4.2. Basic Requirements and Setup

To set up a KVM virtual machine on Red Hat Enterprise 7, your system must meet the following criteria:
Architecture
Virtualization with the KVM hypervisor is currently only supported on Intel64 and AMD 64 systems.
Disk space and RAM
Minimum:
  • 6 GB free disk space
  • 2 GB RAM
Customer Portal registration
To install virtualization packages, your host machine must be registered and subscribed to the Red Hat Customer Portal. To register run the subscription-manager register command and follow the prompts. Alternatively, run the Red Hat Subscription Manager application from ApplicationsSystem Tools on the desktop to register.
If you do not have a valid Red Hat subscription, visit the Red Hat online store to obtain one. For more information on registering and subscribing a system to the Red Hat Customer Portal, see https://access.redhat.com/solutions/253273.
Required packages
Before you can use virtualization, a basic set of virtualization packages must be installed on your computer.

Procedure 4.1. Installing the virtualization packages with yum

To use virtualization on Red Hat Enterprise Linux, the qemu-kvm, qemu-img, and libvirt packages must be installed. These provide the user-level KVM emulator, disk image manager, and virtualization management tools on the host system.
  1. Install the qemu-kvm, qemu-img, libvirt, and virt-manager packages:
    # yum install qemu-kvm qemu-img libvirt virt-manager
  2. Download a binary DVD ISO image from the Red Hat Customer Portal. This example uses Red Hat Enterprise Linux 6 Workstation. The image file will be used to install the guest virtual machine's operating system.

Note

If you encounter any problems during the installation process, see the Troubleshooting section of the Red Hat Enterprise Linux 7 Virtualization Deployment and Administration Guide.
