This issue comes with openvz nodes. After the creation of VE, we may face an issue like following,
# vzctl enter 101 enter into VE 101 failed Unable to open pty: No such file or directory
Its solution is simple. Please do the following procedure
# vzctl exec 101 /sbin/MAKEDEV tty # vzctl exec 101 /sbin/MAKEDEV pty # vzctl enter 101
Now do the following, to find the udave package name as follows.
# rpm -qf /etc/udev/makedev.d/50-udev.nodes udev-095-14.9.el5 # rpm -e udev-095-14.9.el5 –nodeps
Now restart that VE ( here 101 ) enjoy.
