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.

(try to add '--allowerasing' to command line to replace conflicting packages or
'--skip-broken' to skip uninstallable packages or '--nobest' to use not
only best candidate packages)
That are the packages installed:
[root@c4140 ~]# rpm -qa *mlnx*
mlnx-dpdk-19.11.0-1.51066.x86_64
mlnx-ofa_kernel-devel-5.1-OFED.5.1.0.6.6.1.rhel8u2.x86_64
mlnx-ethtool-5.4-1.51066.x86_64
mlnx-dpdk-devel-19.11.0-1.51066.x86_64
mlnx-ofa_kernel-5.1-OFED.5.1.0.6.6.1.rhel8u2.x86_64

mlnx-iproute2-5.6.0-1.51066.x86_64
And finally this is the repo that I’m using:
[root@c4140 ~]# cat /etc/yum.repos.d/mellanox_mlnx_ofed.repo

# Mellanox Technologies Ltd. public repository configuration file.
