Hi Daniel What I can reproduce is that you get a "Resource temporarily unavailable" message for this line
quartz:/home/ola/svn/t# vzctl enter 201 --exec exit ; read a entered into CT 201 exit root@test1:/# exit logout exited from CT 201 bash: read: read error: 0: Resource temporarily unavailable But not when you do it without --exec. quartz:/home/ola/svn/t# vzctl enter 201 entered into CT 201 root@test1:/# exit logout exited from CT 201 quartz:/home/ola/svn/t# read a ^C No problem this time. And not with: quartz:/home/ola/svn/t# vzctl enter 201 entered into CT 201 root@test1:/# read a ^C root@test1:/# exit logout exited from CT 201 And no problem here. When you do a enter and --exec I do not think you actually have any stdin available. I may be wrong here but enter is special in that sense. I think the same applies when you do chroot. If you want I can forward this bug report to upstream but first I need to understand a bit more about your problem. Is it one of the following? 1) You do not have a stdin in commands that you use with --exec ? 2) That you get resource unavailable also after you have exited from the CT? 3) Something else?
