[CRIU] Can't move into blkio//lxc/ycu/tasks (-1/-1): No such file or directory

[Ruslan Kuprieiev]

Oh, damn it! I completely forgot about --manage-cgroups =D.
Sorry for the noise.

linuxchyu at sina.com, I know it's been long time ago, but did you solve

If not, maybe you forgot about --manage-cgroups too?

Thanks,
Ruslan
