[Bug 1341195] Re: KVM guests getting slow by time
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 ...

Title:
KVM guests getting slow by time
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
There is a post with very similar symptoms on serverfault:
http://serverfault.com/questions/609881/windows-server-2012-on-kvm-on-
ubuntu-14-04-runs-well-for-a-while-and-then-slows/612084#612084
Basically all kind of KVM guests are getting slow by time, both windows or linux. The more running guests, it happens sooner.
Switching back to Saucy kernel is a good workaround.
