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:


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?

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"?

I removed dnsmasq startup from the runlevel, now it works fine. I have seen dnsmasq errors for a long time, but I didn't really care too much about, as I don't need dnsmasq and the warnings didn't stop libvrit from working. I think I'll just deinstall dnsmasq.

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


# ls /usr/local/var/lib/libvirt/dnsmasq
