Adding whitelist into nvme.conf was not sufficient.

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 Best regards, Tom Nabarro BEng (hons) Extreme Storage Architecture & Development Intel Corporation E: tom.nabarro(a)intel.com M: +44 (0)7786 260986 Skype: tom.nabarro --------------------------------------------------------------------- Intel Corporation (UK) Limited Registered No. 1134945 (England) Registered Office: Pipers Way, Swindon SN3 1RJ VAT No: 860 2173 47 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).
