I bought a LSI-9211-8i / SAS 2008 controller which reports support for
SR-IOV in lspci and I am wondering how I can use it.
There is no info on the internet about this not even for their newer
controllers where there is a lot of advertising about SR-IOV.
The idea is that you can assign a RAID array, individual hard drive, etc to
a VF which is then assigned to a VM via IOMMU providing better almost native
performance vs emulated disks.
Thanks!
If it supports SR-IOV you can pass it to a guest with VFIO. If it did
not support SR-IOV it would not support VFIO.
I know - my question is how do I create the virtual functions and assign
the drives to them instead of simply attaching the entire controller?
According to LSI's press release you could have for instance 5 different
RAID's assigned to 5 different VM's via virtual functions - not simply
all of them assign to one VM via assigning the controller like a non
SR-IOV device
