This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
Comment 3 Cole Robinson 2012-05-28 19:51:56 EDT
From your logs, it looks like you are using libvirt's default virtual network. This mode relies on non persistent iptables rules added when libvirtd is started. The problem is likely that iptables was restarted, or another tool like system-config-firewall made changes to iptables that wiped out libvirt networking rules. This is a long known issue unfortunately :( Work has already started for F18 timeframe to have libvirtd work with firewalld to store these rules in some persistent manner, effectively fixing this issue. But it won't ever make F15 (which is end-of-life in a month). That said, I'm just assuming that's the issue you were hitting :) If you think I missed something and you are still encountering this on F16 or later, please reopen this report.
