[Lxc-users] copy from OEL template does not work

[Tony Su]

Also,
Without an error message more informative than a simple segfault, who knows?

Recommend:
Search your Host syslogs for a more informative error message
If not in a message, post the Container config file somewhere where
someone can inspect (eg Pastbin)

I assume that you're copying to/from separate physical machines or
this is only an intellectual exercise? Of course, copying to/from a
Host and a Container on the Host doesn't require SCP (eg networking),
there are many alternatives like mounting a shared directory or simply
copy/paste if your User account has sufficient permissions.
