Thanks for the reply Kai.
I will try to clarify...
I originally built the centos 5 system with xen - but I was having
various network problems. I found that if I booted the alternate "non
xen" kernel - I had fewer problems. I had no pressing need for xen - so
I changed the default boot kernel to be the non-xen kernel - so I assume
I am now NOT running xen. However - dnsmasq still appears to be
running... Here are some of the commands you suggested...
[EMAIL PROTECTED] ~]# service dnsmasq status
dnsmasq (pid 3776) is running...
[EMAIL PROTECTED] ~]# ps ax|grep dnsmasq
3776 ? S 0:00 dnsmasq --keep-in-foreground --strict-order
--bind-interfaces --pid-file --conf-file --listen-address
192.168.122.1 --except-interface lo
--dhcp-leasefile=/var/lib/libvirt/dhcp-default.leases --dhcp-range
192.168.122.2,192.168.122.254
25474 pts/2 S+ 0:00 grep dnsmasq
This looks to me like some xen stuff is running - in particular the
192.168.122. subnet looks a bit xen-ish.
But I am confident that the "non xen" kernel is running:
[EMAIL PROTECTED] ~]# uname -a
Linux C5.aardvark.com.au 2.6.18-53.1.14.el5 #1 SMP Wed Mar 5 11:37:38
EST 2008 x86_64 x86_64 x86_64 GNU/Linux
I guess that there must be lots of things I don't understand. It is not
clear to me whether I am using xen or not - though I am not intending
to...:-)
I notice that libvirtd is running - and is set to run on boot. Should
this be the case when running the non xen kernel?
Should I set libvirtd to not start on boot. This might get rid on
dnsmasq - but is it a safe and good thing to do in my case? Presumably -
if I want to use xen at some future date - I will need to change kernels
- and restart libvirtd.
Is there anything else I need to prevent from starting to eliminate all
traces of xen?
Thanks
Richard.

In my startup scripts - dnsmasq is set to "not
start on boot" so I thought there was no problem - but I find that in
spite of the startup script - dnsmasq appears to be running.
What did you do?
service dnsmasq status
or
ps ax|grep dnsmasq
?
dnsmasq would indeed be running, although it's not configured to start,
*if* you were using xen, because libvirtd would start it. It's not clear
if you are using xen or not.
