Information

Virtuozzo is standardized on general Linux components, and one of major advantages of this approach is the extremely easy templates installation.

As all other components of Virtuozzo, OS templates as well as application templates can be installed through yum.

For older versions of Virtuozzo hypervisor and Virtuozzo containers for Linux check this article:

Typical templates operations by example

Example: Install Ubuntu 12.04 64-bit OS template

[root@pcs6 ~]# yum search ubuntu-12.04-x86_64-ez
Loaded plugins: fastestmirror
Repository cl-updates is listed more than once in the configuration
Loading mirror speeds from cached hostfile
* cl-base: repo.cloudlinux.com
=============================================================== N/S Matched: ubuntu-12.04-x86_64 ===============================================================
...
ubuntu-12.04-x86_64-ez.noarch : Ubuntu GNU/Linux 12.04 (for AMD64/Intel EM64T) OS EZ template
...
[root@pcs6 ~]# yum install ubuntu-12.04-x86_64-ez.noarch

Example: Find application templates for CentOS 6 64-bit

[root@pcs6 ~]# yum search centos-6-x86_64 | sort
========================= N/S Matched: centos-6-x86_64 =========================
centos-6-x86_64-ez.noarch : CentOS 6 (for AMD64/Intel EM64T) EZ OS Template

Example: Update Plesk 11 EZ template for CentOS 6 64-bit

[root@pcs6 ~]# yum update pp11-centos-6-x86_64-ez.noarch

NOTE: yum only manipulates EZ templates RPM packages, but it does not affect template caches. After installing or updating the OS template it is necessary to update cache:

[root@pcs6 ~]# vzpkg update cache OSTEMPLATENAME

Troubleshooting

If there is any issue with templates manipulations go through basic troubleshooting steps:

1. Verify there are correct yum repositories for EZ templates present and enabled:

   [root@pcs6 ~]# yum repolist
   Loaded plugins: fastestmirror
   Repository cl-updates is listed more than once in the configuration
   Loading mirror speeds from cached hostfile
   * cl-base: repo.cloudlinux.com
   repo id                                  repo name                                               status
   centos-vault-os                          CentOSVault OS for outdated CentOS 6.1 - x86_64         6187+1
   centos-vault-updates                     CentOSVault Updates for outdated CentOS 6.1 - x86_64    1247+6
   cl-base                                  CloudLinux Base                                           6474
   ez-templates                             Parallels Cloud Server - EZ templates                     1058
   ez-templates-32                          Parallels Cloud Server - EZ templates (32 bits)           1073
   parallels-cloud-server                   Parallels Cloud Server Base                               2315
   parallels-cloud-server-updates           Parallels Cloud Server Updates                              54
   repolist: 18408
   

   If repositories ez-templates and ez-templates-32 are showing 0 packages, make sure they are properly configured:

   [root@pcs6 ~]# grep -E 'mirror|baseurl|enabled' /etc/yum.repos.d/ez-templates.repo
   mirrorlist=http://updates.cloudserver.parallels.com/mirrors/templates-x86_64
   enabled=1
   mirrorlist=http://updates.cloudserver.parallels.com/mirrors/templates-i386
   enabled=1
   

2. Clean and update yum metadata:

   [root@pcs6 ~]# yum clean metadata && yum update metadata
