Hi,
I have the following messages in dmesg output, are they indicating
a cpu issue, or are they just indicating that because linux is running
in a vm under windows, and hence sharing the cpu cores with windows that
windows was using core 7 at the time the process checked?

It's possible that Windows was using that core for long enough that the
kernel thought that it wasn't getting enough time. Did you share all
the cores with the VM? That's not a good idea.
