cloud hypervisor

MicroVM：要启动基于 MicroVM 的沙盒，必须在主机上安装虚拟机管理程序。

基于 cloud hypervisor 做验证, 安装文档:

https://github.com/cloud-hypervisor/cloud-hypervisor/blob/main/docs/building.md

准备工作:

mkdir -p $HOME/work/soft/cloudhypervisor

export CLOUDH=$HOME/work/soft/cloudhypervisor

cd $CLOUDH

安装依赖包:

sudo apt-get update
sudo apt install git build-essential m4 bison flex uuid-dev qemu-utils musl-tools

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

rustup target add x86_64-unknown-linux-musl

clone 代码并开始构建:

mkdir -p ~/work/code/cloud-hypervisor
cd ~/work/code/cloud-hypervisor

git clone https://github.com/cloud-hypervisor/cloud-hypervisor.git
cd cloud-hypervisor

cargo build --release
sudo setcap cap_net_admin+ep ./target/release/cloud-hypervisor

此时构建好的 cloud-hypervisor 二进制文件在 ./target/release/ 目录下,可以执行命令看一下版本:

$ ./target/release/cloud-hypervisor --version

cloud-hypervisor v48.0-51-g68f9e8244

文件大小 3.9M. 真不大:

ls -lh ./target/release/cloud-hypervisor   
-rwxrwxr-x 2 sky sky 3.9M Oct 16 11:17 ./target/release/cloud-hypervisor

安全起见,不用 master 分支构建,改用最新的 release tag,然后采用静态链接:

rm -rf target

git checkout v48.0
cargo build --release --target=x86_64-unknown-linux-musl --all
sudo setcap cap_net_admin+ep ./target/x86_64-unknown-linux-musl/release/cloud-hypervisor

./target/x86_64-unknown-linux-musl/release/cloud-hypervisor --version
cloud-hypervisor v48.0

ls -lh ./target/x86_64-unknown-linux-musl/release/cloud-hypervisor 
-rwxrwxr-x 2 sky sky 4.0M Oct 16 15:31 ./target/x86_64-unknown-linux-musl/release/cloud-hypervisor

静态链接也才4M,没大多少.
