I''m experiencing problem with win7 booting using QEMU vga. SDL boots really slow. VNC is boots faster but parts of the window is covered by black horizontal lines with no apparent screen refresh. IGD direct assignment boots fine. I''m using xm command so I''m not sure if this problem is xm specific. Using xl with the same guest config file does not seem to work. Is there a xl wiki page? I would like to give that a try. Allen _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I also see this issue with latest xen-unstable. Not only windows, but also the display of xwindows was broken. best regards yang> -----Original Message----- > From: xen-devel-bounces@lists.xensource.com > [mailto:xen-devel-bounces@lists.xensource.com] On Behalf Of Pasi K?rkk?inen > Sent: Saturday, November 06, 2010 7:09 PM > To: Kay, Allen M > Cc: xen-devel@lists.xensource.com; Ian Jackson; Stefano Stabellini > Subject: [Xen-devel] Re: qemu vga issue > > On Fri, Nov 05, 2010 at 04:51:51PM -0700, Kay, Allen M wrote: > > I''m experiencing problem with win7 booting using QEMU vga.

I don''t see this track_dirty_vram or anything out of ordinary in qemu logs. The problem occurred some time between cs# 22277 and cs# 22331. -----Original Message----- From: Stefano Stabellini [mailto:stefano.stabellini@eu.citrix.com] Sent: Tuesday, November 09, 2010 9:50 AM To: Kay, Allen M Cc: Pasi Kärkkäinen; xen-devel@lists.xensource.com; Stefano Stabellini; Ian Jackson Subject: RE: qemu vga issue On Sun, 7 Nov 2010, Kay, Allen M wrote:> I''m seeing this in xen-unstable tree. >Maybe vga dirty bit tracking is failing.
