Looking at the hook you posted earlier: https://github.com/oVirt/vdsm/blob/master/vdsm_hooks/spiceoptions/before_... It needs user to provide the options and for this feature to work streaming=filter or streaming=all must be giving to spice server to enable streaming. > do i need to change something on host or engine I need to > solve youtube or other video problems For mjpeg encoding, you don't need to change anything. For x264/vp8 with GStreamer, spice must be built with GStreamer option enabled. You can check if that's the case for your spice server library by running ldd in the .so file, e.g: spice (master 717ed19a) $ ldd ~/dev/lib64/libspice-server.so | grep -i gst libgstreamer-1.0.so.0 => /lib64/libgstreamer-1.0.so.0 (0x00007f393b57d000) libgstapp-1.0.so.0 => /lib64/libgstapp-1.0.so.0 (0x00007f393b568000) libgstbase-1.0.so.0 => /lib64/libgstbase-1.0.so.0 (0x00007f393b0df000) Plus, you need the plugins for encoding in your host. > Additionally, steraming needs to hardware accelerator, all > streaming apps or offers hardware acceletor for best performace As mentioned earlier, the encoding parameters are hardcoded [0] so, even if you argue that gpu is preferred, that's not currently supported but patches are welcome!

Spice streaming in the host supports two encoders: a mjepg implementation in spice and a gstreamer one with support to mjpeg, h264 and vp8. The encoding parameters are hardcoded but I've tested them all in the past and worked well for youtube-like scenarios... but feel free to open bugs upstream if not [0] [0] https://gitlab.freedesktop.org/spice/spice Good luck with the hook.

You say youtube videos in bottom of the email. Is it flash or html5? Are standard and cinema-mode-sizes working OK, or all sizes are affected? Bear in mind that video is in general most cpu-heavy use case for spice because lots of work needs to be done on guest vCPU (decode, upscale to fullscreen) and host CPU (mjpeg-encode the actual video size: fullhd for any video played in full screen on full hd monitor). > Qxl drivers are installed and spice-vdagent works > >> as expected on the guest side. > > What hosts and clients do you use, what is your network environment? > ubuntu spice-client-gtk (0.22) for the client side, That's pretty old, could you update to distro with at least spice-gtk 0.26 (which itself is ~1 year old, 0.30 was released recently)? > and my hosts (latest > intel CPU and 128 GB of RAM) are centos 7.1 one connected to a FC > storage domain.

The problem aren't mainly effect but it's the compositing which changes screen updates from lot of operations on limited area of screen to updates of whole screen, making lots of spice optimization pointless. Some time ago (~2 years), gnome-shell rendering was improved so that stream didn't update whole display but just the video stream area which can be detected as a stream and transferred in an optimized way. I'd bet that your issue is one of those two described above (CPU overloading or streaming detection error) but further testing is needed to find what it really is. > > > > David > > > >> However, it is amazing to see that glxgears benchmarks are good... > >> I wonder how it is possible to adopt such a vdi solution when the user > >> experience is so bad. > >> I may miss something and may need recommandations of experimented vdi > >> users :) > >> Thank you for your help. > >> > > > Ovirt is an awesome product, and I've been used to be pleased with its > great integrated quality tools, that's why I'm supposed to mistake in my > configuration. > I don't know the vdi part, but problematic is not the same compared to > the server virtualization.

[ovirt-users] Re: VDI

by Leo David

Thank you very much for the informations. I'm am sorry for my lack of knowledge, but the vGPU / vm graphical performance part is a bit confusing for me at the moment. As far as i've understood, if some real decent graphical performance is needed for the vms, the only proper way is to install a grid supported gpu card on the hypervisor, and have the "slices" assigned to the vms. A rough look show that this will add at least 4k - 5k dollars per node... Just as a reference, its only about "office type" vdi's that only do web browsing and sometimes youtube videos / skype calls. Any thoughts for a more less expensive way to achieve this ? Again, thank you very much !

by Leo David

Thank you for sharing the informations Alex, they are very helpfull. I am now able to get sound from the vms, although performance is pretty poor even with "adjust for performance" setting in Win10. Cannot even talk about youtube video playing - freezing and crackling. Could you please be so kind to share the following infos: 1. Have you upgraded the "spice-server" installed on the hosts with a newer version than 1.4.0 ? If so, could you provide me how could I get these packages ? 2. What graphic card have you used for getting better graphic performance with the vms ? Im trying to understand what "accepted" card could I use with my 1U chassis servers... 3. Is it only needed to install the card and the platform will alocate physical video memory to "desktop" vms ? ( Will the card RAM be automatically shared across the desktop tyoe vms running on top of the host ? ) 4. Is it necesarilly to activate sr-iov in the hosts bios or any other platform configurations ? I am really sorry for asking too many things, but im just trying to get these vdi vms working at least decent... Thank you so much !

I am the middle of vdi implementation as well, and i'm having issues with the spice console since 4.2, and it seems that latest 4.3 is still having the problem. What am i confrunting is: - spice console is very slaggy and slow for Win10 vms ( not even talking about running videos..) - i can't find a way to get audio from the vm At the moment i am running 4.3, latest virt-viewer installed on the client, and latest qxl-dod driver installed on the vm. Any thoughts on solving video performance and audio redirection ? Thank you again, Leo On Mon, Sep 23, 2019, 22:53 Alex McWhirter <Alex(a)triadic.us> wrote: To achieve that all you need to do is create a template of the desktop base vm, make sure the vm type is set to desktop. Afterwards just create new vms from that template. As long as the VM type is set to desktop each new VM will use a qcow overlay on top of the base image. Taking this a step further you can then create VM pools from said template, allowing users to dynamically be assigned a new VM on login. Granted pools are usually stateless, so you need to have network file storage. We use pools for windows 10 VDI instances, where we use sysprep to autojoin the new pool vm to the domain where redirected folders are already setup. For VDI only use spice protocol. By default we found spice to be semi lackluster, so we do apply custom settings and we have recompiled spice on both servers and clients with h264 support. This is not 100% necessary, but makes things like youtube much more usable. We have also backported some audio patches to KVM. CentOS 8 should resolve a lot of these customizations that we've had to do. As far as updating, pretty much. We create a VM from the template, update it, then push it back as a new version of the template. The pools are set to always use the latest template version. Users have to log out, then back in to the VDI system in order to get the new image as logging out will destroy the users current instance and create a new one on log in.

I am approaching and studying oVirt in order to propose the solution to a customer as a replacement for a commercial solution they have now. They only need Desktop virtualization. Sorry for the silly question, but I can't find a way to deploy a VM (template) to users as a "linked-clone", meaning that the users' image still refers to the original image but modification are written (and afterwards read) from a new location. This technique is called Copy-on-write. Can this be achieved with oVirt? Then, what is the Best Practice to update WIndows OS for the all the users? Currently they simply "check-out" the Gold Image, update it and check-in, while all users are running... Fabio On Mon, Sep 23, 2019 at 8:04 PM Alex McWhirter <Alex(a)triadic.us> wrote: yes, we do.

Re: [ovirt-users] engine upgrade 4.0 => 4.1, no more engine console available

by Martin Sivak

Hi Nelson, sorry to not tell you sooner, but we are already busy looking into it. Opening a bug would be a good move as would be attaching the hosted engine agent logs (/var/log/ovirt-hosted-engine-ha/agent.log iirc) from before and after the upgrade.
