Also, correct a copy&paste error in the documentation. Signed-off-by: Andrew Cooper <andrew.cooper3@citrix.com> --- This patch has been in the XenServer patch queue for a long time. It is more for debugging purposes than anything else, but is still proving to be valuable for tracking down bugs with HVM paging operations. diff -r 5af4f2ab06f3 -r e6ec5b2b717f

This patch initializes VMCB CR4 and shadow CR4 with 0 when VMCB is being constructed under nested paging mode. It complies with recent reset_to_realmode change in hvmloader.

There is a race condition between XEN_DOMCTL_SHADOW_OP_ENABLE_LOGDIRTY and HVMOP_track_dirty_vram hypercall. Although HVMOP_track_dirty_vram is called many times from qemu-dm which is connected via VNC, XEN_DOMCTL_SHADOW_OP_ENABLE_LOGDIRTY is called only once from a migration process (e.g. xc_save, libxl-save-helper). So the race seldom happens, but the following cases are possible.

And can we make p2m memory allocation from domain heap directly? -Xin _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi Everyone, I am running 3.2.1 on Centos 5.2 with HAP enabled, NUMA enabled, ACPI enabled and the dom0 allocated 512Mb. I have setup a single core 1Gb VM for performance testing under Windows 2008 Server. Most CPU results are within a few percent of theoretical max but Memory performance is about half what I expected. I get 3.22Gb/Sec Sandra 2009 Memory performance for a single Opteron 8350

Hi, (Assume VPID is available and enabled.) I''m trying to figure the TLB stuff with VPIDs. I understand from the poorly written chapter in the intel manual that if an HVM vcpu is running then only the TLBs tagged with the vcpu.VPID will be used. If xen or a PV guest is running, then VPID 0 TLBs are what will be used. Now I understand the hvm_asid_flush_vcpu upon new guest cr3, will

Dear R-help listers, I am now asking for helps on how to draw stacked ellipses to illustrate the shared and specific of multiple objects using R. My problem comes from my population genetics study. Now, I genotyped three species, and I get known about the amount of shared and specific haplotypes in each of the species and their combinations. I want to illustrate this result in three stack

This patch changes hap parameter from boolean to integer. So users can disable and enable hap using "hap=0" and "hap=1". It also prints out nested paging message under SVM.

Hi, V6: The only change from V5 is in patch #6: - changed comment to reflect autoxlate - removed a redundant ASSERT - reworked logic a bit so that get_page_from_gfn() is called with NULL for p2m type as before. arm has ASSERT wanting it to be NULL. Tim: patch 4 needs your approval. Daniel: patch 5 needs your approval. These patches implement PVH dom0. Patches 1 and 2

I''m new to Xen and I''ve never attended XenSummit but I did look at the Presentations & Videos and the Agenda from 2011 and I''m wondering if XenSummit 2012 be a good venue for learning more about designing, deploying, and managing Xen-based clouds? (The XenSummit 2012 agenda hasn''t been published yet.) Eric Pretorious Truckee, CA

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

Hi everybody, just to let you know that I uploaded the XenSummit schedule, see http://xen.org/files/XenSummit%20NA%202011%20Schedule.pdf More information on the summit is available at http://xen.org/community/xensummit.html - Todd Deshane will also upload the abstracts to this page next week and let you know.

I''m trying to get ceph working with decent performance (currently getting kb/second write performance!) and it seems that maybe the Debian wheezy kernel is just a bit too ancient. The 3.8 kernel from experimental works on bare metal, but when booting as dom0 under the xen hypervisor it crashes. I just figured out how to redirect xen output to my IPMI/BMC serial port and I see this:

I want to know any difference between writing, reading and shadow page table (for example performance).

I realized that I had failed to cover the hardware assisted paging case in my earlier p2m_ram_ro patches. This should fix it. Note that I say "should" - I don''t actually have an NPT or EPT capable box to test this patch on, so treat it with a modicum of caution. :) The patch also contains an update to the comment for the p2m_ram_ro type, so that it describes the current

Hi all! Did the nested xen stuff make it into the xen-unstable (4.1-rc1?) tree as suggested back in January by Tim Deegan?

Hi Ian/Stefano: I changed over to the PV clock for hybrid liked we talked at the hackathon. I still have the hang in update_wall_time() after dom0 switches to xen as clocksource. The source of hang seems to be in xen stime_local_stamp in cpu_time that suddenly jumps to a large 64bit value. I''ve been chasing to figure where that happens, and why for the hybrid and not PV. It appears the

This patch series includes a series of bugs related to p2m, ept, and PoD code which were found as part of our XenServer product testing. Each of these fixes actual bugs, and the 3.4-based version of the patch has been tested thoroughly. (There may be bugs in porting the patches, but most of them are simple enough as to make it unlikely.) Each patch is conceptually independent, so they can each
