I used PVE+A16(64G)+256G memory and allocated 10 virtual machines, one of which was allocated 4G video memory. When the virtual machine is started, 3-5 virtual machines can be started normally, and after a few hours, other virtual machines cannot be started. Error [NVIDIA-vgpu-vfio] no vgpu device found for vf0000: 8b: 01.7. [228095.276939] [NVIDIA-vgpu-vfio] current _ vgpu _ type of vfnot configured, if the graphics card allocated by the virtual machine is removed, it can be started normally, but my memory 64G has not been fully allocated. If the PVE server is restarted, it is ok to start all virtual machines immediately after the restart. If one machine is not started, it will not start after a few hours. I really don't understand. Help me.
The VPUG virtual machine of A16 cannot be started.

Hi, it looks like your Virtual Function (VF) for vGPU passthrough is not properly bound to VFIO at the time the VM starts.
Your VF (0000:8c:02.2) belongs to IOMMU group 221, but that group is not attached to VFIO yet.
Run:
and see what driver is bound.
If it’s not vfio-pci, rebind it manually:
(Replace 10de 2237 with your actual vendor:device ID from lspci -nn.)
See if it works.

echo "10de 2237" > /sys/bus/pci/drivers/vfio-pci/new_idSee if it works.
It's all NVIDIA
I executed two orders, but it still didn't work.
