[Users] virtuozzo base OS and new centos 8 orientations

Yes, need to look into CT config (/vz/private/7ed1de35-75bc-4137-977a-b4055067fb0a/ve.conf) and turn back 'centos' as template.

well, it looks like I'am in the middle of the process, now it doesn't want to convert anymore

# vzconvert8 convert --log /tmp/idp4mt-convovz8.logidp4mt  idp4mt
7ed1de35-75bc-4137-977a-b4055067fb0a: Conversion aborted: Container's OS template is not supported

althought the CT seems to be keept in centos 8 :

[root at idp4mt ~]# cat /etc/redhat-release
CentOS Linux release 8.3.2011

maybe I need to revert/remove something that the conversion has started ?

thanks .

Probably the issue with gcc is caused by gcc update in VzLinux 8 which is happening right now.
Could you check again, the repos are refreshed now?

And the script considered the problem to be serious enough not to proceed with conversion.

# vzconvert8 convert --log /tmp/idp4mt-convovz8.logidp4mt  idp4mt

Looks like we broke launch without --log option while improving logging.
Will be fixed soon, as a workaround you can use --log option.

Looks a bit strange indeed, vzdeploy was intended to just leave httpd from centos in such cases.

But now we have one more way for converting containers which will probably be more reliable. It utilizes vzpkg tool and should be launched from the server side:

# yum install vzdeploy8
# vzconvert8 convert <CTID>

Hi,

On a brand new centos8 container I get the following error from yum
after running the vzdeloy8 script (with the ignore kernel env set) :

-----

Modular dependency problems:

  Problem 1: conflicting requests
   - nothing provides module(platform:el8) needed by module
httpd:2.4:8030020201104025655:30b713e6-0.x86_64
  Problem 2: conflicting requests
   - nothing provides module(platform:el8) needed by module
python36:3.6:8030020201104034153:24f1489c-0.x86_64
Dependencies resolved.
Nothing to do.

------

I tried removing and reinstalling httpd* but that didn't resolve the error.

Any ideas ?

I feel this is very close now !
Thanks for all your hard work.

Regards

Ian
