WOC9or power,

=== Using strace ===
 
−
 
 
−
You can use [http://linux.die.net/man/1/strace strace] to analyse the command further:
 
−
<pre>
 
−
# strace -ff vzctl enter 101
 
−
....
 
−
fstat64(...st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0)...) fail
 
−
....
 
−
</pre>
 
−
 
 
−
Recompile the kernel with the following option:
 
−
CONFIG_LEGACY_PTYS=y
 
−
 
 
−
=== LEGACY_PTYS ===
 
−
 
 
−
==== Temporary fix ====
 
−
''Note: This is a temporary fix so you can enter the VE.''
 
−
 
 
−
* Create the LEGACY_PTYS devices:
 
−
 
 
−
vzctl exec 101 /sbin/MAKEDEV tty
 
−
vzctl exec 101 /sbin/MAKEDEV pty
 
−
vzctl enter 101
 
−
 
 
−
==== Permanent fix with udev ====
 
−
* For a permanent fix with udev, you will need to force udev to make LEGACY_PTYS:
 
−
 
 
−
cat > /etc/udev/makedev.d/51-udev.nodes
 
−
# These device have to be created manually
 
−
tty0
 
−
tty1
 
−
tty2
 
−
tty3
 
−
....
 
−
ttyp0
 
−
ttyp1
 
−
ttyp2
 
−
ttyp3
 
−
....
 
−
ptyp0
 
−
ptyp1
 
−
ptyp2
 
−
ptyp3
 
−
....
 
−
 
 
−
==== Permanent fix without udev ====
 
−
* Alternatively, you can disable udev:
 
−
 
 
−
Edit the ''/etc/rc.d/rc.sysinit'' file and comment out the ''/sbin/start_udev'' line
 
−
 
 
−
Or you can run the following command:
 
−
 
 
−
sed -i 's|/sbin/start_udev|#/sbin/start_udev|g' /etc/rc.d/rc.sysinit
 
−
 
 
−
''Warning'' Updates to the package which owns this file may revert your changes.
 
−
 
 
−
''Note'' This was tested with CentOS VE.
 
−
 
 
−
=== Debian only ===
 
−
 
 
−
* Enter the VE manually
 
−
CTID=101
 
−
vzctl exec $CTID "mount -t devpts devpts /dev/pts"
 
−
vzctl enter $CTID
 
−
 
 
−
* Remove udev using apt
 
−
CTID=101
 
−
vzctl exec $CTID apt-get remove udev
 
−
vzctl restart $CTID
