Please note Red Hat's policy on Production Phase 3, which normally starts at the 7 year point.
In that phase, only those security updates deemed crucial are released in this phase. It is recommended that you plan to upgrade before this point whenever possible. New iao New major and minor releases are available about 2 to 6 weeks after upstream Red Hat publishes the SRPMs source packages of their product.
This time is needed to rebuild, validate, test QAtranslate and integrate new artwork. Although we understand that some of our users are excited about a new upcoming release, we ask you to be patient or help out in the release process. Once a 7. point release is issued say: 6.
After a transition interval of a few weeks, the old point version binaries are moved to the vault. There is a longer discussion at item 15 in the FAQ for more details.

For more information on what virtualization is, see the Red Hat Customer Portal. Using virtual machines VMs has the following benefits in comparison to using physical machines:. Flexible and fine-grained allocation of resources. A VM runs on a host machine, which is usually physical, and physical hardware can also be assigned for the guest OS to use.
However, the allocation of physical resources to the VM is done on the software level, and is therefore very flexible. A VM uses a configurable fraction of the host memory, CPUs, or storage space, and that configuration can specify very fine-grained resource requests. For example, what the guest OS sees as its disk can be represented as a file on the host file system, and the size of that disk is less constrained than the available sizes for physical disks.
Software-controlled configurations. The entire configuration of a VM is saved as data on the host, and is under software control. Therefore, a VM can easily be created, removed, cloned, migrated, operated remotely, or connected to remote storage. Separation from the host.

A guest OS runs on a virtualized kernel, separate from the host OS. This means that any OS can be installed on a VM, and even if the guest OS becomes unstable or is compromised, the host is not affected in any way. Space and cost efficiency. A single physical machine can host a large number of VMs. Therefore, it avoids the need for multiple physical machines to do the same tasks, and thus lowers the space, power, and maintenance requirements associated with physical hardware.
Software compatibility. Because a VM can use a different OS than its host, virtualization makes it possible to run applications that were not originally released for your host OS. For details, see Jso The basis of creating virtual machines VMs in RHEL 8 is the hypervisora software layer that controls hardware and enables running multiple operating systems on a host machine.
Chapter 1. Introducing virtualization in RHEL Red Hat Enterprise Linux 8 | Red Hat Customer Portal
The hypervisor includes the Kernel-based Virtual Machine KVM module and virtualization kernel drivers, such as virtio and vfio. These components ensure that the Linux kernel on the host machine provides resources for virtualization to user-space software. At the user-space level, the QEMU emulator simulates a complete virtualized hardware platform that the guest operating system can run in, and manages how resources are allocated on the host and presented to the guest.
In addition, the libvirt software suite serves as a hrel and communication layer, making QEMU easier to interact with, enforcing security rules, and providing a number of additional tools for configuring and running VMs. The configuration includes:.

For more information on the contents of an XML configuration, see Section 6. Downlozd hypervisor also makes the VM process accessible to the host-based interfaces, such as the virshvirt-installand guestfish utilities, or the web console GUI. When these virtualization tools are used, libvirt translates their input into instructions for QEMU.
QEMU communicates the instructions to KVM, which ensures that the kernel appropriately assigns the resources necessary to carry out the instructions. For more information on the host-based interfaces, see Section 1. For example:.
For instructions on basic virtualization management with the web console, see Chapter 5, Managing virtual machines in the web console. Although still supported in RHEL 8, virt-manager has been deprecated. The web console is intended to become its replacement in a subsequent release.
