In the meantime, by applying various solutions, the "Invalid PCI ROM header signature" error has been resolved, but the "can't change power state from D0 to D3hot" error still remains, and the VM cannot turn on normally. As you replied, the Rom-Bar option and the GPU PCI option...
VFIO是一种用于Linux操作系统的设备直通技术,它允许将物理设备(如GPU、PCI设备等)直接映射到虚拟机或容器中,从而实现高性能的硬件访问和裸金属云服务器的构建。VFIO提供了一套用户态接口和内核驱动,使得用户可以对设备进行完全控制和管理,并且可以绕过虚拟化层次的性能瓶颈,实现更低的延迟和更高的吞吐量。这使得VFIO成...
