Description of problem: oVirt Node needs to support vdsm configuring network devices that support SR-IOV. So we need to figure out what needs to be included on the node, and what kernel command line options we need to pass to enable this functionality for vdsm
Antoni, can you tell if Node provides everything what is needed for SR-IOV?
<apuimedo> fabiand: you must make sure in the node that the driver is loaded with virtual functions specified <apuimedo> that's one point <apuimedo> usually in /etc/modprobe.d/ <fabiand> apuimedo, what drive ris it? <apuimedo> it depends <fabiand> :) <apuimedo> the most typical is the igb for intel cards <apuimedo> vt-d should be enabled in the machine, of course <apuimedo> and the kernel command line should have intel_iommu=on (at least for intel cards) <apuimedo> (sometimes it is needed to pass iommu=force as well)
The igb and ixgb modules need to be loaded correctly.
<apuimedo> it seems cxgb4 also supports it <apuimedo> and bnx2x too (broadcom)
fabian, ixgbe, ixgb is PCI and doesn't support this IIRC, ixgbe is the PCI-xpress and supports it.
