| − | === 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

| − | ''Note'' This was tested with CentOS VE.

| − | * 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
