Desktop Environment/GUI Cannot Start After I Have Installed Xen 4.1.3-rc1-pre and Linux Kernel 3.3.0-rc7
Dear All, I have just compiled and installed Xen 4.1.3-rc1-pre and the latest Linux kernel 3.3.0-rc7 in Ubuntu 11.10 Final Release. I am able to login to my Desktop Environment/GUI when Linux 3.3.0-rc7 is *enabled* and Xen 4.1.3-rc1-pre is *disabled*. However, when Linux 3.3.0-rc7 and Xen 4.1.3-rc1-pre are both enabled, I am unable to start the default desktop environment/GUI. The menu bar and status bar in Unity won''t show up. Although I cannot login via the GUI, I can still login through the text console/terminal. I am able to see that Xen is running properly by executing the command "sudo xm list". "xm list" shows that Domain 0 is running properly. It''s just that the Desktop/GUI won''t start up. The errors which I think are the most important are reproduced below: [ 15.837793] [drm] Initialized drm 1.1.0 20060810 [ 16.494498] [drm] MTRR allocation failed. Graphics performance may suffer.

Re: Desktop Environment/GUI Cannot Start After I Have Installed Xen 4.1.3-rc1-pre and Linux Kernel 3.3.0-rc7
Hi, I have solved the problem. Xen 4.1.x is incompatible with the onboard graphics of Intel DQ45CB motherboard. I have switched the graphics adapter to NVIDIA 8400 GS PCI Express x16 and the combination of Xen 4.1.3-rc1-pre, kernel 3.3.0-rc7, and NVIDIA 8400 GS works well (Xen 4.1.x is compatible with NVIDIA 8400 GS graphics). I have also compiled the *latest* linux kernels 3.x.x for Ubuntu 11.10 Final Release for you to use. You may download the *latest* linux kernels from the following links: (1) linux-image-3.3.0-rc7-xen-teo.en.ming-sgp_14.mar.2012_amd64.deb Download Link: http://www.mediafire.com/?kn505tufic974zj (2) linux-headers-3.3.0-rc7-xen-teo.en.ming-sgp_14.mar.2012_amd64.deb Download Link: http://www.mediafire.com/?cj1a1k82v516jp0 (3) linux-image-3.2.11-xen-teo.en.ming-sgp_15.mar.2012_amd64.deb Download Link: http://www.mediafire.com/?mkh4rd6tobit35b (4) linux-headers-3.2.11-xen-teo.en.ming-sgp_15.mar.2012_amd64.deb Download link: http://www.mediafire.com/?xzxk5sbaujbnkkg Yours sincerely, Teo En Ming (Zhang Enming) On 14/03/2012 23:39, Teo En Ming (Zhang Enming) wrote:> Dear All, > > I have just compiled and installed Xen 4.1.3-rc1-pre and the latest > Linux kernel 3.3.0-rc7 in Ubuntu 11.10 Final Release.

Stefan, can this option be set in the Ubuntu kernels?

Re: Desktop Environment/GUI Cannot Start After I Have Installed Xen 4.1.3-rc1-pre and Linux Kernel 3.3.0-rc7
Stefan, We are developing a pvops kernel based off of the Ubuntu 12.04 3.2.x kernel, with some merges from Konrad''s development trees, along with some other patches. My full config is attached. We are running on a wide variety of hardware - both nVidia (as long as you use nouveau) - and Intel. We have CONFIG_INTEL_IOMMU set to "y" (this used to be DMAR) The guys at Intel recommended this be turned on, when we were seeing very similar crashes. Without rehashing our entire email train - the executive summary is: <snip> The major problem is related to CONFIG_DMAR_TABLE, which if not set i915 driver uses virt_to_phys for address translation which is not Xen aware. You can have a check whether it’s the same case in your environment: CONFIG_DMAR_TABLE=y CONFIG_INTEL_IOMMU=y # CONFIG_INTEL_IOMMU_DEFAULT_ON is not set there’s some renaming happened recently from CONFIG_DMAR to CONFIG_INTEL_IOMMU, which you can also check with your earlier .config. </snip> Hope this is helpful Ben Guthro Virtual Computer, Inc.
