StratoVirt

StratoVirt is an enterprise-level virtualization platform for cloud data centers in the computing industry. It implements a set of architecture that supports three scenarios: virtual machines, containers, and serverless computing.

StratoVirt has competitive advantages in light weight and low noise, software and hardware coordination, and Rust language-level security.

StratoVirt reserves interface and design for importing more features, even evaluates to 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 via following link:

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

And it will get smaller memory overhead if you prepare musl toolchain for rust.

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 or bzImage (only x86_64) format Linux kernel
  • An EXT4 filesystem, raw format rootfs disk image

You can get kernel and rootfs image from the following link:

https://repo.openeuler.org/openEuler-21.03/stratovirt_img/

For standard_vm, firmware file of EDK2 which follows UEFI is required.

# If the socket of qmp exists, remove it first.

# Start microvm
$ ./target/release/stratovirt \
    -machine microvm \
    -kernel /path/to/kernel \
    -append "console=ttyS0 root=/dev/vda reboot=k panic=1" \
    -drive file=/path/to/rootfs,id=rootfs,readonly=off \
    -device virtio-blk-device,drive=rootfs \
    -qmp unix:/path/to/socket,server,nowait \
    -serial stdio

# Start standard_vm
$ ./target/release/stratovirt \
    -machine standard_vm \
    -kernel /path/to/kernel \
    -append "console=ttys0 root=/dev/vda reboot=k panic=1" \
    -drive file=/path/to/firmware,if=pflash,unit=0,readonly=true \
    -device pcie-root-port,port=0x0,addr=0x1.0x0,bus=pcie.0,id=pcie.1 \
    -drive file=/path/to/rootfs,id=rootfs,readonly=off \
    -device virtio-blk-pci,drive=rootfs,bus=pcie.1,addr=0x0.0x0 \
    -qmp unix:/path/to/socket,server,nowait \
    -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.
