It looks like you called your container "VM", not "container". What
does lxc-ls show? Are you sure the host has network connectivity with
the container? (ie. are you resolving to the container? Can you ping
it?) If you think its ssh protocol/authentication related you might try
to just ssh in with -vv to see what is going on.

rsyncd is not run in the Oracle container by default, so unless you
have enabled it I wouldn't expect it to work :)
