With this enhancement, the RHEL web console now supports the installation of RHEL virtual machines (VMs) using the default Download an OS workflow. As a result, you can download and install the RHEL OS as a VM directly within the web console.
The mdevctl tool now provides a new ap-check support utility. You can use mdevctl to persistently configure cryptographic adapters and domains that are allowed for pass-through usage into virtual machines as well as the matrix and vfio-ap devices. With mdevctl, you do not have to reconfigure these adapters, domains, and devices after every IPL. In addition, mdevctl prevents the distributor from inventing other ways to reconfigure them.
The q35 machine type does not support transitional virtio 1.0 devices, and RHEL 8 therefore lacks support for features that were deprecated in virtio 1.0. In particular, it is not possible on a RHEL 8 host to send SCSI commands from virtio-blk devices. As a consequence, attaching a physical disk as a LUN device to a virtual machine fails when using the virtio-blk controller.
After modifying a virtual machine (VM) disk image using the virt-customize utility, the guestfs-firstboot service in some cases fails due to incorrect SELinux permissions. This causes a variety of problems during VM startup, such as failing user creation or system registration.
Currently, when booting a RHEL 8 virtual machine (VM) on the Hyper-V hypervisor, the host portion of the Host, Bus, Target, Lun (HBTL) SCSI address in some cases changes. As a consequence, automated tasks set up with the HBTL SCSI identification or device node in the VM do not work consistently. This occurs if the VM has more than one disk or if the disks have different sizes.
As these values are specific for each virtual disk, the configuration needs to be done for each VM instance. It may, therefore, be useful to use the %include syntax to place the disk information into a separate file. 153554b96e
