Hi Daniel,

I'm very surprised. dnsmasq is not listed in the dependencies of libvirt as far as I know. I was guessing that it's a "nice to have" package, to enable DHCP IP distriPid: 2616, comm: libvirtd Tainted: P         2.6.25.20-113 #1
bution to guests. But even if it doesn't exist, I shall normally be able to assign static IP addresses manually to my guests.

So if the system crashes due to dnsmasq, I would call it a bug instead.
Nevertheless, I'll try to compile this package for our distro and see what happens.
I'll keep you posted, thanks again a lot for your interest.

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

The DEBUG output shows in the last lines:

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
