Disable new devices introduced with rebase to QEMU 2.7:
We rebased to 2.8 instead of 2.7 so we need to remove devices added in 2.8 too.
List of new devices:
vhost-vsock-device (and vhost-vsock-pci) are requested by bz #1291284.
floppy device is qomified floppy device, we want to keep the functionality without allowing command-line access.
Fix included in qemu-kvm-rhev-2.8.0-5.el7
Steps to verify this bug:
1. re-compile source code and compare build log on unfixed and fixed version
or-irq.o, generic-loader.o, amd_iommu.o, virtio-crypto-pci.o, register.o was observed on qemu-kvm-rhev-2.8.0-3.el7.x86_64 but on qemu-kvm-rhev-2.9.0-7.el7 otherwise.
2. check output of -device ?
name "floppy", bus floppy-bus, desc "virtual floppy drive"
name "virtio-crypto-device", bus virtio-bus
name "virtio-crypto-pci", bus PCI
name "amd-iommu", bus System
name "AMDVI-PCI", bus PCI
name "loader", desc "Generic Loader"
name "vfio-pci-igd-lpc-bridge", bus PCI, desc "VFIO dummy ISA/LPC bridge for IGD assignment"
on qemu-kvm-rhev-2.9.0-7.el7, neither of above was observed.
