qemu in xen seems to be at version 0.10.2 qemu itself is now at version 1.01 What I''d like is a version of qemu in xen that has the Intel HDA audio driver that is available from version 0.14 onwards. This would allow HD audio under Windows 7 64bit which several people have been asking about because there are no 64bit sound drivers for the audio devices that qemu emulates. I tried backporting the Intel HDA audio but quickly realised that several of the interfaces have changed quite drastically. While I was able to fix some of them, there were more problems than first anticipated. Would it instead be easier to bring a newer version of qemu into xen? i.e. http://wiki.xen.org/xenwiki/QEMUUpstream In doing so, would this allow secondary pass through graphics for ATI as it is currently supported by the xen/qemu in the current xen 4.1.2 release? _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

Trad remains the default but we hope to switch in Xen 4.3. In the meantime if you run xen-unstable with the xl toolstack you can use device_model_version = "qemu-xen" in your configuration to select the upstream qemu.> In doing so, would this allow secondary pass through graphics for ATI > as it is currently supported by the xen/qemu in the current xen 4.1.2 > release?Currently upstream qemu is missing a couple of features, specifically save restore and pci passthrough. Patches for both have been posted to qemu-devel but they have not yet been applied. I think the lack of pci passthrough means no graphics passthrough. Ian.
