Fw: Re: [Xen-devel] Re: [PATCH] xen: mask XSAVE in cpuid since we don''t allow guests to use it
My major concern is DomU with disk=[''phy:/dev/sdb5,xvda,w''] NOT disk =[''tap:aio:/etc/xen/images/disk.img,xvda,w''] --- On Wed, 3/11/09, Boris Derzhavets <bderzhavets@yahoo.com> wrote: From: Boris Derzhavets <bderzhavets@yahoo.com> Subject: Re: [Xen-devel] Re: [PATCH] xen: mask XSAVE in cpuid since we don''t allow guests to use it To: "Jeremy Fitzhardinge" <jeremy@goop.org> Cc: "Xen-devel" <xen-devel@lists.xensource.com>, "Keir Fraser" <keir.fraser@eu.citrix.com> Date: Wednesday, March 11, 2009, 12:27 PM It''s not so important for me. The important thing is:- CentOS 5.2 PV DomU may be loaded only the very first time under Suse''s 2.6.27 xen-ified kernel & Xen Unstable ( the most recent). Attempt to shutdown and start it again gives VBD cannot be connected . Hotplug scripts not working. That''s a core issue, same behavior as under 2.6.29-rc7 (with XSAVE patch ). Kernel doesn''t seem to be a root cause. I believe Xen unstable is broken in some way.
