Dear Kata Containers Community,

I'm the user of Kata Containers from Haier Corp of China。Now I want your support to resolve my problems.

I run Kata(version:3.2.0) containers on Containerd (v1.7.9) with CNI Network, and the hypervisor is ACRN(V3.2.0) 。Now I can run a kata containers on acrn hypervisor，but the SOS cannot communicate with each other over the cni network，but it works when using hypervisor QEMU。

Here are my steps:

1. Create cni conf file

cat << EOF | tee /etc/cni/net.d/redisnet.conf

{

    "cniVersion": "0.4.0",

    "name": "redisnet",

    "type": "bridge",

    "bridge": "cni0",

    "isDefaultGateway": true,

    "forceAddress": false,

   "ipMasq": true,

    "hairpinMode": true,

    "ipam": {

        "type": "host-local",

        "subnet": "10.77.0.0/16"

    }

}

EOF

2. Create networkspace and add network into it.

ip netns add redisnet

 

export CNI_PATH=/opt/cni/bin

cnitool add redisnet /var/run/netns/redisnet

cnitool check redisnet /var/run/netns/redisnet

I am now able to ping 10.77.0.2.

3. Start a kata container with CNI Network

ctr run  --snapshotter devmapper  --runtime "io.containerd.kata.v2"  --with-ns=network:/var/run/netns/redisnet -d registry2-qingdao.cosmoplat.com/62_edegecloud/ubuntu-vim-ip:22.04 kata-test sh

but the container's eth0 is link down.

Now I cannot ping 10.77.0.2。

could you  please help me figure out where is wrong about my steps? If not wrong ,could you  please help me resolve this problems？

 

Here are some logs and configs of my test.

 

Thanks and Best Regards,

Jason Yang
