Hi all, I have a test GPU system that seemed to be working properly under Kilo running 1 and 2 GPU instnace types on an 8GPU server.
After Mitaka upgrade it seems to alway try and assing the same Device which is alredy in use rather than pick one of the 5 currently available. Build of instance 9542cc63-793c-440e-9a57-cc06eb401839 was re-scheduled: Requested operation is not valid: PCI device 0000:09:00.0 is in use by driver QEMU, domain instance-000abefa _do_build_and_run_instance /usr/lib/python2.7/dist-packages/nova/compute/manager.py:1945 it tries to schedule 5 times, but each time uses the same busy device. Since there are currently 3 in use if it had just picked a new one each time In trying to debug this I realize I have no idea how devices are selected. Does OpenStack track which PCI devices are claimed or is that a libvirt function and in either case where woudl I look to find out what it thinks the current state is?
