The VPS’es that have problems with connecting and entering,it tends to be a small problem either with tty/pty devices OR udev. You will be greeted with an error message while accessing a VPS from the host server:
enter failed
enter into Container VEID failed
either the pty/tty devices are missing OR having incorrect permissions. You will have to create them on the container using the MAKEDEV program which is use to create devices in /dev. The following commands will have to be executed from the host server to create those devices and restart the container:
vzctl exec VEID /sbin/MAKEDEV tty
vzctl exec VEID /sbin/MAKEDEV pty
vzctl restart VEID
If creating the devices doesn’t fix the issue, update the startup files and restart the container:
vzctl exec VEID update-rc.d -f udev remove
vzctl restart VEID
