Hello
I'm currently using Linux kernel 3.13.0 (Ubuntu Linux 14.04 with
latest updates). KVM works in general but I noticed a number of small
bugs. E.g. after suspending/resuming a system time is different on host
and guest systems (FreeBSD 10.2). Also when guest system consumes 100%
of its CPU, htop on host system shows that utilization is 100%, but in
guest system it shows only about 33%. Etc.
Is it worth trying to upgrade Linux kernel to say 4.5? Does an upgrade
usually solve some problems with KVM or more likely I will just waste my
time? So basically I'm asking what is considered rule of thumb here.

None of the bugs sound like something that would be fixed (in fact they
might even be FreeBSD bugs). However, upgrading to a recent kernel is
generally a good thing to do before reporting a bug.
