You may receive the following message on entering a VPS:

# vzctl enter 101

enter into VE 101 failed

Unable to open pty: No such file or directory

The reason behind this is the missing tty/pty files . You can create it using the MAKEDEV program, execute the following commands on the host server ( main node ).

# vzctl exec VEID /sbin/MAKEDEV tty
# vzctl exec VEID /sbin/MAKEDEV pty

Replace VEID with your actual vps id . In our example its 101 .

Restart vps .

#vzctl restart VEID

Thats a temporary fix. To Fix this issue permanently follow the below steps after entering to your vps client node (101 in our case) .

1) #vzctl enter VEID

2) Edit the file /etc/rc.sysinit

3) Comment the line
#/sbin/start_udev

4) Add the following lines after /sbin/start_udev:
/sbin/MAKEDEV tty
/sbin/MAKEDEV pty

5) Reboot your VPS client node .
vzctl restart VEID

You can also access the file /etc/rc.sysinit for the node 101 from the main VPS node . It should be from /vz/private/VEID/etc/rc.sysinit .

You can also try the below steps by updating the startup files

# vzctl exec VEID update-rc.d -f udev remove
# vzctl restart veid

Above fixes may not work for ubuntu servers . In that case you can try the below command

# vzctl exec VEID ‘dpkg –force-depends –purge udev’
