Các thùng chứa CentOS LXC của tôi sẽ không bắt đầu nữa trên máy Ubuntu 14.10. Tôi nghĩ rằng vấn đề bắt đầu sau khi khởi động lại, nhưng tôi không chắc chắn.
Tôi đã gặp một vấn đề tương tự sau khi cập nhật yum, khi các tập lệnh init được thay thế bằng các tập lệnh không biết LXC. Họ đã cố gắng bắt đầu udev, v.v ... Nhưng lần này tôi gặp vấn đề này đối với tất cả các phiên bản CentOS, ngay cả đối với những người mới được tạo.

Để tạo tất cả các phiên bản CentOS mà tôi đã sử dụng:

root@ubuntu-mvutcovici:~# cat lxc-mircea.conf
lxc.network.type = veth
lxc.network.link = br0
lxc.network.flags = up
EDIT : Có vẻ như việc thêm lxc.aa_allow_incomplete = 1vào tập tin / var / lib / lxc / stash / config là một cách giải quyết cho vấn đề bắt đầu. Làm cách nào tôi có thể làm cho áo giáp ứng dụng cùng tồn tại trở lại với CentOS LXC?
Từ trang người đàn ông lxc.container.conf:
lxc.aa_allow_incomplete
Apparmor profiles are pathname based. Therefore many file restrictions require mount restrictions to be effective against a determined attacker. However, these mount restrictions are not yet implemented in the
upstream kernel. Without the mount restrictions, the apparmor profiles still protect against accidental damager.
If this flag is 0 (default), then the container will not be started if the kernel lacks the apparmor mount features, so that a regression after a kernel upgrade will be detected. To start the container under partial
apparmor protection, set this flag to 1.
