[CentOS] hostname on centos 7.1

[Martes]

Greetings everyone.

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.)

Respectfully, 

Martes G Wigglesworth

hostnamectl set-hostname --static c7.msgnet.com  


Without the static option, I think it leaves out the periods in the name.
