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
, 2015-05-12-20:12:58,

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(,5900): Address family for hostname not supported

qemukvm: failed to initialize spice server

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

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

Any thoughts?

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

    # for i in /etc/sysconfig/network-scripts/ifcfg-*; do echo -e ‘\n#’ $i; cat
    $i; done

    # /etc/sysconfig/network-scripts/ifcfg-br0

    # /etc/sysconfig/network-scripts/ifcfg-eno1
    #TYPE=Ethernet NAME=eno1

  • As a desperate attempt, I disabled IPv6
    fcd8ee]. The VMs start properly, but now I am with out IPv6. So this is a workaround for the interim.

    I should have been more clear, I made NO customizations except as pasted previously. What ever the minimal install uses is what I have.

    I really do not know enough about systemd, but I think this might answer your question.

    # systemctl | grep -i net sys-devices-pci0000:00-0000:00:09.0-0000:01:00.0-0000:02:01.0-0000:03:00.0-0

  • 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 “” with
    “”, 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 ( 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.

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