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
