我安装了Arch（Antergos）来为KVM Vms启用PCI passtrough，但如果我启动VM它就会崩溃。我按照本教程。
我的硬件：
- 主板：Asrock H97M Pro4
- 处理器：英特尔®酷睿™i5-4690 CPU @ 3.50GHz×4
- GPU MSI GTX760 Twin Frozr
- 拉姆：16GB
- 操作系统：Antergos 64Bit
首先，我
- 在uefi中启用了VT-d
- 将intel_iommu =“on”添加到/ etc / default // grub中的GRUB_CMDLINE_LINUX_DEFAULT =“”
- 更新了grub

04:00.1 Audio device [0403]: NVIDIA Corporation GK104 HDMI Audio Controller [10de:0e0a] (rev a1)
所以我的GPU包括：
- VGA控制器：04：00.0（10de：1187）
- 音频控制器：04：00.1（10de：0e0a）
然后我创建了文件：/etc/modprobe.d/vfio.conf并写了
options vfio-pci ids=10de:1187,10de:0e0a
然后我创建了/etc/mkinitcpio.conf并附加到MODULES =“”
vfio vfio_iommu_type1 vfio_pci vfio_virqfd
重新启动我的机器并检查gpu是否有vfio驱动程序
lspci -k
04:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 760] (rev a1)
Subsystem: Micro-Star International Co., Ltd. [MSI] Device 2847

Kernel modules: nouveau
04:00.1 Audio device: NVIDIA Corporation GK104 HDMI Audio Controller (rev a1)
Subsystem: Micro-Star International Co., Ltd. [MSI] Device 2847
Kernel driver in use: vfio-pci
Kernel modules: snd_hda_intel
安装了一些包：
pacman -S qemu libvirt virt-manager
yaourt -S ovmf-git
编辑/etc/libvirt/qemu.conf
nvram = [
"/usr/share/ovmf/x64/ovmf_x64.bin:/usr/share/ovmf/x64/ovmf_vars_x64.bin"
]
启动/启用libvirt
systemctl enable --now libvirtd
systemctl enable virtlogd.socket
最后我创建了一个VM：
- 固件：UEFI
- CPU：选中“复制主机CPU配置”
- 插入Windows磁盘
现在它开始在虚拟控制台中，一切都很好！然后我添加了我的GPU（PCI设备）并再次启动它。现在它崩溃了，我不知道为什么！没有错误消息。
我希望你能帮助我，谢谢你的努力
