Re: [ovirt-users] vdi over wan optimation

And by QoS, that likely means something you do outside of oVirt (Internet vs Intranet). Of course, applying QoS for "video" may make things horrible. Pumping large amounts of "live" important synchronized data costs a lot, it's the nature of the beast. Restrict it and you often end up with less than usable audio/video, especially if the data is unknown (e.g. a full remote desktop). Ideally, from a thin client perspective, the solution is to run as much of that as possible outside of the remote desktop. There's a reason why those very setup specific options exist out there for handling these types of VDI things (transparently). They are very restricted and of course have a slew of dependencies and usually a lot of cost. (and IMHO, often times go "belly up" within 5 years) I've seen some of these. Basically the thin client uses remote desktop, but when an embedded video happens, that is offloaded as a direct connection handled by the thin client (kind of like "casting" in today's world). I these VDI quests are Windows, RDP is likely going to do better than Spice, especially for remote audio and video. Doesn't mean it won't occupy all your bandwidth, just saying it performs better. With that said, remote desktop via other means, be that RDP, or NX, etc.. might be "better" than Spice. PSA: If these are Windows, be aware of Microsoft's VDI tax (the VDA). This is an arbitrary invented tax that Microsoft created strictly to get people to only user their hypervisor platform. It can cost a lot and it's required annually. In the past I used NX for my Linux "desktops". This worked well even over very low bandwidth connects, however, it assumed my business was not the source of network bottlenecks on the Internet. Just saying. Even so, things that did massive amount of work, be that large AV or IntelliJ (which does a gazillion window creates/destroys) were still some concern. We tweaked our IntelliJ profiles to help reduce the load there. Not a whole lot we could do with regards to audio/video but educate people. And no, I do not recommend 10 users playing PUBG via VDI. :-)
