This goes on every half an hour.

What does this mean.

I have Centos 5, with KVM virtualisation.

Your DHCP clients are renewing their DHCP leases.

Is it perhaps the lease time on the dhcp server side of things? Have a look in the manual (I think -F and/or -G options).

This is server with static IP connected to the internet.

I have one virtual host via bridge that gets its IP in static way, and one virtual host that gets dynamic IP.

Why does the dynamic host call for new lease every 30 minutes ?

Check your dnsmasq config file.

Everything is grey (with #).

There is only one active line:

conf-dir=/etc/dnsmasq.d

And this dir is emprty.
