Comment 6 for bug 1616442

Say you have an SR-IOV card that is being used for both physical function and virtual function allocation. While there is nothing allocated (PF or VF) or has a VF in use, all should be well with the agent. While it doesn't care about PFs, it will care about the VFs. When an allocation of the PF succeeds (i.e. the VM consumes it), won't the VFs also disappear? If so can the agent handle it?

I agree that the VFs being 0 are less of an issue really since the either the device isn't there (the PF is allocated), it has VFs or it isn't supposed to have VFs and the agent shouldn't "care" about it since that agent isn't responsible for PFs.
