Hello, I''ve seen from time to time where a domU using heavy disk I/O can slow down an entire server (including all other domU''s and dom0). Is there a way to schedule or limit this in Xen 3.0.3? Thank you, Brian ** _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi Ive recently created a DomU machine, when I run the xm create -c command however the machine only boots to a certain point. Then stops....see below root@gangster:/etc/xen# xm create -c hudson Using config file "./hudson".

Hey All, I've been working on trying to get asterisk to play nice under Xen and I've run into a bit of a road block. I'm not using any hardware stuff only ztdummy. First I had issues getting ztdummy to work but that was solved by recompiling the xenU kernel to have CONFIG_CRC_CCITT=y which it was missing. Now ztdummy is seen fine in the virtual machine though when I run

Hi Xen-users, I am trying to boot of my fist guest domain. The below attached message was thrown on the screen. I am not quite sure that the below information is sufficient to root cause the issue. Where do i look for additional logs to root cause the issue. Appreciate any info that you think might be useful. Thanks, Karthik xm create -c guest1.conf vmid=2 Using config file

Hi list ! We have a very busy webserver hosted in a clustered environment where the document root and data is on a GFS2 partition off a fiber-attached disk array. Now on busy moments, I can see in htop, nmon that there is a fair percentage of cpu that is waiting for I/O. In nmon, I can spot that the most busy block device correspond to our gfs2 partition where many times, it shows that

Hello, i will describe my approach 1) I have downloaded Centos5-64bit xen image from jailtime.org 2) I have created own swap image with 512MB file size 3) I have used same as dom0 kernel 2.6.18-53.1.19.el5xen 4) I have mounted my image file and copied /lib/modules/2.6.18-53.1.19.el5xen 5) I have created custom ramdisk for domU with mkinitrd --with=xennet --preload=xenblk

Anybody sucessfully got stable 1000Hz clock without Digium harware and kernel 2.6? We need to consult some peoples how to clock asterisk stable with exactly 1000 Hz without much kernel/drives patching/tweaking. Some test results we made so far: 2.6 with digium card - stable 1000 Hz. 2.6 with ztdummy - uses RTC and the clock is 1024, not 1000. 2.6 with some Realtime kernel patch - provides stable

Friends, I'm having severe problems with zaptel timers on Intel Dual Core systems with SMP code enabled. Ztdummy, zaptel connected to Digium TDM or PRI cards - all ends up with large timer probems - zttest going down to 50% accuracy on some systems, even to -1 on ztdummy systems and voice quality is no more. A restart is the only way to get back to a working system. We're only

Hello, I am trying to boot a FC6 domU on Xen 3.2 (compiled on a FC6 system). After compiling Xen 3.2 successfully on FC6 and making the ramdisk, I modified the conf.grub as shown below.

Hello everyone, I''m quite a newbie with Xen and I''m currently having an issue. I run Xen 4 on Debian Squeeze x64 and I''m trying to build an OpenFiler DomU from the Xen domU filesystem tarbal they provide (See http://www.openfiler.com/community/download/). I downloaded the tarball and run ''tar xzpvf /root/soft/openfiler-2.3-x86_64.tar.gz'' to extract

Hello. I am hoping someone can help with a problem I am having. I am running the Windows folding at home client through wine. This app is very load intensive and performs many scientific calculations. It consumes 100% of all six cores in my system. However, I run it with a "nice" level of 19 so that it only uses idle cycles. Unfortunately, with this setup, my system consistently

Currently, if you are running CentOS-4.x on a Vmware box you end up with time skew problems. The main fix has been using a set of recompiled kernel that has a HZ that is more fitting with what Vmware expects (eg 100 hz). The 4.7 kernels look like they will not need this: http://jons-thoughts.blogspot.com/2008/04/rhel-and-vmware-time-skew-problems.html Well, I've gotten quite the number of

Greetings- I'm running some USB DAHDI hardware on a system with a tickless kernel. The audio quality is quite poor. Could the tickless kernel be to blame? If so, when recompiling a kernel that is *not* tickless, is there a recommended KERNEL_HZ value? IIRC, older kernels used to be 1000, but newer ones are 250. Thoughts? --Tim

Hi all I was reading through Xen 3 user manual and saw this tap:aio should be used instead of loopback...

I am having an issue getting a DomU to boot properly. There is never any indication of a stop error or kernel panic, it simply hangs after "Starting crond [ OK ]" and never continues.

Hi, I found one weird thing: I heard RAMDISK is not required for domU, but it seems I have to add RAMDISK to my domU config file, otherwiese the domU will hang up when it is booting. Please see the message below, the domU booting hangs up after "Continuing..." Does anyone have any clue for this issue? BTW, xen-friendly glibc is already installed. Thanks, Liang ---Begin of domU
