Hallo,
as I want to switch from XEN to KVM I've made some performance tests
to see if KVM is as peformant as XEN. But tests with a VMU that receives
a streamed video, adds a small logo to the video and streams it to a
client
have shown that XEN performs much betten than KVM.
In XEN the vlc

Hello,
now I was able to start the guest vmu with disk virtio, and some of the
tests with disk involvement even improved a bit.
But the test in which a logo is added to the video stream does not

Does there exist a similar AMD parameter?
