Hi, list, A VMM provides a VMCS for each VM. How does the VMM assign system resources for each VM? For example, in a multi-core environment, how can I enable the VMM to run, say, on a two-core intel''s processor while I am able to force a VM to execute only on a specific core upon initializing the Guest OS ? that is to say, how I can assure the VM to believe that there is only one physical

The unstable tree now includes support for SMP guests, i.e. domains which run on multiple cpus. SMP guests can use between 1 and 32 virtual cpus, even if the machine has fewer physical cpus. The code is highly experimental and performance will improve over time. To use SMP guests: - enable option CONFIG_SMP in the Linux 2.6 kernel config - dom0 will boot with upto the number of physical cpus in

I have a 2 way machine. Soliciting folks opinion on whether it makes sense to smp enable DOM0 so that IO handling can be balanced over both CPU''s... Opinions?

Existing credit scheduler is not power aware. To achieve better power saving ability with negligible performance impact, following areas may be tweaked and listed here for comments first. Goal is not to silly save power with sacrifice of performance, e.g. we don''t want to prevent migration when there''re free cpus with some pending runqueues. But when free computing power is

In Xen''s 3.0 documentation is stated: "f you are running IO intensive tasks, its typically better to dedicate either a hyperthread or whole core to running domain 0, and hence pin other domains so that they can''t use CPU 0." http://tx.downloads.xensource.com/downloads/docs/user/#SECTION03400000000000000000 I am mostly running web servers, so it''s IO

Hi, I'm currently thinking of putting more functionalities to Linux server box. Major is Asterisk, but would also like to add video surveillance, home automation and limited (for only domestic up to 4 users) web, file and mailserver apps. I know there are problems running Asterisk with other such apps on same machine - but wonder if I can take advantage of dual processor machine in this

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.

If you are using the Express versions of Visual Studio, the Platform SDK(windows.h) is a seperate install that you have to download.

Hi there, I'm currently using CentOS 4.3 (Server edition) in a HP DC 5100 with the IntelR 915GV chipset, powered by a PIV 3.0GHZ. Now I'm facing a problem, with memory. I got myself 4GB of memory, the system bios detects it correctly, but in Linux can only see around 3.5gb memory. With the default kernel-smp (I use hyperthread) or with kernel-hugemem , I have the same results.

Hello I can save you a lot of time, and tell you that it wont work. It does hold some registration information in the asterisk database, but most of the information is kept internally in Asterisk.

HI, Is it possible to specify CONFIG_PREEMPT_RT=y in the Dom0 kernel? It seems that it is forbidden as it is not a menu option in make menuconfig and gets removed if I manually add it to the .config. I want to run a sound server on Dom0 and am having problems with xruns at present, so need to be able to run a preemptive kernel. Thanks, Chris _______________________________________________

Hi, I am trying to figure out why a new machine is running my R script so slowly. The script was developed on a Linux , dual 2.8 xeon processor machine with 4GB ram. On this machine, the script runs in about an hour (it creates lots of multilevel simulations). While running, 100% of a single processor (50% of dual processor) is used consistently during the entire run, about 800 MB of ram is

after shutdown many domu, the memory is not release to dom0, before:  host: 8g phy memory 16g swap (4g used) dom0: 600m domu: consumed all memory, no new domu could be created after shutdown many domu:  host: 8g phy memory 16g swap (4g used) dom0: 600m domu: 2g why memory of dom0 is still 600m? how to release more to dom0? pls advise.
