Hello, We want to use Xen with spice and we are testing to make sure we can get reasonable video performance from it, but our tests are so far not encouraging. GUI is slow, the mouse pointer doesn''t move smoothly and Youtube videos go step by step (we had the worst performance with cirrus video, followed by qxl, followed by stdvga). A comparative test on qemu-kvm with qxl and spice showed none of these problems (same hardware, same guest system (Debian wheezy), qxl driver and spice-vdagent installed). Can someone help us understand what is currently the bottleneck of video performance in Xen + spice, and how far we are from a solution? What can we do to narrow down the problem? What needs to be done to have a working qxl in Xen? Thanks, LG -- View this message in context: http://xen.1045712.n5.nabble.com/Xen-spice-video-performance-tp5702637.html Sent from the Xen - User mailing list archive at Nabble.com.
