Need help or any hints...have setup more than 20 OPenVZ servers and have never seen this problem. Details below.

Google shows no exact error message match.

Thanks!

Guess I will have to download the source and analyze.

If a bug is found I will report at bugzilla.

Cheers!

This works...

# wget http://download.openvz.org/utils/vzctl/3.0.23/src/vzctl-3.0.23-1.src.rpm
# rpm -i vzctl-3.0.23-1.src.rpm
# cd /usr/src/redhat/SOURCES
# tar xvjf vzctl-3.0.23.tar.bz2
# cd vzctl-3.0.23
# ./configure --enable-bashcomp --enable-logrotate
# make
# make install

The above complile from sources placed new utils in /usr/local.

And viola...now it works! Why is the question? More rudimentary investigating...

So on my server set of new CentOS 5.3 x86_64 servers with yum installed OpenVZ kernel:

2.6.18-128.2.1.el5.028stab064.7

I had this thread's problem.

Summary: Had to compile from source to get chkpnt to work.

Hi,

have you installed the OpenVZ tools (esp. vzclt) for x86-64 as well or only the i386 Version ?

Thanks Thorsten,

That was exactly the problem. What was very confusing is that ALL the other vzctl functions worked perfectly. So I guess the chkpnt loads a .so (like M$ dll's) that the other parts of vzctl do not use.

So I guess this problem was based on some yum confusion but only regarding the utils pkg. I think yum/rpm should be improved on or the underlying .spec files.

For now I have to be very careful and not yum install everything without the proper checks.

A test suite would also be cool. We will make one.

Thanks again for your on the mark comment!
