Parallels Virtuozzo Containers 4.6 allows you to upgrade servers running OpenVZ

(www.openvz.org) to Parallels Virtuozzo Containers 4.6. To do this:

1 Update OpenVZ to its latest version. You can download the latest versions of OpenVZ

packages from http://download.openvz.org.

2 Back up the physical server and all Containers on this server. For example, you can use the

Acronis

True Image Echo™ Enterprise Server (a free trial version is available at

http://www.acronis.com/enterprise/download/ATIESWin/) software to create a backup copy

of your system and to restore it if something goes wrong during the upgrade.

3 Download the vzinstall-linux-i386.bin or vzinstall-linux-

x86_64.bin utility (for the x86 or x86-64 version of Parallels Virtuozzo Containers 4.6,

respectively) from the Parallels web site.

The process of downloading and installing Parallels Virtuozzo Containers 4.6 with the

vzinstall-linux-i386.bin and vzinstall-linux-x86_64.bin utilities is

the same. Therefore, we use a generic term vzinstall-linux.bin to indicate both

utilities throughout this document.

4 Make the vzinstall-linux.bin file executable:

# chmod a+x vzinstall-linux.bin

5 Execute the vzinstall-linux.bin utility. You can run vzinstall-linux.bin in

one of the following modes:

 In the 'Download and install' mode, the utility automatically starts the upgrade once it

downloads the Parallels Virtuozzo Containers 4.6 installation files to the server.

 In the 'Download only' mode, the utility only downloads theParallels Virtuozzo

Containers 4.6 installation files but does not install them on the server. You can copy the

downloaded files to the server where you plan to upgrade to Parallels Virtuozzo

Containers 4.6 and execute the following command:

# ./virtuozzo-4.6.0-<build_version>-<arch>.sfx

Detailed information on the vzinstall-linux.bin utility is provided in the Parallels

Virtuozzo Containers 4.6 Installation Guide. Consult this guide if you need more

information about specific steps.

Note: The current version of Parallels Virtuozzo Containers supports upgrading servers running

CentOS 4 and 5 and Gentoo. However, for CentOS 4 and Gentoo, you first need to upgrade the

Host operating systems to CentOS 5.
