Virtuozzo Hybrid Server can be installed from
IPMI virtual drives,
USB drives (see Preparing for Installation from USB Storage Drives),
PXE servers (see Installation Using PXE for information on installing Virtuozzo Hybrid Server over the network).
Note

chronydservice. If you want to usentpdateorntpd, stop and disablechronydfirst.
To start the installation, do the following:
- Configure the server to boot from the chosen media.
- Boot the server and wait for the welcome screen.
2.1.1. Choosing Installation Type¶
You can install Virtuozzo Hybrid Server 7 in one of the following modes:
- Graphics. In this mode, you can install Virtuozzo Hybrid Server components with one of the following management interfaces:
- Web-based user interface (default, recommended). The interface consists of Virtuozzo Storage management panel and Virtuozzo Automator management panel (Control Center), see Installing with GUI Management.
- Command-line interface, see Installing with CLI Management.
- Basic graphics (in case of issues with video card drivers), see Installing in the Basic Graphics Mode.
- Graphics via VNC, see Installing via VNC.
- Text (Virtuozzo Storage cannot be installed in this mode), see Installing in the Text Mode.
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:
Select the required installation option and press E to edit it.
Add
ssd_hack=sd<N>[,...]at the end of the line starting withlinux /images/pxeboot/vmlinuz. For example:linux /images/pxeboot/vmlinuz inst.stage2=hd:LABEL=<VZ7_ISO_image> quiet ip=dhcp \ ssd_hack=sdb,sdc
Press Ctrl-X to load the selected installation option.
The installer should identify the specified drives as SSDs.
2.1.3. Installing on USB Drive¶
Aside from regular disks, you can also install Virtuozzo Hybrid Server on a 64GB+ USB drive. In this case, however, you will still need to place the swap partition on a regular HDD/SSD drive. It is also recommended to store logs on a syslog server.
To have a USB drive recognized as an installation destination, configure the installer as follows:
Select the required installation option and press E to edit it.
Add
allow_usb_hddat the end of the line starting withlinux /images/pxeboot/vmlinuz. For example:linux /images/pxeboot/vmlinuz inst.stage2=hd:LABEL=<VZ7_ISO_image> quiet ip=dhcp \ allow_usb_hdd
Note
