StratoVirt

StratoVirt is an opensource VMM(Virtual Machine Manager) which aims to perform next generation virtualization.

Based on Rust programming language, StratoVirt is lightweight, efficient and safe. StratoVirt reduces memory resource consumption and improves VM startup speed while retains isolation capability and security capability of traditional virtualization.

StratoVirt supports communicating with external systems using OCI compatible Interface, and can be applied to microservices or serverless scenarios.

StratoVirt reserves interface and design for importing more features, even standard virtualization.

How to start

Preparation

Before building StratoVirt, make sure that Rust language and Cargo have already been installed. If not, you can find installation guidance from the following link:

https://www.rust-lang.org/tools/install

Build StratoVirt

To build StratoVirt, clone the project and build it first:

$ git clone https://gitee.com/openeuler/stratovirt.git
$ cd stratovirt
$ cargo build --release

Now you can find StratoVirt binary in target/release/stratovirt.

Run a VM with StratoVirt

To run StratoVirt quickly, requires

• A PE format Linux kernel
• An EXT4-format rootfs image

# If the socket of api-channel exists, remove if first.
$ ./target/release/stratovirt \
    -kernel /path/to/kernel \
    -append console=ttyS0 root=/dev/vda reboot=k panic=1 \
    -drive file=/path/to/rootfs,id=rootfs,readonly=off \
    -api-channel unix:/path/to/socket \
    -serial stdio

The detailed guidance of making rootfs, compiling kernel and building StratoVirt can be found in StratoVirt QuickStart.

StratoVirt supports much more features, the detailed guidance can be found in Configuration Guidebook.
