Subject Re: Exposing PCIe capabilities to the Cloud Scheduler
Date Fri, 14 Feb 2014 06:21:27 GMT
I'd expect it to be something service-offering based, e.g. if your
offering specifies GPU, it auto-allocates from detected GPU elements,
if it's 10G nic, it auto allocates from that. Admin would still have
to tag the host as being capable, somehow, but it would alleviate the
manual registration of every PCI ID for every VF in every
agent.properties, for example. One could simply turn on SR-IOV NIC or
GPU.
