SPICE fine tuning
Hi All,
Weve been playing with igel thin clients who were awesome at getting support for rhev 3.0 into the latest firmware. While almost everything works as expected there are issues in our set-up with video playback of any kind. We stumbled across this issue initially on youtube but hence have tested with any video of any format.
While using RHEV version 2.2 we did not have these issues. Is there any fine tuning we can do the spice or RHEV in general to help get this back to at least the performance we were experiencing with 2.2?
Thank you,
Marius

Hi Marius, great to see you here at the User Groups!
Can you please provide some details as to what exactly you are seeing, what the logs show, and how that differes from the same setup using 2.2?
Thanks,
Dan
I have found that YouTube performance is not as high in RHEV 3.0 as it was in RHEV 2.2. (I have only tried EL6 guests.)
Some issues in 3.0:
= The frame rates seem lower in 3.0.
= Making a video display full screen seems to make the client very slow to respond.
= When Firefox renders http://youtube.com, the background is sometimes corrupted.
EL6 desktops are performing considerably better after updating xorg-x11-drv-qxl from 0.0.14-10.el6 to 0.0.14-13.el6_2.
= Youtube video framerates seem to be improved.
= The responsiveness of full-screen youtube sessions is improved.
= I haven't yet seen corruption in the background of Firefox.
I'm also noticing some sluggishness with SPICE on the IGEL thin clients (IGEL rocks, btw...tried Dell/Wyse, and they wouldn't give me the time of day, but IGEL has everything working out of the box). The worst thing I'm seeing is that the mouse response is unbearably slow, but I'm also seeing some tearing and sync issues with full motion video/audio.
In some cases I'm able to move up to RHEL6, but I do have to keep RHEL5 around, and since RHEL5 and RHEL6 home directory profiles are incompatible, most folks use RHEL5.
Has anyone else found a way to overcome this behaviour?
