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 :)
