similar to: [PATCH]: xl: fix broken cpupool-numa-split

Hi, although advertised via the usage output, xl cpupool-list -l just returns ERROR_NI, which does not show up on the console. Instead the output is empty, which is not exactly what --long hints to. To avoid confusion remove the line from the help output and just ignore the -l option properly until it gets finally implemented. Signed-off-by: Andre Przywara <andre.przywara@amd.com>

Since the key information can be fairly simply put on the command-line, there''s no need to require an actual config file. Also improve the help to cross-reference the xlcpupool.cfg manpage.

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

# xl cpupool-create ''name="pool2" sched="credit2"'' command line:2: config parsing error near `sched'': syntax error, unexpected IDENT, expecting NEWLINE or '';'' Failed to parse config file: Invalid argument *** glibc detected *** xl: free(): invalid pointer: 0x0000000001a79a10 *** Segmentation fault (core dumped) Looking at the code

Prevent xl from doing any operation if xend daemon is running. That prevents bugs that happened when xl and xend raced to close a domain. Changes since v1: * Add documentation to xl man page. * Permit the execution of commands that don''t modify anything. * Indent error message.

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 */

When using sedf scheduler in a cpupool the system might panic when setting sedf scheduling parameters for a domain.

Hi All it is possible to tune dom0/domU for better IO/network performance? Since I have changed to Cenots7 dom0, I have a really poor IO performance inside a PV VM. I have already done what is described on http://wiki.xenproject.org/wiki/Tuning_Xen_for_Performance It is better now but still significantly worse than with centos6 dom0 my settings: xen parameter: dom0_mem=1024M cpufreq=xen

Hi, while testing some APERF/MPERF semantics I discovered that this feature is enabled in Xen Dom0, but is not reliable. The Linux kernel''s scheduler uses this feature if it sees the CPUID bit, leading to costly RDMSR traps (a few 100,000s during a kernel compile) and bogus values due to VCPU migration during the measurement. The attached patch explicitly disables this CPU capability

HI, I am receiving the following error when I try to run blockcommit: ============================================================== root@farnsworth:/var/lib/libvirt/images# virsh blockcommit pg94-test vda --top /var/lib/libvirt/images/pg94-test.snap4 --active --pivot --verbose error: unsupported flags (0x4) in function qemuDomainBlockCommit

The current early-printk support for ARM is rather hard-coded, making it hard to add machines or tweak settings. This series slightly moves some code to gather UART settings in xen/arch/arm/Rules.mk instead of the actual .c files. Also it allows two different machines with different settings to share the same driver, which the last patch exploits to add support the Calxeda Midway hardware. This

Hi, currently we go through the emulator every time a HVM guest does an I/O port access (in/out). This is unnecessary most of the times, as both VMX and SVM provide all the necessary information already in the VMCS/VMCB. String instructions are not covered by this shortcut, but they are quite rare and we would need to access the guest memory anyway. This patch decodes the information from

Hi, we have some problems with acpidump running on Xen Dom0. On 64 bit Dom0 it will trigger the OOM killer, on 32 bit Dom0s it will cause a kernel crash. The hypervisor does not matter, I tried 4.1.3-rc2 as well as various unstable versions including 25467, also 32-bit versions of 4.1. The Dom0 kernels were always PVOPS versions, the problems starts with 3.2-rc1~194 and is still in 3.5.0-rc3.
