vm快照例子

1. 开启嵌套虚拟化

limactl start --1name=ubuntu --cpus=8 --memory=16 --containerd none --vm-type=vz --nested-virt template://ubuntu-24.04

2. 下载安装golang

[ go1.27.1.linux-arm64.tar.gz](https://go.dev/dl/go1.27.1.linux-arm64.tar.gz)

rm -rf /usr/local/go && tar -C /usr/local -xzf go1.27.1.*

export PATH=$PATH:/usr/local/go/bin

3.安装docker

sudo apt update

sudo apt install -y ca-certificates curl

sudo install -m 0755 -d /etc/apt/keyrings

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

sudo chmod a+r /etc/apt/keyrings/docker.gpg

echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt update

sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

4.安装kubectl

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/arm64/kubectl"

5. git clone https://github.com/agent-substrate/substrate.git

hack/create-kind-cluster.sh

go install ./cmd/kubectl-ate

KIND_CLUSTER_NAME=kind ./hack/run-microvm-demo-kind.sh

(ko resolve -f - took 9.336s)

[step]: Waiting for the ate-demo-counter-microvm/counter-microvm golden snapshot...

[run-microvm-demo]: Demo applied. Next steps:

1. Inspect the actor template (its golden snapshot is already Ready):

kubectl-ate --context=kind-kind get actor-templates -a ate-demo-counter-microvm

2. Create an actor in the template's atespace (kubectl·-ate; install with: go install ./cmd/kubectl-ate):

kubectl-ate --context=kind-kind create actor my-counter-1 -a ate-demo-counter-microvm \

--template counter-microvm

3. Port-forward the atenet-router and curl the in-RAM counter:

kubectl --context=kind-kind port-forward -n ate-system svc/atenet-router 8000:80 &

curl -X POST \

-H "ate-target-actor: ate-demo-counter-microvm/my-counter-1" http://localhost:8000

Increment, suspend (kubectl ate suspend actor my-counter-1 -a ate-demo-counter-microvm),

resume on another worker, and confirm the count continues — the guest memory snapshot round-tripped.

4.快照和恢复虚拟机行命令

kubectl ate suspend actor my-counter-1 -a ate-demo-counter-microvm

kubectl ate resume actor my-counter-1 -a ate-demo-counter-microvm
