yes, i've used the same virtual machines in both cases. everything is the same except the driver. I switch from virtio to e1000

 glance image-update --property hw_vif_model=e1000 <image-id>

Now I relaunch the virtual cluster and everything works perfectly fine. I've tested with 5 times the load but it doesnt crash anymore.

I have tested the same cluster configuration with virtio on Centos 6.5 kernel 2.6.32-431.17.1.el6.x86_64 #1 SMP Wed May 7 23:32:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux and that crashes too.
I will test the centos version with e1000 and see if that works.
