One of the reasons for introducing virtio-gpu support to OvmfPkg and ArmVirtpkg was the fact that under KVM virtualization on ARM, the legacy VGA cannot be used reliably. This is due to an implementation detail of QEMU+KVM, which remaps cached host memory into the guest address space as a framebuffer behind a PCI BAR. Given that the purpose of a memory mapped framebuffer is its side effects, such BARs should never be mapped cacheable in the guest, and the mismatched attributes between host and guest result in a loss of coherency, visible as corruption in the framebuffer image. This issue does not occur under TCG emulation, nor did we expect it to actually bring down the guest under KVM, and so it was deemed harmless to keep support for the VGA device as well. However, as it turns out, the fact that the framebuffer BAR is mapped using device semantics by default may result in unalignment faults when we use the ordinary string copy routines on the contents. In theory, we could work around this by remapping the BAR as write combining, but it appears the generic PCI bus driver does not actually implement this. So let's remove the QemuVideoDxe driver altogether. This may result in loss of functionality for use cases that rely on the framebuffer to be directly addressable (such as EFIFB), but given that this never worked reliably under KVM in the first place, let's not let that stop us from dropping support for it.
