Creating your own certificates for DirectAdmin

Advantage of creating your own certificates:
You can switch DirectAdmin to use SSL instead of plain text. -> https instead of http on port 2222.

If you do not have your own certificates, you’ll need to create your own:

And then

Service Container on a Parallels Virtuozzo Containers hardware node can be created using ‘vzsveinstall‘ utility:

- DISTRIB_DIR - path to Virtuozzo distribution directory hierarchy on a server.
- SERVICE_CT_IP - IP address to be assigned to Service Container;

In case you have downloaded Virtuozzo distributive already (example for 64-bit PVC 4.0) as file “virtuozzo-4.0.0-${build_version}-x86_64.sfx”, please extract it in the following way:

Create Service Container then using this command (make sure old Service Container #1 does not exist):

Please refer to man page on ‘vzsveinstall‘ utility for additional information.

updating Parallels Plesk Panel inside Parallels Virtuozzo Containers using EZ templates.

Install the vzaiproxy package on the hardware node. You can download this package from http://autoinstall.plesk.com/vzaiproxy

Change line 16 in file /etc/init.d/vzlinkmgr to the following:

Change line 32 in file /usr/sbin/vzaiproxy to the following:

Install all EZ templates from Parallels Plesk Panel distribution on the hardware node.
Run Parallels Plesk Panel installation or upgrade using Parallels Products Installer (either via the web-interface or command line interface) or Parallels Plesk Panel GUI (Home Page > Updates).

Follow the instructions presented on the screen to complete the upgrade.

How to check if CPU supports hardware virtualization (VT technology)

To run KVM, you need a processor that supports virtualization. For Intel processors this extension has name INTEL-VT, for AMD processors it has name AMD-V.

To see if your processor supports one of these technologies, please run the following command under Linux:

If nothing is printed, it means that your CPU does not support hardware virtualization. Otherwise, it does – but you still need to make sure that virtualization is enabled in the BIOS. If the svm flag is returned then your processor supports AMD-V or if the vmx flag is returned then your processor supports Intel VT.

If you are installing Parallels Plesk Panel inside a PVC, it is strongly recommended to increase Container parameters as follows:

# Auxiliary parameters

# Disk quota parameters (in form of softlimit:hardlimit)

# Secondary parameters
