PVE9直通板载SATA控制器出错

deergula

想把SATA盘直通给飞牛用，直通后飞牛无法启动。报错：

error writing '1' to '/sys/bus/pci/devices/0000:2b:00.0/reset': Inappropriate ioctl for device
failed to reset PCI device '0000:2b:00.0', but trying to continue as not all devices need a reset
kvm: -device vfio-pci,host=0000:41:00.4,id=hostpci1,bus=pci.0,addr=0x11: warning: vfio 0000:41:00.4: Could not enable error recovery for the device
kvm: ../hw/pci/pci.c:1803: pci_irq_handler: Assertion `0 <= irq_num && irq_num < PCI_NUM_PINS' failed.
TASK ERROR: start failed: QEMU exited with code 1
主板是华硕的WS-WRX80E用命令查看有三个SATA控制器，前两个直通给飞牛进入后无硬盘。PVE中还能看到硬盘，后面一个无法启动飞牛但硬盘在PVE中看不到了。（注：系统是装在M2上的与SATA盘无关）
28:00.0 SATA controller: ASMedia Technology Inc. ASM1061/ASM1062 Serial ATA Controller (rev 02)
29:00.0 SATA controller: ASMedia Technology Inc. ASM1061/ASM1062 Serial ATA Controller (rev 02)
2b:00.0 SATA controller: Advanced Micro Devices, Inc. [AMD] FCH SATA Controller [AHCI mode] (rev 51)
望大佬能指点，谢谢了！

主板的PCIe热插拔开关换个状态试试？开的就关，关的就开

1. 把"blacklist ahci"加到/etc/modprobe.d/blacklist.conf
2. 在/etc/modprobe.d/vfio.conf中加入下面字段：
options vfio-pci ids={SATA控制器ID}
softdep ahci pre: vfio-pci
3. 直通时关闭ROM-BAR

PVE9的6.14内核直通sata控制器很容易出问题，我直通ASM1166后启动虚拟机会卡死，关闭了ROM-BAR才解决
