Upgrading Parallels Virtuozzo Containers

The following table lists the types of "Host OS" + "Parallels Virtuozzo Containers" upgrades supported in Parallels Cloud Server 6.0:

To upgrade a system:

1. Prepare for the upgrade using the instructions in Preparing for the Upgrade .
2. Install Parallels Cloud Server 6.0. For an example, see Example: Upgrading Parallels Virtuozzo Containers .
3. If necessary, configure Containers to use the VSwap memory parameters. To do this, apply one of the available VSwap configuration files to the Container. For example, to configure Container 101 to use the ve-vswap.1024MB.conf-sample configuration file, you can run the following command:

   # prlctl set 101 --applyconfig vswap.1024MB

   All VSwap configuration files are stored in the /etc/vz/conf directory on the server; so you can explore this directory to find the right configuration file for your Container. For detailed information about VSwap parameters, consult the Parallels Cloud Server 6.0 User's Guide .
