable = true;
+  internalInterfaces = [ "microvm" ];
+  externalInterface = "eth0"; #change to your interface name
+};
+```
+#### Auto Deploy VMs
+By default no MicroVMs will be initialized on the host - this should be done using the microvm commandline tool.
+But since we want to always deploy certain VMs it can be configured using the ```malobeo.microvm.deployHosts``` option.
+VMs configured using this option will be initialized and autostarted at boot.
+Updating still needs to be done imperative, or by enabling autoupdates.nix
+
+The following example would init and autostart durruti and gitea:
+``` nix
+malobeo.microvm.deployHosts = [ "durruti" "gitea" ];
+```

+    - Get public key using `$ age-keygen -y ~/.config/sops/age/keys.txt`
+    - Write public key in `.sops.yaml` under `keys:` in the format `- &admin_$USER $PUBKEY`
+
+- Write `- *admin_$USER` under the apropriate `key_grups:` of the secrets the user should have access to
