Just to clarify... I have just tested the immediate change taking effect, after reading the page listed in the other reply. For some reason I was able to see immediate change on my vms, however, now that I try it on the Host, it does not persist. So maybe when I was setting things up, I actually flashed the vms. (I can't remember, but the change was done, and I immediately typed `hostname` and it appeared to have taken immediate effect. However, this is not the norm, as I have just discovered.)

I have some CentOS 7 VMs running on the system for which I just made the inquiry about the kworker problem, and I was able to institute immediate change of hostname by updating the /etc/hostname file. I have network manager running on the host, as well, and it also has the name populated in this file. When I make the change in /etc/hostname, it takes immediate effect, and persists across reboots, just as with /etc/sysconfig/network prior to RHEL/CentOS 7. If my input is out of context, then I apologize for the confusion. (I have vlans attached to the gigabit Ethernet cable, which is used to service the exposed VMs, and I use the wireless adaptor for all other internet and lan usage, hence my use of network manager on the desktop being assumed to be relevant to this inquiry.)
