# QEMU-Automator
Spawn virtual machines with pre-configured data files.
Repository for the project component of the course CSE4011 (Virtualization), maintained by [Shantanu Verma](https://github.com/SaurusXI), [Rohan Mukherjee](https://github.com/roerohan), and Bhavya Taneja.
The tools created herein are motivated by a literature survey we performed on this subject.
## Requirements
- qemu
- kvm
- cdrtools (or genisoimage)
- cloud image - [sample](https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img)
## Usage
### Step 1
Store the cloud-image in the root directory. For the purpose of simplicity, we will refer to it as `cloud.img`.
```bash
wget -O cloud.img https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img
```
### Step 2
Edit the `user-data` according to your requirements. It is in `yaml` format.
```yaml
# cloud-config
users:
- name: roerohan
gecos: Rohan Mukherjee
ssh-authorized-keys:
- ssh-rsa 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 roerohan@anarchy
sudo: ['ALL=(ALL) NOPASSWD:ALL']
groups: sudo
shell: /bin/bash
```
### Step 3
Edit the `meta-data` file, if necessary. This is also in `yaml` format.
```yaml
instance-id: id-12345
local-hostname: virt-ubuntu
```
### Step 4
Run `script.sh`. This will automatically add your SSH key and other data from `user-data` to the image.
```bash
./script.sh
```
You will now be able to SSH into the ubuntu server, with the username and private key corresponding to the entered public key.
