[ovirt-users] Re: vGPU with NVIDIA M60 mdev_type not showing

2019-01-16 Thread Josep Manel Andrés Moscardó 

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.

How about kernel command line (cat /proc/cmdline)?  It's important to
have intel_iommu=on there (assuming an Intel machine).

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.


The hook is no longer needed nor should be installed.

Milan

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.

Nothing to do

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.
