CentOS - Aug 2015 - Libvirt resume guest startup issues centos 7

Here is the relevant log snippet:

journal: libvirt version: 1.2.8, package: 16.el7_1.3 (CentOS BuildSystem
<http://bugs.centos.org>, 2015-05-12-20:12:58, worker1.bsys.centos.org)

journal: failed to connect to monitor socket: No such process

journal: internal error: process exited while connecting to monitor:
((null):1937): Spice-Warning **: reds.c:3036:reds_init_socket:
getaddrinfo(127.0.0.1,5900): Address family for hostname not supported

qemu-kvm: failed to initialize spice server

If I remove graphics devices from the VM it saves/resumes properly on host
restart.

https://bugzilla.redhat.com/show_bug.cgi?id=721350

I feel like this is an issue of libvirt starting before networking, but I am
a fish out of water with systemd.

Any thoughts?

Are you using the "network" or "NetworkManager" service to
configure
your network devices?

Likely, if that is how they are out of the box.

I've looked at this a bit... But, bear in mind that I don't use Spice, 
so everything I say may be wrong.

I don't think libvirtd is starting before networking, regardless of the 
service.  However, if you'd like to test that theory, you can copy 
/usr/lib/systemd/system/libvirtd.service to /etc/systemd/system and edit 
it.  Replace the line "After=network.target" with 
"After=network-online.target", then reboot.  See if that affects the 
problem in any way.

The problem looks vaguely like the server is trying to use an IPv4 
address (127.0.0.1) and an IPv6 address family.  I'm not sure why it 
would do that.  Were there any specific directions you followed to set 
up Spice?

I don't think this bug is relevant, as it results in a return value of 
EAI_NONAME.  In your case, getaddrinfo returns EAI_FAMILY.

Same *exact* error with VNC.

Will try, but not until Wednesday / Thursday PM.

====================Install Centos 7 x64 minimum.
[left as default]
vi /etc/sysconfig/network-scripts/ifcfg-eno1
[change onboot=yes]
service network restart
yum update -y && yum install nano logwatch ntpd ntpdate &&
reboot
nano /etc/hostname
yum group install 'Virtualization Host'
chkconfig libvirt-guests on
yum install virt-manager xauth
nano /etc/sysconfig/network-scripts/ifcfg-br0
[delete auto created virtbr0]
Reboot
[create vm with defaults - centos 7 x64 minimal]
virsh autostart centos7.0
[reboot]
[debug, pull out hair, email centos list, remove ipv6, remain puzzled]

This and its linked tickets is where I figured to disable IPv6.
