[Thouraya TH]

Hello all :)

I have used criu 1.6. I have done the dumping process of lxc container

*lxc-checkpoint -D /home/dire -n worker1*

dump.log

*lxc-stop*

and

* lxc-checkpoint -r -D ** /home/dire -n worker1*

i have in restore.log:

cause restore problem,because not all kernels support such clone flags
combinations!
