What does the ovirtmgmt service do & how do I work withit in regards to networking
by louisb＠ameritech.net 20 Apr '22

20 Apr '22

I've installed ovirt 4.4.10 several times and found myself not being able to reach out to the internet to perform updates to the OS or ovirt. When installing ovirt I've accepted the defaults and found that networking on my server has stopped working. I've also noticed that the ovirtmgmt service has taken over the network port/NIC that I've assigned in the DNS. My server has six/6 NIC's installed but after the install of ovirt with the defaults I'm unable to perform another network functions other than go to ovirt. How do i get ovirt to co-exist on the server as it relates to networking. I just have the OS & GUI installed and then ovirt. I've checked the firewall and not found anything out the ordinary. When this happens what can I do to get things back to normal, the ability to apply OS and ovirt updates? I'm going to install ovirt again making sure that I don't take the default regarding the firewall, maybe this will help? Thanks

NVIDIA vgpu mdev/mediated devices are getting deleted/removed after VM shutdown with ovirt

Hi Team, NVIDIA vgpu mdev/mediated devices are getting deleted/removed after VM shutdown with ovirt. How I can make them persistent even after VM shutdown/poweroff ? I want to set some vgpu parameter in file /sys/bus/mdev/devices/vgpu-id/nvidia/vgpu_params for testing to mdev. But can't do as uuid of mdev are not persistent. mdev are not there in /sys/bus/mdev/devices/ after VM shutdown. We were using RHV/Red Hat Virtualization Host 4.4.10 host with NVIDIA vGPU. virsh commands are helping. Can you please help?

USB3 redirection
by Rik Theys 19 Apr '22

19 Apr '22

Hi, I'm trying to assign a USB3 controller to a CentOS 7.4 VM in oVirt 4.1 with USB redirection enabled. I've created the following file in /etc/ovirt-engine/osinfo.conf.d: 01-usb.properties with content os.other.devices.usb.controller.value = nec-xhci and have restarted ovirt-engine. If I disable USB-support in the web interface for the VM, the xhci controller is added to the VM (I can see it in the qemu-kvm commandline), but usb redirection is not available. If I enable USB-support in the UI, no xhci controller is added (only 4 uhci controllers). Is there a way to make the controllers for usb redirection xhci controllers?

OVN routing and firewalling in oVirt
by Gianluca Cecchi 19 Apr '22

19 Apr '22

Hello, how do we manage routing between different OVN networks in oVirt? And between OVN networks and physical ones? Based on architecture read here: http://openvswitch.org/support/dist-docs/ovn-architecture.7.html I see terms for logical routers and gateway routers respectively but how to apply to oVirt configuration? Do I have to choose between setting up a specialized VM or a physical one: is it applicable/advisable to put on oVirt host itself the gateway functionality? Is there any security policy (like security groups in Openstack) to implement? Thanks, Gianluca

OVN in oVirt : practical use cases
by ravi k 17 Apr '22

17 Apr '22

Hello, I was exploring OVN in oVirt and got thinking as to where it's practical use cases are? Folks who've implemented it in their production environments, can you please explain how you are using OVN in your environment. It seemed to be a bit complex for implementing and maintaining. It might be complex to me because I'm still fairly new to it. So is the OVN/OVS implementation geared towards teams that build the backend functionalities for virtualization softwares like VMware NSX etc? Hence my question asking if there are any practical benefits to using OVN/OVS in a regular virtualization environment. For example, if we're a financial or automobile setup where we use oVirt for provisioning VMs, what extra value does OVN/OVS add if we were to use it. Regards, Ravi

Emulex OneConnect 10Gb NICs on Ovirt 4.4.10
by thkam＠hua.gr 16 Apr '22

16 Apr '22

Hi We have a large number of HP servers where we use Ovirt and we are having problems upgrading the nodes to Ovirt 4.4.10 More specifically the servers have the Emulex OneConnect 10Gb NICs and what we did in previous Ovirt node installations was to download the driver rpm (e.g. kmod-be2net-12.0.0.0-8.el8_5.elrepo.x86_64.rpm) and then install it using "rpm -ivh ... " and carrying out "modprobe be2net" For 4.18.0-365 we could not find a separate rpm but it looks like this was included in kernel-modules-4.18.0-365.el8.x86_64.rpm (https://centos.pkgs.org/8-stream/centos-baseos-x86_64/kernel-modules-4.18.0…) which is already installed. "modprobe be2net" produces no errors but the network interfaces do not show up in "ip -a" even after reboot. Are we missing something here, or is our infrastructure unusable with 4.4.10? Things were working for 4.4.9. Thanks!
