I have the answer.
I had to change my lines from:
-device
vfio-pci,host=0c:00.0,bus=root_port1,addr=00.0,multifunction=on,x-vga=on \
-device vfio-pci,host=0c:00.1,bus=root_port2,addr=00.1,multifunction=on \
-device vfio-pci,host=0d:00.0,bus=root_port3,addr=01.0,multifunction=on \
to:
-device
vfio-pci,host=0c:00.0,bus=root_port1,addr=00.0,multifunction=on,x-vga=on \
-device vfio-pci,host=0c:00.1,bus=root_port2,addr=00.0,multifunction=on \
-device vfio-pci,host=0d:00.0,bus=root_port3,addr=00.0,multifunction=on \
Apparently, this is a known bug.
All cards must be on the same addr.
I have both gpus and 8gb of vmem instead of just 4gb.
Nice to know you CAN have more than one video card with gpu passthrough.

The card has 4gb per gpu.
So 8gb of hbm memory.

ok,
third try to get a new thread
Anyway,
I tried your global switch.
I still get code 10 device failed to start on the 2nd gpu.
I tried 8GB.
Am I actually allocating 8GB for the pci hole or is that just a size?
I did a full reinstall and factory reset on the video driver.
AFAICT you've got 32GB between these GPUs, that would probably be the
minimum I'd try, maybe even 64GB.

Use:
