+# Hosts
+These hosts are VMs used for running the integration tests on your local machine.
+The hosts contain a client where abra with the tests will be run and a server
+to simulate a remote machine.
+
+## Prepare the host
+For this setup to work you need a machine with NixOS and flakes enabled.
+
+1. Import the abra flake
+
+The install example is based on the [using nix flakes wiki page](https://nixos.wiki/wiki/flakes#Using_nix_flakes_with_NixOS).
+```nix
+inputs = {
+  abra = {
+    url = "git+https://git.coopcloud.tech/toolshed/abra.git";
+  };
+};
+```
+2. Add the host module to your configuration
+
+Now add the host module to your configuration. At the toplevel of a flake it could look like this:
+```nix
+desktop = inputs.nixpkgs.lib.nixosSystem {
+  system = "x86_64-linux";
+  modules = [
+    abra.nixosModules.host
+    ./configuration.nix
+  ];
+  specialArgs = inputs;
+};
+```
+3. Adjust the required config
+```nix
+abra.testing = {
+  enable = true; # loads the required config, when set true
+  externalInterface = "eth1"; # adjust this to your network interface that has access to the internet
+};
+```
+You can look up the interface with `ip link`. After that rebuild your system and you are ready to go.
+
+## Get started
+All commands are run on the repository root path.
+1. Set path to repo 
+
+The VM will create a shared volume from the content of the file `tests/resources/path_to_repo`.
+Set the content of the file to the path of your abra repository and run the following command to prevent tracking of the file:
+```sh
+git update-index --assume-unchanged ./tests/resources/path_to_repo
+```
+This will share the repository from your machine with the VM and you can edit files while testing without rebuiling
+or restarting the VM.
+
+2. Create the VMs
+```sh
+make vm-client-create
+make vm-server-create
+```
+3. Start the VMs
+```sh
+make vm-client-start
+make vm-server-start
+```
+After running that command you should be able to ping the machines.
+The client runs on 10.0.0.2 and server 10.0.0.3
+
+4. Connect to the client
+
+Running the following command will connect to the client VM via SSH.
+```sh
+make vm-client-connect
+```
+5. Run the tests
+```sh
+make test-integration
+```

 There are two different approaches spew allows for dumping Go data structures:

-  - Dump style which prints with newlines, customizable indentation,
-    and additional debug information such as types and all pointer addresses
-    used to indirect to the final value
-  - A custom Formatter interface that integrates cleanly with the standard fmt

 This section demonstrates how to quickly get started with spew.  See the
 sections below for further details on formatting and configuration options.

 To dump a variable with full newlines, indentation, type, and pointer
 information use Dump, Fdump, or Sdump:
-
 	spew.Dump(myVar1, myVar2, ...)
 	spew.Fdump(someWriter, myVar1, myVar2, ...)
 	str := spew.Sdump(myVar1, myVar2, ...)

 printing style, use the convenience wrappers Printf, Fprintf, etc with
 %v (most compact), %+v (adds pointer addresses), %#v (adds types), or

-
 	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)

+# cpuid
+Package cpuid provides information about the CPU running the current program.
+
+CPU features are detected on startup, and kept for fast access through the life of the application.
+Currently x86 / x64 (AMD64/i386) and ARM (ARM64) is supported, and no external C (cgo) code is used, which should make the library very easy to use.
+
+You can access the CPU information by accessing the shared CPU variable of the cpuid library.

+
+# usage
+
+The `cpuid.CPU` provides access to CPU features. Use `cpuid.CPU.Supports()` to check for CPU features.
+A faster `cpuid.CPU.Has()` is provided which will usually be inlined by the gc compiler.  
+
+To test a larger number of features, they can be combined using `f := CombineFeatures(CMOV, CMPXCHG8, X87, FXSR, MMX, SYSCALL, SSE, SSE2)`, etc.
+This can be using with `cpuid.CPU.HasAll(f)` to quickly test if all features are supported.
+
+Note that for some cpu/os combinations some features will not be detected.
+`amd64` has rather good support and should work reliably on all platforms.
+
+Note that hypervisors may not pass through all CPU features through to the guest OS,
+so even if your host supports a feature it may not be visible on guests.
+
+## arm64 feature detection
+
+Not all operating systems provide ARM features directly 
+and there is no safe way to do so for the rest.
+
+Currently `arm64/linux` and `arm64/freebsd` should be quite reliable. 
+`arm64/darwin` adds features expected from the M1 processor, but a lot remains undetected.
+
+A `DetectARM()` can be used if you are able to control your deployment,
+it will detect CPU features, but may crash if the OS doesn't intercept the calls.
+A `-cpu.arm` flag for detecting unsafe ARM features can be added. See below.
+ 
+Note that currently only features are detected on ARM, 
+no additional information is currently available. 
+
+## flags
+
+It is possible to add flags that affects cpu detection.
+
+For this the `Flags()` command is provided.
+
+This must be called *before* `flag.Parse()` AND after the flags have been parsed `Detect()` must be called.
+
+This means that any detection used in `init()` functions will not contain these flags.
+
+Example:
+
+```Go
+package main
+
+import (
+	"flag"
+	"fmt"
+	"strings"
+
+	"github.com/klauspost/cpuid/v2"
+)
+
+func main() {
+	cpuid.Flags()
+	flag.Parse()
+	cpuid.Detect()
+
+	// Test if we have these specific features:
+	if cpuid.CPU.Supports(cpuid.SSE, cpuid.SSE2) {
+		fmt.Println("We have Streaming SIMD 2 Extensions")
+	}
+}
