Hello,
I need migrate Ubuntu 8.04 from OpenVZ (Proxmox 3) to LXC (Proxmox 5). I added 8.04 version to /usr/share/perl5/PVE/LXC/Setup/Ubuntu.pm so migration works but I am not able to start the container. I get:

Code: 
# lxc-start 100
lxc-start: 100: lxccontainer.c: wait_on_daemonized_start: 856 No such file or directory - Failed to receive the container state
lxc-start: 100: tools/lxc_start.c: main: 330 The container failed to start
lxc-start: 100: tools/lxc_start.c: main: 333 To get more details, run the container in foreground mode
lxc-start: 100: tools/lxc_start.c: main: 336 Additional information can be obtained by setting the --logfile and --logpriority options

Is it possible to fix it to get the container to work please?
 
You should start lxc with more debugging in order to get a glimpse what's happening:

Code: 
lxc-start -lDEBUG -o YOURLOGFILE.log -F -n 100


It have have something to do with the init system used in the old ubuntu.
 
Thank you for replay. Here is output in logfile:

what you did will not suffice. those version limitations are there for a reason :)

please see these[0] instructions for converting openvz containers to lxc.

Hi,
I read instructions but I didn't found any usable advice. I don't know why pre-start try to open file /etc/init/tty1.conf.tmp.6571. Here is my fstab:

Code: 
tmpfs      /tmp      tmpfs      noexec,nosuid,size=2G      0     0
tmpfs      /var/tmp      tmpfs      noexec,nosuid,size=2G      0     0

Nobody tried to migrate Ubuntu 8.04 from OpenVZ to LXC? If it is not possible than tell me .. I can try to find another way :)
 
Hi again,

I fixed it by:

Code: 
pct mount 100 
mkdir /var/lib/lxc/100/rootfs/etc/init 
pct unmount 100

After that container starts without errors and it seems good.

Thank you for hints which helped me to fix the issue.
