[CRIU] Dumping lxc container failed - CRIU 1.6

[Thouraya TH]

Hi all,

May be, cloning container is the source of the problem...


*Does it happen always? What if you try to dump this container again
without restart?*
Did you mean:

lxc-checkpoint -s -D /tmp/dire -n worker1
lxc-start -n worker1  ( i have to restart all process needed inside the
container)
lxc-checkpoint -s -D /tmp/dire1 -n worker1

?




Thanks a lot for help.
Best Regards.
