mdadm exim mysql
I installed a CentOS-5 core OS (using --nobase in my kickstart).
For some reason, it included mysql-5.0.22.
When I do "yum remove mysql", it says it will also remove
exim and mdadm for dependencies.
I don't care that exim will be removed, but I need mdadm as
I'm doing software RAID.
But why are these even related? When I do:
rpm -q --requires mysql
neither exim or mdadm is

central logging/analysis
I'm interested in doing centralized logging & analysis of logs from my
CentOS boxes.
I messed around with syslog-ng and it seems like it's a better syslog.
But I noticed most of the "usual suspects" of third-party repo
maintainers (Dag, Axel, etc.) don't include it. Karanbir has an el4
version, but all my boxes are CentOS 5.
I was going to go ahead and roll my own

Help on setting up a PVM
I''m going to set up a PVM on xen-3.3.1 debian-amd64. I need advices
about the best methods to install a fresh debian on it (i.e. how to
choose the kernel for pvm) . I''ve installed xen from sources and only
have one xen kernel in /boot which I''m using for dom0; should I use
the same kernel for domUs?
There is any problem on use vcpus=2; the other vm is an hvm running

disk performance about half in domU? + question about XenSource
Based on some tests we ran, it seems the biggest performance
hit you get from running within domU is from disk I/O. We
did some mysql read and write tests, and for both, our
performance is about half that compared to native. Has that
been others'' experience?
Is there any way to make this better? We are using physical
partitions. In contrast, cpu/memory tests appear to be near

multiple files with same attributes
I''m almost afraid to ask because this probably sticks out
like a sore thumb on the wiki somewhere, and I''m just not
seeing it.
But I have a bunch of files with the same owner/mode. Is
there a way to somehow collapse these, so that all I repeat
is the file name?
Example:

"/opt/test/1":
owner => "jtan",

Migrating DomUs from file VBD to LVM Backend
Hello,
what would be the easiest and fastest way to migrate a file based DomU to a
LVM based DomU. Given that the file contains a partition table + partitions.
I tried with an dummy approach:
dd if=/path/to/file.img of=/dev/volumegroup/logical-volume.
That gives me a logical volume that xm create refuses to use....

Multi domU Xen Box Network Transparent Sound
I have a new development box at home that I am working on.
Currently it has CentOS 5.1 + Xen 3.2 running several domUs.

able to get sound from my domUs and I have been struggling.
I can get some from network transparent sound by using ESD,

distributing selinux policy module
Using audit2allow, I was able to create a policy module for
selinux:
audit2allow -i /var/log/audit/audit.log -M mysqld

I want to distribute this to all my puppet clients.
I can easily put this file in

But even after reboot, although I can see the module listed:

Xen system hang or freeze
Hi all,
This is my first post to the list, I hope someone out there can help!
I am running xen 3.0.3, with CentOS 5.2 based Dom0

Recently I have noticed some complete system lockups on a few different
servers. Neither Dom0 or any of the guests respond to pings, connecting a
keyboard and monitor to the system only shows a blank screen. Nothing is

DHCP and DomUs: not working
I''m trying to get DHCP working with DomU clients. I don''t want to use
libvirtd. There''s a dhcpd on the machine and it works fine for all clients
in the network, but not for DomUs. If I set a static IP on the DomU all
networking for them is fine, so there''s no general networking problem.

building a Xen guest image on straight LVM partitions?
Hello,
When I needed to build Xen guests under Debian I could follow more or
less the instructions in http://preview.tinyurl.com/2oc48r and the
advantage of this approach is that it allows me to setup the Xen guest
directly on the LVM partition without making it consider the LVM
partition as an entire disk with a partition table.
The advantages of this approach are:
1. I can add more LVM's
