Re: [cc-devel] Issues when loading container image by CC 2.1

Thanks Julio, Graham. First of all, my issue is fixed, and I am able to load container image completely by Clear Container. Then several things I did and findings accordingly. 1. I firstly upgraded cc-oci-runtime to 2.1.2 by `sudo apt-get install cc-oci-runtime` which only upgrades the single package cc-oci-runtime, and it reports error at the beginning that unable to restart cc-proxy.socket, as cc-proxy.service has already active, refusing. 2. So I disable cc-proxy.socket by `sudo systemctl stop cc-proxy.socket` and `sudo systemctl disable cc-proxy.socket`. Still report the error when installing cc-oci-runtime. 3. I reboot my Ubuntu, this time upgrading cc-oci-runtime is successful. Restart cc-proxy.socket by `sudo systemctl enable cc-proxy.socket` and `sudo systemctl start cc-proxy.socket` 4. Till now, I still faced the same issue that docker run with CC runtime will stuck in the middle when loading container image. 5. I did a system upgrade by `sudo apt-get ugprade`, which upgrades docker-engine, clear-containers-image, as well as other system packages. 6. Afterwards, docker-engine was upgrade to 17.03.1, and I tried both Docker runtime (runc), and CC runtime (cor), they can load container image completely. 7. Then I did a downgrade of docker-engine back to 1.12.1, the issue is still gone, I think it is fixed at this time (or maybe at step 6). Following that, I guess there might be some system libraries or upgrade that I missed to cause the issue. I will use it more and see if the issue appears again. Also upgrading cc-oci-runtime seems to have issues with cc-proxy.socket, users have to manually disable cc-proxy service firstly so as to make upgrade successfully. FYI. And to answer Graham's questions, 1. It is the only/first container I've launched. 2. It is a bare metal installation, I didn't use a virtual machine. Docker and CC are installed on physical Ubuntu 16.04 host environment. 3. Host machine has 16GB mem and 470GB free space out of 480G storage.
