@Serge I did upgrade my kernels yesterday evening both on hypervisors and guests so now I'm running 3.2.0-25-generic on hosts and the same kernel version but virtual for VMs. Same problem today morning, some VMs dropped out. I'm actually using virtio everywhere. I'll try to test another one and keep you in touch asap. I also tried to run a VMs with the generic kernel (not the virtual one) and I'm facing the same issue. Serge as I'm building this new plateform I can say they there is no traffic at all on my VMs exept 2 guys testing some java stuffs. I almost thinking that VMs drop out when there is not enough traffic on nics...

Serge, ne2k_pci seems to drop the link when generating some traffic (only tested on 4 VMs). e1000 seems have to same problem as virtio, dropping connections without traffic ... What else may I try ?
