Hi Gerd, Using qemu-upstream with pci-passthrough on xen-unstable previously worked fine. Since commit 0f7b2864d0d0c3ef2801f9214d8c510c80a220d1 (bisected) i see what i think are timing issues (video device is reporting buffer underruns).
Since that commit changes vnc code, i have disabled vnc (was default enabled, but i did not use it). Disabling vnc by using vnc=0 and nographic make thinks work like before. -- Sander
