[ovirt-users] Mellanox OFED with oVirt

Hello, Anyone had success using Mellanox OFED with oVirt? Already learned some things: 1. I can’t use oVirt Node. 2. Mellanox OFED cannot be installed with mlnx-ofed-all since it breaks dnf. We need to rely on the upstream RDMA implementation. 3. The way to go is running: dnf install mlnx-ofed-dpdk-upstream-libs But after the installation I ended up with broken dnf: [root@c4140 ~]# dnf update Updating Subscription Management repositories.
