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...
[root@C5 ~]# service dnsmasq status dnsmasq (pid 3776) is running... [root@C5 ~]# 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:
[root@C5 ~]# 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.
