Description Miroslav Rezanina 2016-11-07 08:36:23 UTC

Disable new devices introduced with rebase to QEMU 2.7:

- qemu,register
- vfio-pci-igd-lpc-bridge

Comment 1 Miroslav Rezanina 2017-01-23 09:22:25 UTC

We rebased to 2.8 instead of 2.7 so we need to remove devices added in 2.8 too.

List of new devices:

- floppy
- vhost-vsock-device
- vhost-vsock-pci
- virtio-crypto-device
- virtio-crypto-pci
- amd-iommu
- AMDVI-PCI
- loader
- or-irq

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.

Comment 2 Miroslav Rezanina 2017-02-20 10:06:36 UTC

Fix included in qemu-kvm-rhev-2.8.0-5.el7

Comment 4 Chao Yang 2017-06-01 09:35:49 UTC

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 ? 

on qemu-kvm-rhev-2.8.0-3.el7.x86_64 

Storage devices:
name "floppy", bus floppy-bus, desc "virtual floppy drive"

Network devices:
name "virtio-crypto-device", bus virtio-bus
name "virtio-crypto-pci", bus PCI

Uncategorized devices:
name "amd-iommu", bus System
name "AMDVI-PCI", bus PCI
name "loader", desc "Generic Loader"
name "or-irq"
name "qemu,register"
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. 





Setting VERIFIED.
