Broken OS template cache

I got a task to upgrade container with Fedora core 7 to Fedora Core 8. From available information such operation can be run as

 

vzpkg upgrade VE_ID

So I without any thoughts back up container and run upgrade. But upgrade finished with error about vzquota. after googling all what I found, was information that I should recreate cache. This operation was finished with errors too.

 

So my workaround is:

 

1. backup container

2. download OS  template from http://www.parallels.com/products/virtuozzo/templates/catalog/

3. install downloaded OS template with force option

 

vzpkg install template OS_TPL –force

 

4. recreate OS cache

 

vzpkg create cache OS_TPL

vzpkg update cache OS_TPL’

 

5. have fun with OS and container upgrade :)
