Might be. Packaging has been done by Ubuntu. Packages uploaded to Repos I just installed *.deb packages been already patched and compiled , but can get source before patching as well. I''ve zipped hvmloader installed via system setup of xen tools, e.g. after patching Boris --- On Tue, 7/19/11, Stefano Stabellini <stefano.stabellini@eu.citrix.com> wrote: From: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Subject: [Xen-devel] Re: Problem with Xen 4.1 on Ubuntu 11.10 ( Oneiric Ocelot) (HVM DomUs crash) To: "Stefano Stabellini" <Stefano.Stabellini@eu.citrix.com> Cc: "Boris Derzhavets" <bderzhavets@yahoo.com>, "xen-devel@lists.xensource.com" <xen-devel@lists.xensource.com>, "Keir Fraser" <keir@xen.org>, "Konrad Rzeszutek Wilk" <konrad.wilk@oracle.com> Date: Tuesday, July 19, 2011, 2:01 PM On Tue, 19 Jul 2011, Stefano Stabellini wrote:> On Tue, 19 Jul 2011, Boris Derzhavets wrote: > > Alpha 2 already has Xen 4.1 packaged and ready for testing. > > It appears to be known bug that HVM DomUs crash at Xen 4.1 Dom0 with different "pvops'''' > > kernels ( in particular 3.0.0-5-generic Ubuntu) , but not only on Ubuntu . > > Here is report for Fedora 15 : > > > > http://www.gossamer-threads.com/lists/xen/users/213049?nohighlight=1#213049 > > > > Ubuntu developers are pretty sure that Xen Host will be built with no problems. > > Would it be possible to issue a patch for Xen 4.1 to fix the problem ? > > Actually two distros are affected Fedora 16 and Ubuntu 11.10 ( maybe Debian - here > > i am not sure ) > > First we need to understand what the problem is.

These are the error logs that I get on the xen serial when starting an HVM guest: (XEN) HVM1: HVM Loader (XEN) io.c:194:d1 MMIO emulation failed @ 0018:9ffff: 00 e0 de be 00 83 (XEN) hvm.c:1099:d1 Triple fault on VCPU0 - invoking HVM system reset. The problem appears to be hvmloader, in fact I replaced the hvmloader that comes with ubuntu alpha 2 with the one I compiled myself out of xen 4.1.1 and everything worked as expected. Do you have any patches to xen that might have broken hvmloader? -----Inline Attachment Follows----- _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
