直通4070TIS internal error: Unknown PCI header type '127' for device '0000:02:00.0'

Featured Replies

服务器配置:

ASUS Pro Art Z790

Intel 13900K

ASUS Pro Art 4070 Ti Super

问题出现过程:

4070 Ti Super 原来位于主板的第二个PCIE插槽,第一个PCIE插槽空着,由于最近要新上一张5090,所以想把4070TIS移至第一槽,移动后出现 直通4070TIS的Win11虚拟机无法启动,重启物理机后首次启动虚拟机 启动极其缓慢,但是可以启动成功,进入Windows后发现没有4070TIS,强制关闭虚拟机也很缓慢,并提示:Failed to terminate process 38790 with SIGKILL: Device or resource busy

关闭虚拟机后再次启动则报错:internal error: Unknown PCI header type '127' for device '0000:02:00.0'

0000:02:00.0为4070 Ti Super

以前讲4070 Ti Super由主板第一槽换至第二槽时也出现过此问题,但莫名其妙的好了,具体怎么好的记不清了

目前已尝试:

1.更新主板 BIOS 无效

2.重新拔插显卡 无效

3.重新安装UNRAID 最新版 无效

4.删除虚拟机配置文件 重建虚拟机 无效

5.删除VFIO配置文件 无效

经排查 BIOS中将第一个插槽中的PCIE 模式设置成了X8/X8,改为自动后恢复正常
