Hi,
I use Debian 6.0.6 amd64 as host system with openvz kernel:
Linux 2.6.32-5-openvz-amd64 #1 SMP Sun May 6 05:21:56 UTC 2012 x86_64 GNU/Linux
and vzctl version 3.0.24
I am created OpenVZ container using official template:
ubuntu-12.04-x86_64.tar.gz
But, after creation i can't enter to this new container:
vzctl enter 9006
enter into CT 9006 failed
Unable to open pty: No such file or directory
Here is debug output
strace -ff vzctl enter 9006 2>&1 | tee strace-9006.log
