# vzctl chkpnt 103
Setup checkpoint...
Error: No checkpointing support, unable to open /proc/cpt: No such file or directory

have you compiled the kernel itself?
check CONFIG_VZ_CHECKPOINT option. is it 'm'?

hi,

no because this option isn't available in my .config-file! i checked the patch-file and there i can find it but i don't know why it's not in the .config...

i added it now and try to compile it... no module available... it was not generated Sad

what i am doing wrong?

cu tb.

+config VZ_CHECKPOINT
+ tristate "Checkpointing & restoring Virtual Environments"
+ depends on SOFTWARE_SUSPEND && VE_CALLS

check that you enabled these 2 options which are required for checkpointing.

that's it

SOFTWARE_SUSPEND was missing because i deactivted the energy save options Wink

now i can compile but i cannot load the module vzcpt...

# modprobe vzcpt     FATAL: Error inserting vzcpt (/lib/modules/2.6.16-026test012/kernel/kernel/cpt/vzcpt.ko): Unknown symbol in module, or unknown parameter (see dmesg)
#dmesg
[...]
vzcpt: Unknown symbol pmd_huge
