libvirt users - Nov 2010 - libvirtd & dnsmasq

libvirtd is starting dnsmasq! This is on RHEL5.5

I don't see it mentioned in /etc/init.d/libvirtd or /etc/libvirt/* or
/etc/sysconfig/libvirtd

 4337 ?        S      0:00 /usr/sbin/dnsmasq --strict-order
--bind-interfaces --pid-file=/var/run/libvirt/network/default.pid
--conf-file=  --listen-address 192.168.122.1 --except-interface lo
--dhcp-range 192.168.122.2,192.168.122.254 --dhcp-lease-max=253

How can I properly disable this funcationality? (I'm running dnsmasq for
other purposes on the host, and the libvirtd incantation conflicts).

Thanks.

It's because of this:

---
postinstall scriptlet (using /bin/sh):
/sbin/ldconfig

# We want to install the default network for initial RPM installs
# or on the first upgrade from a non-network aware libvirt only.
# We check this by looking to see if the daemon is already installed
/sbin/chkconfig --list libvirtd 1>/dev/null 2>&1
if [ $? != 0 -a ! -f /etc/libvirt/qemu/networks/default.xml ]
then
    UUID=`/usr/bin/uuidgen`
    sed -e "s,</name>,</name>\n 
<uuid>$UUID</uuid>," \
         < /usr/share/libvirt/networks/default.xml \
         > /etc/libvirt/qemu/networks/default.xml
    ln -s ../default.xml /etc/libvirt/qemu/networks/autostart/default.xml
fi

/sbin/chkconfig --add libvirtd
---

I put in a request to get it removed.

Yeah.  When libvirt is installed, it creates a default NAT network for guests to
use.

But, it's not hard to configure a system with dnsmasq already installed, to
not have it get confused by libvirt. :)

There's a wiki page (very short) with the two lines to change here:

  http://wiki.libvirt.org/page/Libvirtd_and_dnsmasq

Hope that helps. :)
