Hello, We're not using nodes but CentOS 7.x hosts. Do you know if some documentation has been written about the proper way to upgrade the operating system of the hosts, and especially how to prevent breaking dependencies or cause versions flaws? Thank you. -- Nicolas ECARNOT

USB host support?
by Hetz Ben Hamo 29 Jun '19

29 Jun '19

Hi, I'm in communication with a company that thinks about RHV. One of the requirements is USB host support (which will be on the nodes, not on the desktops). I haven't found any way to connect USB to a VM other then through SPICE, but this method won't help as these dongles won't be on desktops. Is this in the road map of oVirt? Thanks

I think raid is OK. At least my setup has a raid0 of 2 HDDs. In the error message there is the command that is being executed by the playbook.

yum versionlock in ovirt node 4.3
by markus.falb＠mafalb.at 28 Jun '19

28 Jun '19

Hi, I just upgraded some ovirt node 4.2.8 to ovirt node 4.3.4 After a ...snip # yum update ovirt-node-ng-image-update snap... I rebooted, and afterwards I wanted to run a yum update like I was doing it with the previous versions, but ...snip # yum update --disableplugin fastestmirror,subscription-manager Loaded plugins: enabled_repos_upload, imgbased-persist, package_upload, product-id, search-disabled-repos, vdsmupgrade, versionlock Repository centos-sclo-rh-release is listed more than once in the configuration Excluding 76 updates due to versionlock (use "yum versionlock status" to show them) No packages marked for update Uploading Enabled Repositories Report Cannot upload enabled repos report, is this client registered? snap... "Excluding 76 updates due to versionlock" ! Many packages are locked via the yum-versionlock plugin, also many system packages like the kernel and python (well, these 2 got my attention because there were security updates published recently). Isn't it recommended anymore to update the these packages to the latest versions? Do you use modified packages (different from CentOS?) Is it safe to remove the versionlock? Best regards, Markus

Re: Cannot inquire Lease

It looks OK to me , but I'm no expert in that. In such case you will have 5 GB as a reserve, which you can reduce, just to be able to delete some data (in this case VM). The question that comes to my mind is - did you receive any warning by oVirt that gluster is almost full ?

Hm ... Removing it from the gluster but not inside oVirt can cause a lot of headaches. Can you find that image in oVirt Storage -> Disks Sadly , you got no other option and the optimal approach would be to take the deletion from oVirt UI/API before the storage gets full. Ovirt has the option to notify you in advance.

VM IPsec network performance
by TranceWorldLogic . 27 Jun '19

27 Jun '19

Hi, I have enable multi-queue feature on nic card and I am getting normal throughput as 26 Gbps. But when I am trying throughput test with IPsec I am getting only max 1.5Gbps. After looking at CPU usages, it is free more than 50%, I am not getting why low throughput in ipsec case. Below are my trial: 2nd, I tried to distribute multi-queue interrupt on mult-cpu but got same result. 3rd, I tried nic passthrough and enable RSS, I got good throughput and CPU usages. Please help me to understand how to increase vnet performance for VM. And also suggest me about ovirt setting. I have also seen some presentation in google around virtio-crypto but as I am using Guest and Host OS as centos 7.3, I can't use virtio-crypto device. Thanks, ~Rohit

The cache will not take immediately into effect. It is designed to save your cache disk and to load only repetitive data. Try to run your benchmark 20 times and you will notice slight improvement over reading the same object. Of course , you can use lvm cache in writethrough mode, but then it is recommended to use 2 cache disks (raid1 or lvm mirroring) .

vm unresponsive cpu soft lock on heavy operation
by Jayme 26 Jun '19

26 Jun '19

Basic setup notes: 3 node HCI running oVirt 4.3.3 using nodeNG for hosts. Storage is SSD backed with 10Gb network dedicated to gluster with jumbo frames enabled. The ovirt management network (which also acts as VM network) is 1Gb network Hosts are dell R720s w/ 256gb ram and E5-2690 procs I have a VM configured with 16Gb ram and 6 virtual CPUs. When this VM does a heavy operation (in this case it's dumping a large DB from a remote server) the load spikes quickly. When this happens the VM becomes unresponsive and in some cases I get cpu soft lock messages. I'm trying to determine where the bottleneck here is and how I can prevent the VM from becoming unresponsive when doing heavy tasks. Here is info from syslog showing the soft lockup: Jun 26 16:13:10 roble kernel: NMI watchdog: BUG: soft lockup - CPU#5 stuck for 23s!

VDI Brokering
by Ciro Iriarte 26 Jun '19

26 Jun '19

Hi!, What's the usual way to implement VDI with oVirt?, is it usuallly paired with a broker like UDS Enterprise / OpenUDS?, does it have anything embedded that can solve the VM assignment for a group of users?. Regards. CI.-

Graphics performance and Windows VM
by Ciro Iriarte 26 Jun '19

26 Jun '19

Hello!, I'm wondering what would be a good fit for decent graphics performance on Windows 10/2016/2019 + oVirt/KVM. Is there some kind of offloading with SPICE?, should I use RDP instead?, will vGPU backed by Nvidia cards help somehow?. The idea is to build a VDI environment for Windows VM, probably using OpenThinClient or a custom Linux image at the endpoint. The clients will use office suites, Java IDE, AutoCAD and Sketchup. Comments? Regards, -- CI.- --
