[Users] virtuozzo base OS and new centos 8 orientations

[Denis Silakov]

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

I tested vzconvert8 from fresly installed vzdeploy8 (vzdeploy8-1.0.30-1.vl7.x86_64)
it failed :

#  vzconvert8 convert tomcatsrv9

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
