4.2. Converting from CentOS 8¶
To be eligible for conversion, the system must not be running cPanel and Plesk or have package repositories configured other than official and EPEL.
If conversion fails with “[Errno 24] Too many open files”, try increasing the corresponding limit, which is 1024 by default, and restart the conversion. For example, run
ulimit -n 10240 to increase the limit of open files to 10240. It will last until the end of the session.
To convert a CentOS 8 installation to Virtuozzo Linux 8, do the following:
Log in as the root user.
vzdeploy8script and mark it as executable:
# wget http://repo.virtuozzo.com/vzlinux/vzdeploy/vzdeploy8 # chmod 755 vzdeploy8
The script is also available at GitHub.
Run the conversion script:
The script will swap the CentOS repositories with the Virtuozzo Linux ones and replace the required packages.
Reboot to the Virtuozzo Linux 8 kernel.
