[SPDK] vfio multiple processes

Can't run multiple SPDK processes each accessing disjoint set of NVMe drives using VFIO driver (even as root). Each process seems to try to access all /dev/vfio/* device files and get lots of resource busy messages. Sometimes one of the processes complaint it can't find the device it's been assigned in nvme.conf.

Have any ideas?
(processes are started in normal, non-multiprocess mode)

Thanks in advance
