CentOS virt - Aug 2016 - No network using qemu-kvm-ev-2.3.0-31.el7.16.1

Hi all,

 To do some tests, I have installed a new CentOS7 host (fully patched) using
qemu-kvm-ev-2.3.0-31.el7.16.1 instead of qemu-kvm's default package. And I
have problems with network inside my guests.

 All guests can ping to CentOS host but nothing more: can't resolv dns
names, can access via tcp to other hosts, etc ... Using same config on other
CentOS7 host, but using default qemu-kvm package instead of
qemu-kvm-ev-2.3.0-31.el7.16.1, all works ok.

 What am I doing wrong? Or is it a bug?

Thanks

Martinez,
Any more config you have checked for DNS resolution related? You can ping to
other host in the network right?
