CentOS - Dec 2015 - KVM Network (NetworkManager) broken

Hello,

CentOS 7.2

I have a bad big problem with my Server running KVM Client.

I have the most time restarting (reboot) the system a not running network !!!
my interfaces change the name from eth1 to ensX or a Interface is not 
starting?

I mean I have all Situation tested with NetworkManager without NetworkManager 
but the problem exist!!!

I have 4 Interfaces created on install 
	
ens10
ens11
eth0
eth1

this was created on install?

have any a idea what is going wrong with centos

Thanks for a answer,

So that we're clear, is the problem affecting the KVM host, or one of 
the guests running under KVM?

If the problem is affecting the guest, then post its definition (virsh 
dumpxml <guest>).

If the problem is affecting the host, then post all of the 
/etc/sysconfig/network-scripts/ifcfg-* files.
