USB3 redirection
by Rik Theys
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?
Regards,
Rik

New ovirt 4.4.10 user unable to login
by louisb＠ameritech.net
I just create an new user in ovirt 4.4.10 using the tool "ovirt-aaa-jdbc-tool". I'm unable to log into ovirt using the newly created user. I'm getting the error message: The user xyzabcs@internal-authz with profile [internal] is not authorized to perform login.
Is the profile the same as a "Group", I've also tried creating a new group also asl follows: sudo ovirt-aaa-jdbc-tool group-manage groupadd --group='Administrator'. I get the following message:
Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false

Add a group as a member to group-name.
Options:

by Nyika Csaba
Hi,
I have an ovirt cluster (4 nodes) and a stand-alone engine.
Last week one of the cluster-members node went to "Non-responsive" status, because i forgot to renew the host certificate.
On this node's vms now are in "unknown" states. (but running)
How can i stop this vms and how can i start them on another nodes?
thanks

OVN routing and firewalling in oVirt
by Gianluca Cecchi
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
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
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...) 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!

Storage domain out of space need help
by louisbohm＠gmail.com
Running Oracle VM (Ovirt 4.3) on Oracle Linux 7.8.
Storage Domain (comprised of local disks in RAID10) is out of space. We have 2 VMs on this physical host. One of them is up (the important one). One of them is down. The VM that is down is a test VM and if there is a way I can delete it from the disk and recover the disk space.
I can also purchase more physical disks and add them to the system but then how do I grow the Storage domain if its state is INACTIVE? I also have a second physical server running Linux acting as a NFS server. I would happily add the NFS space to this Storage domain and move the TEST vm to the NFS space.
Can some one help explain how I can fix this with out destroying the currently working VM? I have created a backup of the data on the VM but it would be very painful if I had to rebuild it.
Thanks,

Confused Newby - RHEL 9.0Beta
by Trevor Monaghan
Hello Friends at oVirt,
I set up a MINI PC as to host with the modest aim of hosting a couple of VMs.
I mainly decided on Red Hat for its easy of use when setting up RAID1 with a pair of NVme SSDs.
vSphere does not support RAID
Ubuntu the option of setting up RAID is not available or hard to locate even after Googling into for hours...
Never mind, now set up with RHEL 9.0Beta I was not able also to learn if it requires upgrading to RHV 4.4
Then I came across oVirt and became confused between both with Cokpit that is also mentioning that Ovirt can be an addon.
At the moment RHEL 9.0Beta works fine and could do without breaking the system.
Is there a need to upgrade it to RHV 4.4? As the existing Virtualisaton of RHEL 9.0Beta is rather light or perhaps I need oVirt to access its full potentional?
What confuses me is that Red Hat indicates RHV 4.4 to be a great enterprise solution however based on the features available to me when Cokpit is used is rather contradictory when compared to other technologies available even for free.
It could be amazing to hear from you,
Wish you well,
Trevor

Hello,
I’m used to having a nested-ESXi on another ESXi, but we are testing Ovirt these days, and we are facing a strange behavior with the engine VM. I have a hyper-converged Ovirt cluster with a hosted-engine, and whenever I reboot/shutdown one of the nodes for testing (a node that is not hosting the engine VM of course) the engine goes crazy and too slow, and starts losing network connecting to the remaining (healthy) nodes in the cluster, and I can hardly SSH into it. Ping also has too many drops while another node is down. Once that faulty node is up again the engine works very fine, but this is really limiting my ability to make further Ovirt HA tests before moving to production. I though maybe the promiscuous mode on the physical host causes this, but never faced this with nester-virtualization with VMware, and turning-off promiscuous mode isn’t an option either… what do you think please?
