Keeping Your System Up To Date 171
Updating Software In Virtual
Machines
To keep software in your virtual machines up to date, you can use the same means you would
use on standalone computers running the corresponding operating systems:
 In Linux-based virtual machines, you can use the native Linux updaters (up2date, yum, or
yast).
 In Windows-based virtual machines, you can use the native Windows updaters (e.g. the
Windows Update tool).
You should regularly run these updaters to ensure that your system has the latest updates and
fixes (including security patches) installed. For more information on native updaters, refer to the
documentation shipped with your operating system.
Updating Containers
Parallels Server Bare Metal provides two facilities to keep your Containers up to date. These
facilities include:
 Updating EZ templates software packages inside a particular Container by means of the
vzpkg utility. Using this facility, you can keep any of the Containers existing on your
Parallels server up to date.
 Updating caches of the OS EZ templates installed on the Parallels server. This facility
allows you to create new Containers already having the latest software packages installed.
