[libvirt] dnsmasq, dhcp - bug or feature
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello list, I have network definition like this: <network> <name>default</name> <uuid>5539715b-ae89-c15c-aa2e-2f5a7afd55b8</uuid> <forward mode='route'/> <bridge name='virbr0' stp='on' delay='0' /> <ip address='10.117.9.1' netmask='255.255.255.224'> </ip> </network> and I would assume it means DHCP is off. Even virt-manager claims it's off, yet dnsmasq gets started every time. And what's "worse", it's giving away IP addresses. So, I'm wondering if it's bug or feature or have I missed something? :o) libvirt version is 0.8.4 as I haven't upgraded to 0.8.5 yet.

Hello list,
I have network definition like this:
<network> <name>default</name> <uuid>5539715b-ae89-c15c-aa2e-2f5a7afd55b8</uuid> <forward mode='route'/> <bridge name='virbr0' stp='on' delay='0' /> <ip address='10.117.9.1' netmask='255.255.255.224'> </ip> </network>
and I would assume it means DHCP is off. Even virt-manager claims it's off, yet dnsmasq gets started every time. And what's "worse", it's giving away IP addresses.
It always has to be started so that guests get the DNS service from it. It should have the DHCP service disabled though if you don't give any DHCP lines in the XML.

Hello Daniel, thank you for your reply, although it gave me couple minutes to figure it out; that dnsmasq serves also as an DNS forwarder. Well, I haven't thought about this one, because we have everything external. Providing such option would be great; dnsmasq optionality; yet I'm pretty sure it would complicate (or even break) a lot of other things. Ok, at least one mystery got explained. :o) Thanks, Zdenek - -- Zdenek Styblik Net/Linux admin OS TurnovFree.net email: stybla@turnovfree.net jabber: stybla@jabber.turnovfree.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkyY680ACgkQ8MreUbSH7ik17gCfbEq6Z2bSE8nHmqzoamp/RxoZ dFMAn3Ryhv1wd4UmythbKEXa5rmYhDXE =5c0W -----END PGP SIGNATURE-----
