Just following up my own question. Doesn't the display get confused of which one to display?
The screen is showing VE0 or the container you have installed full X Server on?
What if I don't have full XServer installed , I just want to show the command line screen of the container on screen . Without doing vzctl enter VEID , can I still view the container by using the method in this thread?
What do I do after I have done the following:
Mount /proc from HN to VE. i.e.:
# umount -l /vz/root/$VEID/proc
# mount -t proc proc /vz/root/$VEID/proc
