Dup of bug 431454 ? Hi Yaniv, no, as Bug 431454 discusses a LUN passthrough with a NPV adapter being created on the hypervisor, whereas this RFE is for NPV adapter passthrough, so not a single LUN, but as discussed in Bug 431454 a complete NPV adapter. It was asked in https://bugzilla.redhat.com/show_bug.cgi?id=431454#c92 to create a separate RFE for this. Cheers, Martin (In reply to Martin Tessun from comment #4) > Hi Yaniv, > > no, as Bug 431454 discusses a LUN passthrough with a NPV adapter being > created on the hypervisor, whereas this RFE is for NPV adapter passthrough, > so not a single LUN, but as discussed in Bug 431454 a complete NPV adapter. > > It was asked in https://bugzilla.redhat.com/show_bug.cgi?id=431454#c92 to > create a separate RFE for this.

Yes, it does not work that way, as it is a virtual device, and PCI passthrough is not able to address this device. > > > > Cheers, > > Martin Martin, I tried to understand the various NPIV related bugs...there are a bit too many around:) But IIUC this is what bug 1270581 was about. The only thing which is not there is the actual creation of vHBA, that needs to be done separately on host. But once it is there it will be seen in the hostdev UI and can be passed through as a scsi adapter into a VM Can you confirm? Hi Michal, Afaik thios will not work (yet) as qemu-kvm is missing this feature. See BZ #834514 for some more details. But as soon as this is sorted, indeed, it will probably work this way. Cheers, Martin (In reply to Martin Tessun from comment #0) Hi Martin, As this bz description contains the business justification for this project, can this be opened to our FC HBA vendors for them to evaluate, or would you prefer to present to them directly?

Cheers, Martin As the Storage Vendors do not want to follow up on NPIV any more but instead are working on new solutions, we cannot get this feature done anymore, as we are missing basic enablement from the HBA vendors here. |
