Hi all,
I have a host with 2 M60 with the latest supported driver installed, and
working as you can see:
root@esxh-03 vdsm]# lsmod | grep vfio

But the issue is that when I do :
# vdsm-client Host hostdevListByCaps
I don't see any "mdev" device. Also the directory /sys/class/mdev_bus
is not existing.
Am I missing something ?
Cheers.

Hi,
I am using CentOS 7.6 and the latest oVirt release. Is it possible that
the package vdsm-hook-vfio-mdev is needed? As far as I understand it is
already deprecated, but I cannot find anything on the documentation.
[root@esxh-03 ~]# yum install vdsm-hook-vfio-mdev
Loaded plugins: enabled_repos_upload, fastestmirror, package_upload,
product-id, search-disabled-repos,
: subscription-manager, vdsmupgrade
This system is not registered with an entitlement server. You can use
subscription-manager to register.

* extras: mirror2.hs-esslingen.de
* ovirt-4.2: ftp.plusline.net
* ovirt-4.2-epel: ftp-stud.hs-esslingen.de
* updates: ftp.fau.de
Package vdsm-hook-vfio-mdev-4.20.35-1.el7.noarch is obsoleted by
vdsm-4.20.43-1.el7.x86_64 which is already installed
Nothing to do

Hi Milan,
I have re-deployed the server and now is booting with:
[root@esxh-03 ~]# cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-3.10.0-957.1.3.el7.x86_64
root=/dev/mapper/centos_esxh--03-root ro nofb splash=quiet
crashkernel=auto rd.lvm.lv=centos_esxh-03/root
rd.lvm.lv=centos_esxh-03/swap rhgb quiet nouveau.modeset=0 intel_iommu=on
But still not able to see mdev:
[root@esxh-03 ~]# vdsm-client Host hostdevListByCaps | grep -i mdev
[root@esxh-03 ~]#
Do you have any other idea about what could be going on?
Cheers.

New subject: [SOLVED] Re: vGPU with NVIDIA M60 mdev_type not showing
Hi,
I found what was going on, so as Milan stated, the order is:
- Enable intel_iommu=on
- Reinstall the host
- Install NVIDIA driver
I had the nvidia driver installed before enabling iommu in the kernel....
Cheers.
