similar to: [PATCH][v6] PV extension of HVM(hybrid) support in Xen

Hi Keir The latest (hybrid) patchset again... 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"

Implement tsc adjust feature IA32_TSC_ADJUST MSR is maintained separately for each logical processor. A logical processor maintains and uses the IA32_TSC_ADJUST MSR as follows: 1). On RESET, the value of the IA32_TSC_ADJUST MSR is 0; 2). If an execution of WRMSR to the IA32_TIME_STAMP_COUNTER MSR adds (or subtracts) value X from the TSC, the logical processor also adds (or subtracts) value X

Call update_domain_wallclock_time on hvm_latch_shinfo_size even if the bitness of the guest has already been set, this fixes the problem with the wallclock not being set for PVHVM guests on resume from migration.

The initial values of the wallclock time in the shared info page are set for PVHVM guests when the hypercall page is initialized, since the hypercall page is not reinitialized on resume, the hypervisor wallclock time is not properly set on resume. Fix it by forcing an update of the wallclock values when the shared info page is mapped. Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>

The paravirtualized guests are offered wallclock time referenced to UTC only, while fully virtualized guests are given the option via the config file (localtime parameter) of starting with UTC time or local time. What would it take to optionally provide localtime to the paravirtualized guests as well? For a guest that launches assuming localtime as its time basis, then later deriving UTC from it

Hi, I find PV domin hung, When we take those steps 1, save PV domain 2, change system time of PV domain back 3, restore a PV domain or 1, migrate a PV domain from Machine A to Machine B 2, the system time of Machine B is slower than Machine A. the problem is wc_sec will be change when system-time chanaged in dom0 or restore in a

Changes from v2 to v3: - Use pfn_to_paddr() to get the address from frame number instead of doing shift directly. - Remove some unnecessary initialization code and add "static" to vmentry_fields and gpdptr_fields. - Enable the VMREAD/VMWRITE bitmap only if nested hvm is enabled. - Use clear_page() to set all 0 to the page instead of memset(). - Use domheap to allocate the

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 debug exception(#DB), overflow exception(#OF) and INT3(#BP),

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.

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

From: Yang Zhang <yang.z.zhang@Intel.com> The follwoing patches are adding the Posted Interrupt supporting to Xen: Posted Interrupt allows vAPIC interrupts to inject into guest directly without any vmexit. - When delivering a interrupt to guest, if target vcpu is running, update Posted-interrupt requests bitmap and send a notification event to the vcpu. Then the vcpu will handle this

This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP), INTn instruction emulation. Introduce new function vmx_inject_sw_exception() which deliver the software excetion, software interrupt and privileged software exception. Split hardware exception as a seperate function(old function vmx_inject_hw_exception()). Also Passed down intruction length

F.Y.I >>> "Tian, Kevin" <kevin.tian@intel.com> 08.11.27. 11:50 >>>Sorry for a typo. I did mean domU instead of dom0. :-) The point here is that time_resume will sync to new system time and wall clock at restore, and thus pv guest should be able to continue... Xen system time is not wallclock time which just counts up from power up. As Keir points out, only its

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
