[libvirt] [PATCH] Add support for Midonet virtual ports
by Antoni Segura Puimedon 17 Mar '15

17 Mar '15

Up until now, to plug VMs into the Midonet virtual networks it was necessary to use the 'last resort' 'ethernet' type. That implied having the domain tainted and having to deal witht the tap lifecycle outside of libvirt/VM lifecycle. With the patch I submit, a new virtualport type will be accepted by libvirt that will always require an interfaceid (as it is essential for binding a tap device to a virtual port that the virtual port itself exists and has a UUID). With that interfaceid, libvirt will delegate the binding on the Midonet userspace tools.

[libvirt] [PATCH] qemu: Check for negative port values in network drive configuration
by Erik Skultety 16 Mar '15

16 Mar '15

We interpret port values as signed int (convert them from char *), so if a negative value is provided in network disk's configuration, we accept it as valid, however there's an 'unknown cause' error raised later. This error is only accidental because we return the port value in the return code. This patch adds just a minor tweak to the already existing check so we reject negative values the same way as we reject non-numerical strings.

[libvirt] [RFC PATCH v2 0/4] Enable spapr-pci-vfio-host-bridge controllers for VFIO passthrough support
by Shivaprasad G Bhat 09 Mar '15

09 Mar '15

The following series of patches enable spapr-pci-vfio-host-bridge controllers on PPC64-pseries machine which is required for supporting host device passthrough using VFIO. There were some initial enablement work on the same at http://www.redhat.com/archives/libvir-list/2013-September/msg00838.html. On pseries(ppc64), the vfio host devices(will refer as hostdevs here on) cannot be assigned to the default emulated pci-host-bus(phb) controller(like the default pci.0). The hostdevs goto spapr-pci-vfio-host-bridge. The hostdevs belonging to the same iommu group share the same spapr-pci-vfio-host-bridge. Henceforth, new spapr-pci-host-bridge needs to be added for every hostdev belonging to any new iommu group. The hostdevs should be attached to their respective spapr-pci-vfio-host-bridge. Libvirt today adds all the devices to the default pci domain. The patch series take care to add the new controller. A new pci domain in the guest per controller is created. The hostdevs get their pci address in the respective domain. The patch series taskes care of device addressing in vfio hostdevs, SR-IOV interfaces and network interfaces from SRIOV virtual function pools.
