Tesla P4 and /sys/class/mdev_bus/
by Fabrice Bacchella 13 Nov '19

13 Nov '19

I have a Tesla P4 installed on a HPE ProLiant DL360 Gen10 on a CentOS 7.7. The setup was running fine since at least February. I made a successful upgrade from oVirt 4.2 to 4.3 and CentOS 7.6 to CentOS 7.7. I was using in oVirt in a pass-througth setting. I made a minor upgrade a few days ago. And since the VM is unable to see the Tesla P4. I think that the main problem is with mdev. vdsm-client Host hostdevListByCaps | grep mdev return nothing. There is no directory /sys/class/mdev_bus. I tried a full modload: modprobe nvidia_vgpu_vfio nvidia vfio_mdev mdev vfio_iommu_type1 vfio nvidia nvidia-modeset nvidia-drm nvidia-uvm vfio-pci. But it does nothing. Why did my kernel think the P4 is not mdev-compatible any more ? How can I check that ? I think it break when upgrading my kernel from kernel-3.10.0-1062.1.2.el7.x86_64 to kernel-3.10.0-1062.4.1.el7.x86_64. I tried with both the nouveau driver and the nvidia driver.

Re: Do I need to use self hosted engine with a GlusterFs three node setup
by Strahil 13 Nov '19

I remember creating my oVirt setup in 2 stages: 1. Using cockpit to deploy the gluster cluster 2. Using cockpit to deploy HCI on the created gluster clustet. If that's not changed you can only deploy the gluster clustet, thrn deploy the engine somewhere else and then connect the engine (add storage domain) to the gluster cluster, which also can be your oVirt compute nodes (making them at the end HyperConverged oVirt Cluster). Of course , that was an year ago - so it could be different.

Is it a case that we need to configure the hosts to use gluster storage with the cli commands prior to adding it to a pre-existing non hosted engine? > > Donagh > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org > Privacy Statement: https://www.ovirt.org/site/privacy-policy/ > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/IIEY3Z3GDGH4V…

You don't need to host the engine on the gluster cluster. I know people you have hosted the engine on a bare metal (pacemaker cluster) , so feel free to experiment. The only requirement is that tge engine needs to be able to communicate with the hosts (I'm not sure if layer 2 connectivity is necessary).

External networks issue after upgrading to 4.3.6
by ada per 13 Nov '19

13 Nov '19

After upgrading to the latest stable version the external networks lost all functionality. Under providers-->ovn-network-provider the test runs successfully. But when im creating an external provider network, attaching it to a router as a LAN setting up dhcp lease it is not reachable from other VMs in the same network. Hosts and hosted engine can't seem to ping it either. I tried disabling firewalls on both hosted engines, VMs and host and still nothing. When configuring Logical networks or VLANs they work perfectly tje one problem is the external networks. I have another environment running on a previous version of ovirt and it works perfectly there. I think its a bug. Thanks for your help

Re: Migrate VM from oVirt to oVirt
by Strahil 12 Nov '19

12 Nov '19

You will need a storage that will be your 'USB stick' . For example you can attach NFS-based storage domain, migrate the disks of the VM to that storage. Then power off that VM, set the storage to maintenance and then detach it from first oVirt engine. Then you attach and activate that NFS storage in your new oVirt engine. After Activation, there will be an 'Import VMs/templates' tab . Click on it and import the VM in a cluster. Last step is to migrate your VM's disks from that NFS to their permanent storage.

Hi All, Does ovirt support sshfs for mount locally accessible LUN's instead of NFS? -- Thx, TK.
