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.
