I have 5 KVM servers here all running 14.04 - 2 weeks ago one host started to act up with VM's crashing - then this week another host was suffering from terrible internal network delays (bridged NIC) - rebooting the hosts and guests did nothing to resolve the issue - disabling KSM seems to have completely stopped the issues. Disabling KSM was done today ... time will tell if it lasts ...

The more running guests, it happens sooner. Switching back to Saucy kernel is a good workaround.
