 A very minimal vmm built using Linux Kernel Virtual Machine for Linux.

 

 Following project is under-development expect unfinished components.

 

 ![Image](../main/assets/wiser.png?raw=true) 

## Usage

User needs to download and build kernel images from https://www.kernel.org/.

```bash 

Usage: wiser [OPTION...] --image path-to-kernel-image

wiser - Extremely tiny type-2 hypervisor for linux. Will boot your

unikernel/linux someday.

  -c, --vcpu                 Number of cpu for your vm

  -i, --image=IMAGE          linux kernel bzImage

  -r, --memory               Ram size for your vm

  -v, --verbose              Produce verbose output

  -?, --help                 Give this help list

      --usage                Give a short usage message

  -V, --version              Print program version

Mandatory or optional arguments to long options are also mandatory or optional

* #### image

Path to linux kernel bzImage. The bzImage file is in a specific format. It contains concatenated ```bootsect.o + setup.o + misc.o + piggy.o```.

## Roadmap

* ~~Allow users to load initramfs. Closed in https://github.com/flouthoc/wiser/pull/4~~

* Add basic support for Apple hypervisor
