GiantVM QEMU

GiantVM is a many-to-one virtualization framework built atop the QEMU/KVM hypervisor that consolidates multiple physical servers into a unified virtual machine Our core technical approach provides a Single System Image without requiring any modifications to the Guest OS or userspace applications.

Introduction

The main branch hosts the DSM (Distributed Shared Memory) version of GiantVM, which can be evaluated over TCP/IP.

The shared-memory branch hosts our code that utilizes shared memory as the underlying communication and memory access mechanism for GiantVM.

To boot GiantVM, a dedicated GiantVM kernel is also required.

Installation

Step 1. Obtain the GiantVM QEMU Source

Clone the GiantVM QEMU repository from GitHub:

git clone https://github.com/GiantVM/GVM-qemu.git

Step 2. Build GiantVM QEMU

The following packages are required for compilation. Install them as needed:

sudo apt install -y python3-venv python3-pip python3-setuptools
sudo apt install ninja-build
sudo apt install -y libglib2.0-dev libpixman-1-dev
sudo apt install -y librdmacm-dev
sudo apt install -y flex bison

Enter the GiantVM QEMU source directory:

cd GVM-qemu

Configure QEMU for the x86_64 system emulator with KVM and VNC support:

./configure \
    --target-list=x86_64-softmmu \
    --enable-kvm \
    --enable-vnc \
    --disable-werror

Build QEMU with parallel jobs. Replace N with the number of available CPU cores:

make -jN

After the build completes, verify that the x86_64 QEMU binary was generated:

./build/qemu-system-x86_64 --version

The expected output is QEMU emulator version 10.1.2
