My suspections were correct. The dnsmasq does not have anything to do with
the crash. I installed the dnsmasq package and it works fine:

 2616 pts/1    S+     0:00 /usr/sbin/libvirtd
 2637 pts/1    S+     0:00 dnsmasq --keep-in-foreground --strict-order
--bind-interfaces --pid-file  --conf-file  --listen-address 192.168.122.1
--except-interface lo --dhcp-leasefile=/var/lib/libvirt/dhcp-d

However, I still have the crash in the dmesg output, as before, errors like:



sysfs: duplicate filename '0' can not be
created

------------[ cut here

The DEBUG output shows in the last lines:

DEBUG: util.c: virExec (dnsmasq --keep-in-foreground --strict-order
--bind-interfaces --pid-file  --conf-file  --listen-address 192.168.122.1

DEBUG: lxc_container.c: lxcContainerAvailable (clone call returned Cannot
allocate memory, container support is not enabled)

I still suspect the compiler flags. Any suggestions? What about this last
DEBUG message regarding the container support?

Thanks a lot &  Best Regards,

Emre
