2.1. Starting Installation

Virtuozzo can be installed from

  • IPMI virtual drives

  • USB drives (see Preparing for Installation from USB Storage Drives)

  • PXE servers (see the Installation via PXE Server guide for information on installing Virtuozzo over the network)


    In Virtuozzo 7, time synchronization via NTP is enabled by default using the chronyd service. If you want to use ntpdate or ntpd, stop and disable chronyd first.

To start the installation, do the following:

  1. Configure the server to boot from the chosen media.
  2. Boot the server and wait for the welcome screen.

2.1.1. Choosing Installation Type

You can install Virtuozzo 7 in one of the following modes:

Your further installation steps will differ depending on the chosen mode.

2.1.2. Enabling Forced Detection of SSDs

Certain solid-state drives (SSDs) may not be autodetectable by the installer. This may result in issues when you create or join Virtuozzo Storage clusters. To avoid this problem, you can force the installer to identify the required drives as SSDs by doing the following:

  1. Select the required installation option (e.g., Install Virtuozzo 7) and press E to start editing it.

  2. Add ssd_hack=sd<N>[,...] at the end of the line starting with linux /images/pxeboot/vmlinuz. For example:

    linux /images/pxeboot/vmlinuz inst.stage2=hd:LABEL=<VZ7_ISO_image> quiet ip=dhcp \
  3. Press Ctrl-X to start booting the chosen installation option.

The installer should identify the specified drives as SSDs.
