It will be a VM or BM, but I don't think accelerators should be tied
to the life of a single instance if that isn't technically necessary
(i.e., they are hot-pluggable devices). I can see plenty of scope for
use-cases where Cyborg is managing devices that are accessible to
compute infrastructure via network/fabric (e.g. rCUDA or dedicated
PCIe fabric). And even in the simple pci passthrough case (vfio or
mdev) it isn't hard to imagine use-cases for workloads that only need
an accelerator sometimes.
