+++ This bug was initially created as a clone of Bug #713728 +++ Description of problem: When editing a network in virsh ('net-edit default', 'net-destroy/start default') to e.g. add a new MAC/IP static address combo, /var/lib/libvirt/dnsmasq/default.hostsfile seems to lag one "version" behind, i.e. carries combos only from the previous edit. To make the current ones effective, changing an unrelated one (e.g. change a hex digit from upper to lowercase) then destroying/restarting the network helps (the unrelated change is only effective on the next change though). I haven't found this issue in RH/Fedora Bugzilla, but googling gave me an open ticket on Launchpad for Ubuntu: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/584910 Version-Release number of selected component (if applicable): libvirt-0.8.8-4.fc15.x86_64 libvirt-client-0.8.8-4.fc15.x86_64 libvirt-python-0.8.8-4.fc15.x86_64 How reproducible: Reproducible Steps to Reproduce: 1. 'net-edit default', then add a new static DHCP mapping to the default network (e.g. <host mac='FF:FF:EE:EE:DD:DD' ip='192.168.122.254' />) 2. 'net-destroy default' 3. 'net-start default' 4. 'grep FF:FF:EE:EE:DD:DD /var/lib/libvirt/dnsmasq/default.hostsfile' Actual results: (nothing) Expected results: FF:FF:EE:EE:DD:DD,192.168.122.254 BTW, I noticed that destroying/starting the network makes it unusable on running guests without rebooting them (they don't ping, restarting the network service in the guest or equivalent doesn't help). Is that expected/intentional or are there ways to add a new static MAC/IP address combo without having to reboot other running guests? --- Additional comment from nphilipp on 2011-08-03 09:13:50 EDT --- Ping? --- Additional comment from crobinso on 2011-08-03 10:23:30 EDT --- Laine, any thoughts? --- Additional comment from laine on 2011-08-03 16:34:58 EDT --- The problem is that when an active network is re-defined, the new data is stored in network->newDef, but the code that builds the new hosts files uses network->def (the old version of the config). If the network is inactive at the time it's redefined, then the new data is stored directly into network->def, and it takes effect immediately. I just posted a patch upstream to fix the problem: https://www.redhat.com/archives/libvir-list/2011-August/msg00181.html
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
F14 is EOL, so closing this.
And as indicated above, it was fixed upstream, so is in later releases of Fedora (starting with F16)
