Hi,
I’m an openstack developer trying to use
Assignment from a pool of SRIOV VFs in a libvirt <network> definition
from this link http://wiki.libvirt.org/page/Networking
My question is is it possible for nova (the openstack compute) to know
which VF out of the pool will be allocated to a VM before it invokes
libvirt to launch it?
In general no. Even though currently libvirt chooses the first free VF,
this is not a part of API, and thus it's not written into a stone. I
wouldn't rely on it. But the fact, you need this kind of information
makes me wonder why. What's your use case?
