Running openvz on Ubuntu Hardy. Couldn't figure out how to make vzyum work on that platform so I went to a Centos 5 system to build a container and then migrate it.

First problem:

vzyum 733 install yum
ERROR: vzrpm43 path not found: /usr/share/vzpkgtools/vzrpm43
ERROR: RPM python path not found: /lib/python2.4/site-packages

OK so I noticed that rpm was 44 not 43, so I changed the /vz/template/centos/4/i386/config/rpm to 44 from 43. I have no idea who maintains that file since it isn't in any package according to rpm -qf.

Now I get :
vzyum 733 install yum
exec /usr/share/vzyum/bin/yum -c /vz/template/centos/4/i386/config/yum.conf --installroot /vz/root/733 --vps=733 install yum

File "/usr/share/vzyum/lib/yum/config.py", line 384, in _getsysver
idx = ts.dbMatch('provides', self.getConfigOption('distroverpkg'))
TypeError: rpmdb open failed

I have no idea what to do about that but I do have another Centos 5 system running openvz so off to that system.

vzyum 733 install yum

Complete!

So that part worked, now to try to migrate it back to Hardy.

vzmigrate --online -r no 192.168.2.44 733

OK that didn't work so let's checkpoint it and try to restore on the other system.

We're half way there!

vzctl restore 733 --undump --dumpfile 733

So whay isn't there a config file? Oh well, that's easy enough to fix.

I'm tired of trying things that don't work. Can someone help me get yum installed on a centos 4 minimal template running on a Hardy VE0 platform?

Thanks,
Jim.

Hi,

you've done a lot of work and got a lot of problems Smile

ERROR: RPM python path not found: /lib/python2.4/site-packages

I guess you should install this http://wiki.openvz.org/Download/vzrpm43/4.3.3-7_nonptl.6
utilities.

I doubt that it should have been done.

I really hope that the first and the second points help to solve first problem.

Could you do that command with -v option but I think that you've pointed out the problem:

HZ mismatch can cause the problem.
If it is possible you can recompile the kernel.

4. Anyway I came across this thread nad think it could be very useful in this case.

Unfortunately I don't try that but hope it works.

If you can't get vzyum to work (which is problematic on newer system, especially x86_64), you can manually install yum inside of your container using rpm.

If your container is new and you don't care about destroying it and starting over, you can use one of the contributed pre-created OS Templates I've created (that I'm trying to keep updated by uploading a new one once a month) that has yum already installed.

For manually installing yum into your container see the following wiki article:

http://wiki.openvz.org/Install_yum

That might be a little outdated if any of the packages have been updated... so find a CentOS repository and copy the links to the packages. Oh, and you don't have to do a separate rpm -ivh for each individual package... you can do them all at once. Just put a space between package names. If the package list is incomplete and it stills throws up some unresolved dependencies (rpm doesn't resolve deps), then you just need to keep tacking on all of the needed packages until you have everything. I have used that recipe from the wiki and it worked for me.

If you want my contributed pre-created OS Templates, see here:

http://download.openvz.org/template/precreated/contrib/

They are the CentOS (and Fedora) files with dates as part of the filenames... and are current as of the date given (last Friday when I wrote this).

Unfortunately I don't try that but hope it works.

That was the trick. I did have to install a half dozen other packages to satisfy dependencies, but eventually that worked.

To document what I did in hopes it will help others, here's the script I used to successfully install yum:


rpm -Uvh  http://mirror.centos.org/centos-4/4/os/i386/CentOS/RPMS/gmp-4.1.4-3.i386.rpm
rpm -Uvh  http://mirror.centos.org/centos-4/4/os/i386/CentOS/RPMS/readline-4.3-13.i386.rpm

rpm -Uvh http://mirror.centos.org/centos-4/4/os/i386/CentOS/RPMS/libxml2-2.6.16-10.i386.rpm
rpm -Uvh http://mirror.centos.org/centos-4/4/os/i386/CentOS/RPMS/libxml2-python-2.6.16-10.i386.rpm
rpm -Uvh http://mirror.centos.org/centos-4/4/os/i386/CentOS/RPMS/expat-1.95.7-4.i386.rpm

rpm -Uvh http://mirror.centos.org/centos-4/4/os/i386/CentOS/RPMS/yum-2.4.3-4.el4.centos.noarch.rpm
yum -y update

This was for a Centos 4.4 system.

Thanks,
Jim.

Thanks, eventually the manual install worked as I reported in a previous message.

And thanks a bunch for your efforts in maintaining the precreated templates. Very Happy

I've used a few and really appreciate them. I didn't know before who to thank.

Regards,
Jim

That was quite painful... because your OS Template was for CentOS 4.4 and you had to find 4.4 packages. 4.6 is the current CentOS release and I think all OS Templates should be as current as possible. 4.7 comes out any-day now.

My dated contrib OS Templates are current as of the dates in the names.

Yes, unfortunately I'm running a test platform and it has to run the same OS as the production environment. Updating the production environment is something we don't like to do very often.

Thanks again,
Jim.

Well, part of the "Enterprise" distro concept is that the updates are totally compatible and pain free so I don't recommend hovering at an older version.

Of course that is outside the scope of OpenVZ and your mileage may vary.
