Hi all
I saw the SRIOV(82576 or 82599) NICs are fail to work with windows guest in Xen 4.4+qemu-xen-dir. After the windows 2k8 guest boot up, the NIC cannot get ip. And I only saw this issue with qemu-xen-dir. Qemu traditional is working well. Any one saw the same issue?
BTW: I try to bisect which qemu commit introduced the regression, but it seems the issue exists from the start of adding VT-d patch to upstream Qemu.
best regards
yang

My guest is, if it does not work with Xen 4.3 (with qemu-xen), then, it
never worked.
Would this be related to bug #22 (xl does not support specifying virtual
function for passthrough device) http://bugs.xenproject.org/xen/bug/22 ?
