Trying to build newest 2.6.20 kernel with checkpoint and restore included:

CC [M] kernel/cpt/cpt_process.o
kernel/cpt/cpt_process.c: In function ‘dump_one_process’:
kernel/cpt/cpt_process.c:793: error: ‘struct nsproxy’ has no member named ‘namespace’
kernel/cpt/cpt_process.c:807: error: ‘struct nsproxy’ has no member named ‘namespace’
kernel/cpt/cpt_process.c:808: error: ‘struct nsproxy’ has no member named ‘namespace’
kernel/cpt/cpt_process.c:838: warning: comparison of distinct pointer types lacks a cast
make[3]: *** [kernel/cpt/cpt_process.o] Error 1

I have looked at nsproxy structure in include/linux/nsproxy.h

struct nsproxy {
atomic_t count;
spinlock_t nslock;
struct uts_namespace *uts_ns;
struct ipc_namespace *ipc_ns;
struct mnt_namespace *mnt_ns;
struct pid_namespace *pid_ns;
};

My system is ubuntu 7.04

Regards,
Ernad

Checkpointing is not supported in current 2.6.20 OpenVZ series, so you should turn CONFIG_VZ_CHECKPOINT option off in you kernel config.

Thank you,
Vasily.

Well, there will be a Linux Symposium on June the 27th. I'm pretty sure, that before it CPT will work on 2.6.20. However, I know a good method how to accelerate the process: please, fill the bug report in bugzilla.openvz.org! Wink

Thanks,
Vasily.

This is out of this topic, but it seems to me there is large improvement in 2.6.20 ovz kernel since ovz005.

Performance and stability on my laptop with ovz005 was quite bat. With this last build situation is much much better Smile
