[pkg-lxc-devel] Bug#980206: (LXC: lxc-start fails and cgroup IO error

[shan.bharani at gmail.com]

Package: lxc
Version: 1:4.0.5-2


I would like to file a bug for this.

The recent update of packages made lxc malfunction. Unable to start
containers.I have also noted that "Input/ouput Error" in /var/lib/lxcfs
directory. I dont think this is disk IO issue as this can reproduced. I
do have a VM with debian-bullseye-DI-alpha3-amd64-DVD-1.iso. I was able
create a lxc container there and it worked fine. However when I
upgraded to the latest packages I can see the same problem there.

Unable to find the package causing the problem.
