Chapter 1. Requirements
1.1. Red Hat Virtualization Manager Requirements
1.1.1. Hardware Requirements
The minimum and recommended hardware requirements outlined here are based on a typical small to medium-sized installation. The exact requirements vary between deployments based on sizing and load.
Hardware certification for Red Hat Virtualization is covered by the hardware certification for Red Hat Enterprise Linux. For more information, see https://access.redhat.com/solutions/725243. To confirm whether specific hardware items are certified for use with Red Hat Enterprise Linux, see https://access.redhat.com/ecosystem/#certifiedHardware.
| Resource | Minimum | Recommended |
|---|---|---|
| CPU | A dual core CPU. | A quad core CPU or multiple dual core CPUs. |
| Memory | 4 GB of available system RAM if Data Warehouse is not installed and if memory is not being consumed by existing processes. | 16 GB of system RAM. |
| Hard Disk | 25 GB of locally accessible, writable disk space. | 50 GB of locally accessible, writable disk space. You can use the RHV Manager History Database Size Calculator to calculate the appropriate disk space for the Manager history database size. |
| Network Interface | 1 Network Interface Card (NIC) with bandwidth of at least 1 Gbps. | 1 Network Interface Card (NIC) with bandwidth of at least 1 Gbps. |
1.1.2. Browser Requirements
The following browser versions and operating systems can be used to access the Administration Portal and the VM Portal.
Browser support is divided into tiers:
- Tier 1: Browser and operating system combinations that are fully tested and fully supported. Red Hat Engineering is committed to fixing issues with browsers on this tier.
- Tier 2: Browser and operating system combinations that are partially tested, and are likely to work. Limited support is provided for this tier. Red Hat Engineering will attempt to fix issues with browsers on this tier.
- Tier 3: Browser and operating system combinations that are not tested, but may work. Minimal support is provided for this tier. Red Hat Engineering will attempt to fix only minor issues with browsers on this tier.
| Support Tier | Operating System Family | Browser |
|---|---|---|
| Tier 1 | Red Hat Enterprise Linux | Mozilla Firefox Extended Support Release (ESR) version |
| Tier 2 | Windows | Internet Explorer 11 or later |
| Any | Most recent version of Google Chrome or Mozilla Firefox | |
| Tier 3 | Any | Earlier versions of Google Chrome or Mozilla Firefox |
| Any | Other browsers |
1.1.3. Client Requirements
Virtual machine consoles can only be accessed using supported Remote Viewer (virt-viewer) clients on Red Hat Enterprise Linux and Windows. To install virt-viewer, see Installing Supporting Components on Client Machines in the Virtual Machine Management Guide. Installing virt-viewer requires Administrator privileges.
Virtual machine consoles are accessed through the SPICE protocol. The QXL graphical driver can be installed in the guest operating system for improved/enhanced SPICE functionalities. SPICE currently supports a maximum resolution of 2560x1600 pixels.
Supported QXL drivers are available on Red Hat Enterprise Linux, Windows XP, and Windows 7.
SPICE support is divided into tiers:
- Tier 1: Operating systems on which Remote Viewer has been fully tested and is supported.
- Tier 2: Operating systems on which Remote Viewer is partially tested and is likely to work. Limited support is provided for this tier. Red Hat Engineering will attempt to fix issues with remote-viewer on this tier.
| Support Tier | Operating System |
|---|---|
| Tier 1 | Red Hat Enterprise Linux 7.2 and later |
| Microsoft Windows 7 | |
| Tier 2 | Microsoft Windows 8 |
| Microsoft Windows 10 |
1.1.4. Operating System Requirements
The Red Hat Virtualization Manager must be installed on a base installation of Red Hat Enterprise Linux 7 that has been updated to the latest minor release.
Do not install any additional packages after the base installation, as they may cause dependency issues when attempting to install the packages required by the Manager.
Do not enable additional repositories other than those required for the Manager installation.
