Container enter failed

Revision as of 17:50, 26 March 2008 by Sandro magri (talk | contribs) (alternative solution for the problem)

Problem: container created succesfully and started. But when trying to do

vzctl enter 101 

you get

container enter failed(?)

Using strace, you see:

# strace -ff vzctl enter
....
fstat64(...st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0)...) fail
....

Solution: Recompile the kernel with the following option:

CONFIG_LEGACY_PTYS=y

Another solution:

enter the VE manually creating the LEGACY_PTYS devices

vzctl exec  101 /sbin/MAKEDEV tty
vzctl exec 101 /sbin/MAKEDEV pty
vzctl enter 101

To save the changes create a file to force udev making LEGACY_PTYS:

cat > /etc/udev/makedev.d/51-udev.nodes
# These device have to be created manually
tty0
tty1
tty2
tty3
tty4
tty5
tty6
tty7
tty8
tty9
ttyp0
ttyp1
ttyp2
ttyp3
ttyp4
ttyp5
ttyp6
ptyp0
ptyp1
ptyp2
ptyp3
ptyp4
ptyp5
