Support for dnsmasq.d is now in Jaunty's dnsmasq.
Ready to work with whatever libvirt would drop there. |

Binary package hint: libvirt-bin
1. Release:
Description: Ubuntu 8.04
Release: 8.04
2. Policies:
libvirt-bin:
Installed: 0.4.0-2ubuntu8
Candidate: 0.4.0-2ubuntu8
Version table:
*** 0.4.0-2ubuntu8 0
500 http://us.archive.ubuntu.com hardy/main Packages
100 /var/lib/dpkg/status
dnsmasq:
Installed: 2.41-2ubuntu1
Candidate: 2.41-2ubuntu1
Version table:
*** 2.41-2ubuntu1 0
500 http://us.archive.ubuntu.com hardy/universe Packages
100 /var/lib/dpkg/status
3. Expected behavior: I expected the dnsmasq package not to interfere with the running of libvirt-bin.
4. Actual behavior: What happened is that libvirt-bin became unable to provide DHCP services to guest OSes running in a kvm virtual machine.
This is what I see in /var/log/syslog when libvirt-bin is able to start a virtual machine normally:
May 16 08:25:57 bodhi avahi-daemon[5446]: Joining mDNS multicast group on interface vnet0.IPv4 with address 192.168.122.1.
May 16 08:25:57 bodhi avahi-daemon[5446]: New relevant interface vnet0.IPv4 for mDNS.
May 16 08:25:57 bodhi avahi-daemon[5446]: Registering new address record for 192.168.122.1 on vnet0.IPv4.
May 16 08:25:57 bodhi dnsmasq[19217]: started, version 2.41 cachesize 150
May 16 08:25:57 bodhi dnsmasq[19217]: compile time options: IPv6 GNU-getopt no-ISC-leasefile DBus I18N TFTP
May 16 08:25:57 bodhi dnsmasq[19217]: DHCP, IP range 192.168.122.2 -- 192.168.122.254, lease time 1h
May 16 08:25:57 bodhi dnsmasq[19217]: reading /etc/resolv.conf
May 16 08:25:57 bodhi dnsmasq[19217]: using nameserver 192.168.2.1#53
May 16 08:25:57 bodhi dnsmasq[19217]: read /etc/hosts - 9 addresses
This is what I see when dnsmasq is installed:
May 16 08:16:55 bodhi dnsmasq[18482]: failed to bind listening socket for 192.168.122.1: Address already in use
May 16 08:16:55 bodhi dnsmasq[18482]: FAILED to start up
Observations and workaround:
1. It is possible to restore normal functioning while keeping both packages installed:
$ sudo /etc/init.d/dnsmasq stop
After this, libvirt-bin will work properly. However this is obviously not a permanent solution. If dnsmasq is not required to be present on the machine, then the package can be removed and libvirt-bin functionality will be restored (until something else breaks it).
2. It seems the problem is that dnsmasq is started by the OS when booting and then libvirt-bin tries to start it again for its own purposes.
3. I do not know what the proper fix is. Is it stupid to want both dnsmasq and libvirt-bin installed at the same time on the same system? Must libvirt-bin be fixed to handle this situation? I don't know. I installed dnsmasq based on a suggestion that dnsmasq was required for libvirt to provide DHCP services to guest OSes but apparently only dnsmasq-base is required for that. So the information I got was erroneous but it does not change the fact that the current packaging specs do not prevent users from shooting themselves in the foot. |
============ SRU justification ===========
Impact: libvirt fails to bring up virbr0 when dnsmasq is installed
Development fix: install a dnsmasq.d file to prevent the system-wide dnsmasq
from binding to virbr0.
Stable fix: same as Development fix
Test case:
virsh net-destroy virbr0 || true
sudo apt-get purge libvirt-bin
sudo apt-get -y install dnsmasq
sudo apt-get -y install libvirt-bin
Regression potential: There should be none, since we are simply telling the
system-wide dnsmasq (if any) not to bind to the virbr0 which our own dnsmasq
instance will bind to.
