Both for both sets of tests. XenServer, as of 6.5, contains both a debug and non-debug hypervisor, built from identical source. In trunk, the debug hypervisor is used by default. Tests such as performance tests explicitly switch to the non-debug hypervisor as part of their setup. ~Andrew ___ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

Hi all, in preparation for the release we need to update some wiki pages, as well as in-tree docs First of all, any new features for which any of you have written new wiki pages should be marked with [[Category:Xen 4.5]]. Either do this, or reply with URLs to pages and I will do so Otherwise, I created boilerplate pages for various pages and tracked the status on http://wiki.xenproject.org/wiki/Category:Xen_4.5 @Russell: you may want to update the XM to XL pages or create a new one and add your video == The following pages need to be reviewed and updated == * {{NotDone}} [[Linux PVH]]: ** Add PVH Dom0 information ** Review/correct the '''Things that are broken''' section ** Review/correct the '''Items that have not been tested extensively or at all''' * {{NotDone}} [[Xen ARM with Virtualization Extensions]] ** supported platforms need to be updated and ** all platforms that are supported in 4.5 tagged appropriately with [[Category:Xen 4.5]] == Lars will fix == * {{NotDone}} [[Xen Project 4.5 Acknowledgements]] ** Lars will do this. * {{NotDone}} [[Xen Project 4.5 Feature List]] ** Lars will copy from the blog announcement when ready (Sarah is currently making some final changes) == For Konrad and others == * {{NotDone}} [[Xen Project Release Features]] - main 4.5 features need to be added. Please reply to the thread and I will add that page. ** The key changes normally are changes to scalability/memory/etc. limits - maybe Jan(x86) and Ian(ARM) can look let me know of changes ** Also new platforms, changes to experimental features, etc. ** Probably the new scheduler should be added - is there a wiki page? ** Any other major new features that are worth highlighting? I can go through the press release and the release note * {{NotDone}} [[Xen Project 4.5 Release Notes]] - needs to be created ** http://wiki.xenproject.org/wiki/Xen_Project_4.4_Release_Notes were pretty lightweight ** I think we should keep it that way. We should probably mainly focus on known issues @Konrad: what's your view? == Missing pages == * {{NotDone}} [[Xen Project 4.5 Man Pages]] ** need to clone [[Xen Project 4.4 Man Pages]] and point to the correct branch when the 4.5 branch has been created ** if there are new documented features in in-tree docs then add them ** if there are irrelevant features such as XM, remove links to docs (probably the docs should be removed from the git tree also) Cheers Lars On 16 Dec 2014, at 16:13, konrad.w...@oracle.com wrote: Xen 4.5-rc4 was out on Monday (Dec 15th).

Thank you for doing this testing! * Fail to reliably boot on IBM Flex x222 blades, apparent regression from 4.4 I have declared this a latent BIOS bug, and not a regression from 4.4. Across regular reboots, the exact positions of the ACPI tables, and the e820 layout is unstable. The first consistent difference between 4.4 and 4.5 is that 4.4 reports 1 MBR signature while 4.5 reports 0. This is because the int $0x13, ah=2 call is returning differently. I can get the call to return differently (and correctly for 4.5) by simply making the boot trampoline larger (with my debugging routines but not being called). This sounds very familiar, but I can't place where I saw mention of a similar issue. * VM fail to resume on upgrade from Xen 4.5 This is the issue I am currently looking into. Currently, all the upgrade from older XenServer tests are failing due to VMs crashing on resume. I have not yet identified whether this is a XenServer issue or Ugh. I have got to the bottom of this, and it it turns out to be a legacy - migration v2 conversion bug which only surfaced now because Xen-4.5 is more strict than Xen-4.4. HVM_PARAM_PAE_ENABLED is sent out-of-band in legacy, but passed to xc_domain_restore(), which does a set_param(), unconnected with any contents of the stream. Migration v2 saves and restores it properly, but the legacy - v2 conversion neglected to combine the out-of-band information. No VMs blew up because all versions of Xen at that point were not correctly auditing updates to cr4 against the domain cpuid policy. Xen-4.5 now does, causing #GP faults on cr4 writes for guests which had PAE enabled before migrate. I shall be fixing this in the migration v2 series, and also looking for any other obvious out-of-band information which needs injecting into a converted stream. With this fixed(^W hacked around for now), I have identified and solved all discrepancies XenServer testing has noticed between Xen-4.4 and Xen-4.5 so far. There will be another full nightly test happening tonight (based on c/s 7e88c23 libxl: Tell qemu to use raw format when using a tapdisk), and some stress and scale tests if time allows. ~Andrew ___ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

I was under the impression you had some patches which would solve a majority of the issues? And after the discussion with Ian Jackson the way to exec was solved? And for the other - the SELinux context and how to figure this out - I thought (I will have to double-check it tomorrow) that I mentioned it might make sense to talk to the SELinux maintainers to see if they have any recommendation?

This is the last RC and then we have the General Release on Jan 7th! Details for the test-day are at http://wiki.xen.org/wiki/Xen_4.5_RC4_test_instructions In terms of bugs, we have: From the XenServer testing. Thank you for doing this testing! * Fail to reliably boot on IBM Flex x222 blades, apparent regression from 4.4 I have declared this a latent BIOS bug, and not a regression from 4.4. Across regular reboots, the exact positions of the ACPI tables, and the e820 layout is unstable. The first consistent difference between 4.4 and 4.5 is that 4.4 reports 1 MBR signature while 4.5 reports 0. This is because the int $0x13, ah=2 call is returning differently. I can get the call to return differently (and correctly for 4.5) by simply making the boot trampoline larger (with my debugging routines but not being called). This sounds very familiar, but I can't place where I saw mention of a similar issue. * VM fail to resume on upgrade from Xen 4.5 This is the issue I am currently looking into. Currently, all the upgrade from older XenServer tests are failing due to VMs crashing on resume. I have not yet identified whether this is a XenServer issue or Ugh. a Xen issue. Lifecycle operations on 4.5 itself are all fine including both suspend/resume and migrate. ~Andrew ___ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
