similar to: [HYBRID] : mapping IO mems in the EPT

The issue at hand is that any prolonged usage of radeon or nouveau driver ends up corrupting the file system or we end up with mysterious crashes of applications. There are three ways of fixing it: a). A proper fix: https://lkml.org/lkml/2012/2/10/228 . I posted the same fix for 3.2 way back in December but it got nowhere. The recent posting has also been meet with silence. Not being happy

Hi, On paravirt x86 (both 32- and 64-bit), since cset 13998: http://xenbits.xensource.com/xen-unstable.hg?rev/13998 we translate all ptes from being mfn-based to pfn-based when the hardware _PAGE_PRESENT bit is cleared. We do this for PROT_NONE pages, which appear to the HV to be non-present, but which are special-cased in the kernel to appear present (a different bit in the

It was decided during xen patch review that xen map the iomem transparently, so remove xen_set_clr_mmio_pvh_pte() and the sub hypercall PHYSDEVOP_map_iomem. --- arch/x86/xen/mmu.c | 14 -------------- arch/x86/xen/setup.c | 16 ++++------------ include/xen/interface/physdev.h | 10 ---------- 3 files changed, 4 insertions(+), 36 deletions(-) diff --git

Hello I''am using xen 4.1.1. I''ve created 4 domU successfully, but EPT Table is not enable, and I can''t enable it. I''ve try different option in grub (iommu=eptable, ....). According to "xm dmesg", my PC is compatible with EPT (XEN) VMX: Supported advanced features: (XEN) - APIC MMIO access virtualisation (XEN) - APIC TPR shadow

From: Mircea C?rjaliu <mcirjaliu at bitdefender.com> This change is needed because the introspection tool can write-protect guest page tables, exec-protect heap/stack pages and let KVM emulate the instruction that caused these violations.

I am using libvirt 1.2.20. I noticed that when running some VMs (CentOS ) with 2G ram, 2CPUs each for some reason they go from 'state=running' to 'state=paused'; and they can't be restarted. They are un-usable. When this happens I get the following in dmesg output: [ 46.595265] EPT: Misconfiguration. [ 46.595271] EPT: GPA: 0xfee000b0 [ 46.595275]

From: ?tefan ?icleru <ssicleru at bitdefender.com> Add a view mask for kvm_mmu_zap_all() in order to allow zapping shadow pages for specific EPT views. This is required when an introspected VM is unhooked. In that case, shadow pages that belong to non-default views will be zapped.

This fixes a bug in changeset 22526:7a5ee3800417, where the wrong value is read when deciding whether to flush the VTd tables. The effect is minor: in situations where the p2m entry is changed but the mfn is the same, the VTd tables will be unnecessarily flushed. old_entry is left untouched in the second case, since having a present old_entry will cause the an unnecessary check to be taken at

Hi Xen developers and enthousiasts, Recently I have been having a lot of problems with HVM hosts on a dual Xeon E5606 box. Problem is that HVM hosts don''t work on it at all and crash the server. Today I got the logging to work over an IPMI console so then I compiled a fresh xen-unstable. Apart from the message I posted in the subject the call trace reads as follows: (XEN) Xen call

Hi, I am really confused about NPT walks for guest page table , and eager to know the details about it. It is treated as data writes even if the access itself is a code read in AMD NPT.I just want to know : is it the same in EPT? Could anyone help me? I would like to know that very much Thank you in advance Bo Ma _______________________________________________ Xen-devel mailing list

I'm trying to get HOBOware Pro (http://www.onsetcomp.com/products/software/), a tool that interfaces with a USB based datalogger, to work under Wine. I have installed it, and it fails with the message: Code: Error occurred during initialization of VM Could not reserve enough space for object heap This seems to be fairly common among Java apps, and the solution appears to be setting -Xms

Hello, With many intel chips now supporting Vt-d, and many laptops sporting hybrid graphics (integrated + discrete), I would expect there is some combination that would allow this type of setup. Pass the discrete graphics card through to a guest os, while the integrated graphics are used by Dom0. Any suggestions? Thanks, Josef Wells _______________________________________________ Xen-users

Hi, I would like to ask if there are any known issues with booting an ISOLINUX hybrid iso image from a USB Flash Drive on older Dell PC's (i.e. P4 2.2GHz). I've tried several that one should just be able to write to UFD and boot, but they all fail on my hardware. I get "isolinux.bin missing or corrupt" message on screen. This function would be very convenient for me, so

I should probably have pointed out in the previous note that CD-ROM/HDD hybrid mode is obviously rather experiemental at this point. I would love to get some feedback on it, though. -hpa

Hi all, Does anyone know if there's R code available for doing Hybrid Multidimensional Scaling (or Semi-Strong HMDS, e.g. Belbin 1991 J. Veg. Sci. 2:491-)? I've found only commercial software that does it. Thanks, Anni

Hi. I have built a levelplot with 3 variables, X, Y, and Z where X and Y are the two axes and Z represents the intensity (i.e. Z~X*Y). Now I want to adjust the size of the grid (like a mosaic plot) where the size of each grid is weighted by a variable, W. Just wonder how can I do that with levelplot? I tried exploring mosaic plot. How can I manipulate the "col" option to make it

anybody use them on Gluster? They seem to be almost the same cost as spinning metal these days. In fact I was trying to get some 2.5 inch 2TB drives on a vendor and all they had was the firecuda SSHDs or the really expensive "Enterprise" variety. Our use case would be for VM hosting (Rep2 + Arb). I'm not sure how the SSD cache would pan out with the shards. I've googled
