similar to: [PATCH 0 of 3] xen: sched_credit: fix tickling and add some tracing

Address some credit2 issues. This patch series, along with the recent changes to the cpupools interface, should address some of the strange credit2 instability. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

in _csched_cpu_pick(), as not doing so may result in the domain''s node-affinity mask (as retrieved by csched_balance_cpumask() ) and online mask (as retrieved by cpupool_scheduler_cpumask() ) having an empty intersection. Therefore, when attempting a node-affinity load balancing step and running this: ... /* Pick an online CPU from the proper affinity mask */

Add a xen command-line parameter, sched_credit_tslice_ms, to set the timeslice of the credit1 scheduler.

From: Nate Studer <nate.studer@dornerworks.com> Add a utility function to update the rest of the timeslice accounting fields when updating the timeslice of the credit scheduler, so that capped CPUs behave correctly. Before this patch changing the timeslice to a value higher than the default would result in a domain not utilizing its full capacity and changing the timeslice to a value lower

Aiming at a release later in October (before Xen Summit I would hope), I''d like to cut RC1 next week. Please indicate any bug fixes that so far may have been missed in the backports already done. Jan

Hello everyone, Reposting with after having applied the (minor) fixes suggested by Wei and Jan. Allen, if you can tell us what you think about this, or suggest someone else to ask some feedback to, if you''re no longer involved with VT-d, that would be great! :-) -- As already discussed here [1], dealing with IOMMU faults in interrupt context may cause nasty things to happen, up to

Hi all, This is the second take of a patch that I submitted some time ago for allowing specifying vcpu pinning taking NUMA nodes into account. IOW, something like this: * "nodes:0-3": all pCPUs of nodes 0,1,2,3;  * "nodes:0-3,^node:2": all pCPUS of nodes 0,1,3;  * "1,nodes:1-2,^6": pCPU 1 plus all pCPUs of nodes 1,2    but not pCPU 6; v1 was a single patch, this is

Hi all, These days I installed xen 4.3 unstable from source and recompiled qemu upstream with spice support. After xl create , the windows domU started successfully and spice client can visit the VDI. However, it display blue screen before entering the windows welcome screen. Is it a bug in current upstream qemu support? My domU configuration file is: builder =

Hi Ian-s, Two small patches for OSSTest. The first one turns on compiling the Linux modules for MegaRAID SAS, needed for the ultralisk machine in the Cambridge lab. The second adds an entry in the README file about the RebootTimeExtra host property, which I also needed to use for ulttralisk, as scrubbing 368GB of RAM really takes a lot! git://xenbits.xen.org/people/dariof/osstest.git misc Let

Hello, I have asked this question in Xen-users mailing list too. But since it involves compiling from source, I realised asking this here makes more sense. Please forgive me for the spam. I am relatively new to Xen and need help compiling and installing Xen from source. Using some tutorials online, I have got Xen working with the ''yum install xen'' method. I used virt-manager

Hello, Third version of the NUMA placement series Xen 4.2. All the comments received during v2''s review have been addressed (more details in single changelogs). The most notable changes are the following: - the libxl_cpumap --> libxl_bitmap renaming has been rebased on top of the recent patches that allows us to allocate bitmaps of different sizes; - the heuristics for deciding

i installed both xen-4.2.1 and libvirt-1.2.0 from the source only. i moved with the latest version of libvrirt. i did the gdb in libvirt-1.2.0 and i raised the bug.
