Title: KVM guests getting slow by time Status in “linux” package in Ubuntu: Incomplete Status in “qemu” 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.
