This bug was related to incompatibilities between dkms provided by the Mellanox OFED - implementing some new netlink protocol addons - and Ubuntu kernel. This type of issues have already been addressed between Canonical and Mellanox (but might occur again while Mellanox OFED is using for RDMA and IB related setups). ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1496942 Title: Infiniband (mellanox) SR-IOV and libvirt + libnl problems Status in linux package in Ubuntu: Incomplete Status in linux package in Debian: New Bug description: When trying to start an IB SR-IOV guest by using the following XML: following the Mellanox SR-IOV guide, we are able to start guests using kernel 3.16 (Utopic).
