You're welcome! My machine learning team members that I am maintaining oVirt for tend to load training data is large sequential batches, which means bandwidth is nice to have. While I give them local SSD storage on the compute nodes, I also give them lots of HDD/VDO based gluster file space,

My apologies for duplicating posts - they initially got stuck and I really wanted to reach out to the group with the query to try and discover unknowns. Passing through the whole pci nvme device is fine, because the VM is locked to the host due to the gpu pci pass through anyway. I will implement

You gave some different details in your other post, but here you mention use of GPU pass through. Any pass through will lose you the live migration ability, but unfortunately with GPUs, that's just how it is these days: while those could in theory be moved when the GPUs were identical (because
