similar to: Xend highly uses CPU with multiprocessor setup

Package: xen-utils-4.0 Version: 4.0.1-5.2 After clean upgrade from Lenny I got xend highly use CPU resources causing domU don't being created - due to timeouts for vifs and vbds (mostly CPU Steal Time was increasing - no iowaits). Tried Xen boot options acpi=noirq|ht without success. Option acpi=off solved that issue, but performance of the server was horrible. The final workaround was to

I was wondering if anybody else had seen the following: I have a multiprocessor system (Intel P4). I use Wine to run the Tasking 56300 DSP compiler (Tasking, brilliant folks they are, *had* a Linux version, that they DROPPED support for!). Doing a build of a fairly large project (over a hundred files), with nothing much else going on, the compiles run very slowly, the system is at less than

Package: xen-utils-common Version: 4.0.0-1 Consider removal of xenstored tdb file (located at /var/lib/xenstored/tdb) before start of xenstored daemon during the boot (or removal during the shutdown/reboot of the server) as proposed by Ian Campbell during our discussions [1].

Hi All, Was curious if anyone successfully running WinXP HVM (x86) under Xen 3.2.1 with the HAL set to "ACPI Multiprocessor" without using up oodles of CPU time?  Works great with "Standard PC" but would like to get all the CPU cores accessible for XP... -- Daniel Kao Übermind, Inc.

I''m installing a new server, and I want know waht is better: - Install xen from source from xen.org version 3.4.2 ? - Install xen fron apt-get from debian package 3.2.1 ? The server has Debian Lenny. What is correct on production server ? -- Martin _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

We have tested latest xen on VT platform with Intel 915/E8500 chipset.Here is the test summary. Issues: - IA-32 VMX guest will hang when booting on IA-32PAE host with acpi=1 and apic=1.(Bug 594) - Failed to created VMX after tens of VMXs have been created & destroyed on IA-32e.(Bug593) IA-32: Build&Boot SMP xen0 without problem Can bootup unmodified IA-32 2.4/2.6 linux in VMX

Hello Everyone, I am hoping I can get some help with how vCPUs work with weights and caps 1. If I have a domU with 2 vCPUs and a weight of 256, does the weight double (512) or is this 256 time slice across both vCPUs. If the weight does not double, how is it beneficial to have multiple vCPUs? 2. If the domU has 2vCPUs and a cap of 100% how does this work since 100% is a mex of one physical

Hi, What would I need to do to make wine run LotrO on just one core, or How do I set it to use both to test if that helps?

My Dear R buddies, I'm feeling ashamed that I've been running my R program on some servers for a while but do not know exactly how R is working. The servers are chained together using Sun Grid Engine. Each node has 8 quad-core CPUs. I wonder how many cores and CPUs are used by a simple single-thread R program. Thanks a lot. Best wishes, -- ??? Hesen Peng

Hi All, What is the best way to remotely monitor/administer a group of xen domUs across a network? We''re planning to deploy a few H/W servers with paravirtualized domUs. What are the best alternatives? What works and What doesn''t? Share your experiences.

We have asterisk running on a quad processor dell. The kernel has been compiled with SMP. However, asterisk seems to only use 1 processor. 3 of the 4 always stay at 100% idle. Is it pointless to have a multi-proc machine? I was going to buy a new dual 3.6Ghz Xeon server but if nothing will take advantage of the other proc... Perhaps my conception of multi-proc/threaded is warped. If asterisk is

Hello all, does anybody of you have running this version of Ubuntu running as PV domU? I am trying to create domU with that OS using xen-tools from Debian Squeeze with special pygrub role script which installs Ubuntu kernel, creates initrd and grub config. ii xen-tools 4.2-1 Tools to manage Xen

Comparing my last know working configuration with the current one, it appears to be gagging on the new localhost\.localdomain that is in the configuration file.

Hi, I try to start a DomU with xm create endian -c and got the following error message Xend has probably crashed! Invalid or missing HTTP status code. I''ve tested the DomU with nearly the same system at VMWare (Windows) and it works normaly, but on my server I get this error message. I useing gentoo as Dom0. I tried also a gentoo DomU with the same result. Thanks.
