Hi, I've upgraded to 0.9.0 today on my Debian Squeeze boxes. Everything went fine, expect on one node (and only on that one, although the setup is identical), the first start of libvirtd since boot (and again, only that start) crashes with SEGV. Here are traces from gdb: http://pastebin.com/DiZrw0S5 http://pastebin.com/eacJRv07 If I delete the PID-file and start libvirtd again, it works fine. It doesn't seem to matter when the first start since boot happens, I've deactivated startup of libvirtd at boot time. Any ideas or further infos needed? thanks & regards, thomas -- libvir-list mailing list libvir-list(a)redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

Aside from Michal's fix to the error *recovery*, the more interesting question is why this is now failing. The bits of system log we can see in the pastebin shows that dnsmasq failed with an exit code of 2. From the manpage, this means: 2 - A problem with network access occurred (address in use, attempt to use privileged ports without permission). Do you have a system instance of dnsmasq already running? (perhaps it's already listening on all interfaces) Can you send the output of "dnsmasq -v; ps -AlF | grep dnsmasq"?

Also, does the directory /usr/local/var/lib/libvirt/dnsmasq exist?

I think I'll just deinstall dnsmasq. Are you sure you want to uninstall dnsmasq, and not just disable it in the system config? If you uninstall dnsmasq, libvirt will fail to start the virtual networks - it uses dnsmasq to provide DNS for those networks even if you don't specify a dhcp range or hosts.

Do you have a system instance of dnsmasq already running?
