Hello, I saw some patches about PCI-passthrough for HVM(non-IOMMU) and I am interested in it. I want to assign my graphics card(nVidia GeForce 7900GS) to an HVM domain (Vista) in order to run 3D-intensive work(for example, 3D-games). What I want to ask is that is it really possible to pass the graphics card to HVM domain running Vista now? Tha...

We have tested the latest xen on VT platform with Intel 965/5000P chipset. Here is the test summary: Issues: ========================= 1). VBD could not work well Partial support is added in c/s 13198, but the loader still complains that symbol "irq_to_evtchn_port" is missing. 2). IA32E: IA32E vista can''t boot up normally, it gives a blue screen. Then the qemu window

Hi, I am trying to setup Xen to use "PV on HVM". For this, I did the following. (1) I followed the tutorial at http://wiki.xensource.com/xenwiki/Fedora13Xen4Tutorial to setup Xen4.0.1 on Fedora13. I am able to run virt-manager and create a Fedora 13 guest. (2) I followed the tutorial at http://bderzhavets.wordpress.com/2010/05/27/pv-on-hv...

Changes from v1: - Define new struct hvm_trap to represent information of trap, include instruction length. - Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of wrappers around that function for existing callers, so that their parameter lists actually *shrink*. This series of patches fix the mistake for debu...

Hi Keir The latest (hybrid) patchset again... Change from v5: Address the comments from Tim. Change from v4: 1. Add support for PV clocksource on HVM. (Replace evtchn enabling with pv clock enabling). 2. Update the patch following Tim''s comments. Change from v3: 1. Minor polish the patchset. Replace several specific is_hvm_pv_evtchn_domain() judgement. 2. Name changed... Change from v2: 1. Change the name "hybrid" to...

Hi all, I find that SPEC cpu2k benchmark will always fail (9 of 10 times) for ia32 smp hvm guest with 4 vcpus. I used 4 users parameter to run cpu2k and assign 1G memory for the guest, but it will always fail when running 164.zip case and report warnings as the attachments. However, cpu2k could be run successfully in native linux and xenU guest with the same configuration. Anyone has ide...

Hi I need to use hypercalls from HVM domain (e.g. HYPERVISOR_add_to_physmap). However, it does not work when I am trying to invoke it from HVM Linux guest. Basically, I don''t see that anything happens on hypervisor''s side. I also grep''ed the guest code for ''vmmcall''/''vmcall'...

The aim of this patch is to define a stable way in which PVH is going to do AP bringup. Since we are running inside of a HVM container, PVH should only need to set flags, cr3 and user_regs in order to bring up a vCPU, the rest can be set once the vCPU is started using the bare metal methods. Additionally, the guest can also set cr0 and cr4, and those values will be appended to the default values set by Xen. Signed-off-b...

Hi list, I''ve read about recent efforts to push pv-on-hvm drivers to Linux mainline and I''m curious to know the cause for this. What''s the advantage over using pv_ops directly and booting the kernel paravirtualized? Are there plans to move Linux domUs closer to the KVM way (from an architectural point of view)? Hope you can help. R...
