We migrated one over and one of the issues seems to be a severe degradation of video performance vis-a-vis the F20 host. The difference between rhel7 and f20 host is quite surprising. I get quite bad performance with f20 host as well (spice 0.12.4-3, qemu 2.0.0-5) Are your host configured with the same spice settings (in particular streaming-video and other compression settings) ? I have not specified any specific settings on the host for spice. If there are differences in the defaults then I could play around with that. Do you know what the differences might be? In particular on the F20 side I have: spice-server-0.12.5-2.fc20.x86_64 qemu-kvm-1.6.2-6.fc20.x86_64 And everything is peachy. On c7 host I have: spice-server-0.12.4-5.el7.x86_64 qemu-kvm-1.5.3-60.el7_0_0.2.x86_64 The setup is a C7 host, F20 guest and either C7 or F20 client, either local to the host or on the LAN. In this setup, the video plays fine for a few seconds, but eventually degrades to about 1fps with severe tearing of the video. Video does remain in sync with audio and there are no audio breakups. Any pointers on things to try? I have been investigating some video rendering issues with rhel7 guest on rhel7 host, seehttps://bugzilla.redhat.com/show_bug.cgi?id=1030024 However, even with the cogl fix and "PutImage BIG-REQUEST", the video regions seems to vary too much for the Spice video filter to perform well (using firefox/html5 video youtube). I believe it will need to be improved. I think these are both guest side fixes/changes, and my guest is F20, (actually the exact same VM as was running before on F20 host, but now on C7 host). So I think the cogl fix is not relevant (and I'm not permitted to see the PutImage BIG-REQUEST issue because it's a restricted bug). I have tried rebuilding the spice-server package from F20 and installing on C7 host, but it doesn't change anything. Which leaves me with qemu changes. Is there a "version" of the qxl hardware that's implemented in qemu that may be different? Your help would be most welcome to investigate and improve this further. I'll do my best :-) . Sometimes it's just a maze of twisty little passages, all alike... -- Thanks, David Mansfield Cobite, INC. ___ Spice-devel mailing list Spice-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/spice-devel

Maybe the reason is the difference of IO behavior, but I'm not sure. > > Are your host configured with the same spice settings (in particular > streaming-video and other compression settings) ? > > > The setup is a C7 host, F20 guest and either C7 or F20 client, either > > local to the host or on the LAN. > > > > In this setup, the video plays fine for a few seconds, but eventually > > degrades to about 1fps with severe tearing of the video.

[Spice-devel] video performance in rhel/centos 7 vs fedora 20
Hi All, We have been piloting deployments of VM using Fedora 20 host and guest and have been very happy with performance and stability in almost every respect, so a big thanks to all for this hard work. Things are looking great. Now we have been testing deployments of these same VMs (F20 guests) on rhel 7 (centos 7). We migrated one over and one of the issues seems to be a severe degradation of video performance vis-a-vis the F20 host.
