Subject: Re: [BUG] win2008 guest cannot get ip through sriov
Date: Fri, 27 Oct 2017 07:27:41 +0000	[thread overview]
Message-ID: <B8376D2DEA074F45BA033984477C453E3B838AF3@shsmsx102.ccr.corp.intel.com> (raw)
In-Reply-To: <945CA011AD5F084CBEA3E851C0AB28894B8D1485@SHSMSX101.ccr.corp.intel.com>

This bug exist much long time, there are many discussion last year but not a solution then. I call out it now because there is a fix in qemu upstream:
commit a8036336609d2e184fc3543a4c439c0ba7d7f3a2
Author: Roger Pau Monne <roger.pau@citrix.com>
Date:   Thu Aug 24 16:07:03 2017 +0100

    xen/pt: allow QEMU to request MSI unmasking at bind time

The fix is not in qemu-xen tree yet, when will qemu-xen sync this fix? Is it possible to catch Xen 4.10's qemu-xen?

BTW, mail report bug is direct but not easy to track, I took much time to search this BUG report mail. @Lars, is there plan to introduce any bug system for Xen?


Thanks,
-Xudong
