Title:
KVM slowed down with aparently no reason.
Status in linux package in Ubuntu:
Confirmed
Bug description:
The server was working perfectly for months, suddenly (yesterday) it
started to slow down the VMs and now I noticed that the CPU Use is
very high and a lot of messages on the dmesg.
I checked if it had any kernel update, but the latest update were from
last year.
I will try upgrading the server to 16.04 in a few days if I can't
solve the problem.
