Package: xen-system-amd64 Version: 4.1.4-3+deb7u1 Severity: normal The xen kernel detects 3GB of memory instead of the full 4GB. When using the "normal" kernel 4GB is detected. On boot the 4GB is detected: root at ams-tc1-xen27:~# dmesg |grep Mem [ 0.000000] Memory: 3226132k/4980736k available (3426k kernel code, 788180k absent, 966424k reserved, 3312k data, 576k init) But only

Hello, To thank you for telling me if this message is not posted on the good list. After installing Xen 4 on a workstation HP Z400, the hypervisor is extremely slow, both on a Fedora machine on a Debian Squeeze, whether in 32-bit or 64-bit version. Unable to install a DomU. The problem seems to come from the hardware configuration of the HP Z400 - Xeon - W3550-4 processors - 16 GB of

Hi All, I have gone through threads related to throughput issue in this list. Found few similar issue, but could not get the solution. So looking for some advice from group. I am trying to use the samba to access a USB disk connected to our evaluation board which has xtensa core running at 400 MHz. Samba 3.5.x is running on the board. We are getting below throughput as tested with the

Hello. I plan to use OCFS2 + DRBD for email server. Problem: I use "seeker" for testing http://www.linuxinsight.com/how_fast_is_your_disk.html And get this: Results: 65 seeks/second, 15.23 ms random access time Then I do rm of many files - it fals to 10 seeks/second and performance is terrible. What can I do to increase it? What`s wrong? Below is many info. What we have: Debian

This is a continuation of my previous posts about improving write perf when trapping millions of small writes to a gluster filesystem. I was able to improve write perf by ~30x by running STDOUT thru gzip to consolidate and reduce the output stream. Today, another similar problem, having to do with yet another bioinformatics program (which these days typically handle the 'short reads' that

Good Day All, Today I looked at the dmesg log and I notice that the following messages regarding mtrr_gran_size/mtrr_chunk_size. I am currently running CentOS 6.3 and I installed CentOS 6.2 and 6.1 and I was seeing the same errors. When I installed CentOS 5.8 on the same laptop I do not see these errors. $ lsb_release -a LSB Version:

Has anyone seen this issue? We're running containers under CentOS 7.2 and some of these containers are reporting incorrect memory allocation in /proc/meminfo.

As I mentioned, I got the instances to launch... but they're only taking HugePages from "Node 0", when I believe my setup should pull from both nodes.

Hello, Last night I upgraded a server to CentOS 5.2. The server has 16GB of RAM. Now that it's running 2.6.18-92.1.6.el5xen only 8GB is reported to exist. # cat /proc/meminfo MemTotal: 8818688 kB MemFree: 3730124 kB Buffers: 202004 kB Cached: 4086788 kB SwapCached: 0 kB Active: 1551480 kB Inactive: 2958196 kB HighTotal: 0 kB HighFree:

The host server halts upon shutdown of 126000mb domU (64-bit SLES10). It booted fine and was able to run kernbench. However, during shutdown the host crashes. Host is Unisys ES7000 host with 32 processors and 128gb memory using x86_64 SLES10 with xen-unstable c/s 15080. Reducing the memory allocation for the domU to 124000mb works fine. My guess is that specifying 126000 does not leave
