2. Create a new VM:

syzqemuctl create my-vm

3. Run the VM:

syzqemuctl run my-vm --kernel /path/to/kernel

4. Check VM status:

syzqemuctl status my-vm

5. Copy files to/from VM:

syzqemuctl cp local-file my-vm:/remote/path  # Copy to VM
syzqemuctl cp my-vm:/remote/file local-path  # Copy from VM

6. Execute commands in VM:

syzqemuctl exec my-vm "uname -a"

7. Stop the VM:

syzqemuctl stop my-vm

8. List all VMs:

syzqemuctl list

⭐ As a Python package

from syzqemuctl import VM, ImageManager, VMConfig

manager = ImageManager("/path/to/images_home")
manager.initialize()
manager.create_image("my-vm")
vm = VM("/path/to/images_home/my-vm")
vm.start(kernel_path="/path/to/kernel")
# Wait several minutes for the VM to be ready
with vm:
    vm.copy_to_vm("/path/to/local/file", "/path/to/vm/remote/file")
    vm.execute("uname -a")
