I''m trying to configure GRUB to allocate fixed amount of dedicated memory to dom0, according to this best practices thread (http://wiki.xensource.com/xenwiki/XenBestPractices | "Xen dom0 dedicated memory and preventing dom0 memory ballooning "). When I reboot, dom0 has the fixed amount of memory as it was configured, but neither xm info shows the rest of memory available

I have installed SuSE 10 SP2 Xen server. There were two images under /boot - vmlinux-2.6.16.60-0.21-xen and xen-syms- 3.2.0_16718_14_0.4. what are these two images? I know I am booting on the first which is the dom0, what is the second one, is it the hypervisor? where can I identify which process is the hypervisor? _______________________________________________ Xen-users mailing list

Hi, I recently compiled a Xen-4.0.1 and pv-ops Dom0 2.6.32.27 kernel from JF''s tree.Where my hypervisor could not boot and unfortunately the system is rebooting so frequently that I am not able to note down the error messages on a paper and pencil.So now I am planning to go for a non pv-ops Dom0.I am not clear as what should be the approach? I have been Googling it every now and then and

I am working on a security tool that monitors various components (IDT, SSDT, etc) of a domU using VM introspection. Currently, we''re using a polling method to monitor these in-core structions. We would like to be able to use a blocking method instead. I.e. specify "interesting" memory ranges and then wait until they are modified. How can I get the hypervisor to alert a

Hi folks, I hope this is the right place to ask - if not I can switch to the CentOS mailing list. I am running GITCOs 3.4.3 hypervisor with original RHEL5.5/CentOS5.5 kernels in dom0 and domU. I have phenonema I want to get rid of (like time running wild - really wild). So I am looking for a way to compile a kernel with all CentOS refinements/backports/additions and xen 3.4.3. I have

I started a new thread because this not a pv-ops dom0 anymore. I''m running Andrew Lyon''s 2.6.31-4 patches for a non-pv-ops kernel. Got it again, after issuing "poweroff" from the domU.

Package: xen-hypervisor-4.1-amd64 Version: 4.1.3-7 Severity: important Tags: patch Dear Maintainer, The PMU may be enabled on the Dom0 although the needed MSRs are not accessible, causing at least major noise on the xen messages ring buffer. I suspect there might also be a performance decrease, because the MSR write is trapped by Xen. Once the PC is in that state, a reboot won't help. This

Hi All, After digging through the xen wiki, the recommendation I have found so far for first time virtualization testing of XEN is to use Centos. Do I get to choose which XEN hypervisor version I want to run?...e.g if I want the latest (XEN 4.1) At the moment I am using a liveCD - feeling my way around Linux environment (newbie here as well)... Any pointers to set me in the right direction

I just discovered that my xen hypervisor only believes that it has 3199 MB of memory, when there are 4GB inside the computer. I don''t know how long this has been this way, but I do not know how to try and force the hypervisor to realize how much memory it has. Any ideas how I can accomplish this? I am running CentOS 5 (RHEL 5), kernel 2.6.18-53.1.4.el5xen, x86_64, xen 3.0.3.

Modify the cpufreq ondemand governor so that it can get idle and total nsecs from the Xen hypervisor.  Xen uses nsecs to measure idle time, while Linux uses ticks. Other than accounting for that difference, use the same algorithm to calculate idle time as Linux does.

Hi Jan, I was wondering if we should not let the code fall through and clear all registers to zero but rather clear just the one bit we care about? My concern is that a future Intel revision may expand this function and return other information besides that XSAVEOPT, which would then be wiped out by the fall-through code. I''m thinking something like this. Let me know if I have

Good morning, I am working on a project that does some system profiling at hypervisor level. I want to send some data from hypervisor to Dom0, and each time the data to be sent are quite small: only 8 bytes. I imagine that each time after sending data to Dom0, hypervisor needs to somehow notify Dom0 about the data it has just sent. I am studying Xen and it looks like I can do it in 2 ways: 1)

Hi All, Debian Lenny, Xen 3.2.1 Apologies if this has been covered many times before, but I''m unsure how to go about this. I want to obtain stats from my dom0, IO, cpu etc over time to see if I''m getting any load peaks or if my hardware could handle more domU''s. I''m thinking of something similar to sar which gives you 15 minute averages across the day. I

Hello, my name is Viktor. I use kernel-2.6.38.5 as dom0. I can''t get access to console dom0. There is a blank screen after xen-4.1.0.gz loading. But dom0 is loaded and I have got it from ssh and it works fine. I just see nothing at monitor screen. Why? May be I have error in my grub.conf settings, please help!

Hi all, I would like to know how to debug xen. To give some more informations, I would like to explain why I''d like to do this. I''ve compiled xen from source (3.1.x/unstable) and installed it on Debain etch. Furthermore I''ve installed 2 DomU, one HVM (Win2k3) and one EFW (Endian Firewall, RH-based 2.6.9-55 kernel). Both DomU''s are running fine for about 15

Hello, I''m running a standard Debian Etch Xen server for testing. Today I ran a Debian update and it installed some new kernel-related packages. The install scripts said something about deleting unused symlinks, but I was in a hurry, so I can''t remember exactly. Now I''ve the problem that the server will not boot any more. After loading the hypervisor, the system
