Issue description
I create CT container have Centos7.4 OS. when i am trying to enter through the VE host using the following command
lxc-attach -n enter 100
i got error
lxc-attach: enter: attach.c: lxc_attach: 1095 Failed to get init pid
there is no problem with container functionality i can able to access it through ssh well. or console via proxmox GUI. i can start and stop the container without any problem, but i can’t access it through node through lxc-attach command
how can i fix this problem?
regards
