This driver is only available if a virtio disk is configured. Right-click on the device whose driver you wish to update, and select Update Driver From the drop-down menu, select Update Driver Software The first page of the driver update wizard asks how you want to search for driver software. Click on the second option, Browse my computer for driver software.
A separate driver is provided for each of the various combinations of operating system and architecture. Once you have navigated to the correct location, click OK. Click Close to close the installer. Installing Virtualization Packages Manually. To use virtualization on Red Hat Enterprise Linux, at minimum, you need to install the following packages:. The qemu-img package is installed as a dependency of the qemu-kvm package.
Several additional virtualization management packages are also available and are recommended when using virtualization:. This is a graphical tool for administering virtual machines.
If you chose to import an existing disk image during the first step, virt-manager will skip this step. Assign sufficient space for your virtual machine and any applications it requires, then click Forward to continue.
Verify the settings of the virtual machine and click Finish when you are satisfied; doing so will create the virtual machine with default networking settings, virtualization type, and architecture.
If you prefer to further configure the virtual machine's hardware first, check the Customize configuration before install box first before clicking Finish. Doing so will open another wizard that will allow you to add, remove, and configure the virtual machine's hardware settings.
After configuring the virtual machine's hardware, click Apply. After the installation completes, you can connect to the guest operating system. Next, configure the OS type and Version of the installation. Ensure that you select the appropriate operating system type for your virtual machine.
This can be specified manually or by selecting the Automatically detect operating system based on install media check box. The wizard shows the number of CPUs and amount of memory you can allocate; these values affect the host's and guest's performance.
Virtual machines require sufficient physical memory RAM to run efficiently and effectively. Assign sufficient virtual CPUs for the virtual machine. If the virtual machine runs a multi-threaded application, assign the number of virtual CPUs the guest virtual machine will require to run efficiently. You cannot assign more virtual CPUs than there are physical processors or hyper-threads available on the host system.
After you have configured the memory and CPU settings, click Forward to continue. Memory and virtual CPUs can be overcommitted. Enable and assign sufficient space for your virtual machine and any applications it requires. Assign at least 5 GB for a desktop installation or at least 1 GB for a minimal installation. Live and offline migrations require virtual machines to be installed on shared network storage.
For information on setting up shared storage for virtual machines, see Section Enter the size of the disk image to be created. If the Allocate entire disk now check box is selected, a disk image of the size specified will be created immediately. If not, the disk image will grow as it becomes filled.
