Commit 7c8e606b64c73ca56d7134cb16d01257f39c53ef attempted to fix
the specification of the ramfb property for vfio-pci devices, but it
failed when ramfb is explicitly set to 'off'. This is because only the
'vfio-pci-nohotplug' device supports the 'ramfb' property. Since we use
the base 'vfio-pci' device unless ramfb is enabled, attempting to set
the 'ramfb' parameter to 'off' this will result in an error like the
following:
error: internal error: QEMU unexpectedly closed the monitor
(vm='rhel'): 2024-06-06T04:43:22.896795Z qemu-kvm: -device
{"driver":"vfio-pci","host":"0000:b1:00.4","id":"hostdev0","display":"on
","ramfb":false,"bus":"pci.7","addr":"0x0"}: Property 'vfio-pci.ramfb'
not found.
This also more closely matches what is done for mdev devices.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
