Hi, I also have this problem. With machines configured with spice, I can find in the log (/var/log/libvirt/qemu/<vm>.log at boot time:
[...] char device redirected to /dev/pts/9 (label charserial0) ((null):6261): Spice-Warning **: reds.c:2489:reds_init_socket: getaddrinfo(127.0.0.1,5900): Address family for hostname not supported 2019-05-08T13:15:34.165013Z qemu-system-x86_64: failed to initialize spice server 2019-05-08 13:15:34.288+0000: shutting down, reason=failed [the whole log is at the end of this message] I've no problem with VMs not using spice but all of VMs with spice fail to start at boot time. If I start them after (generally with virt-manager but sometimes with virsh), it works perfectly. It is a long outstanding bug. I tried to track it down when systemd was not there yet, so I was able to start the services one by one. It occurred that the problem disappeared if VMs was started *after* the network. I think this is linked to the fact that the code is using getaddrinfo with AI_ADDRCONFIG. See https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1492621 and https://bugzilla.redhat.com/show_bug.cgi?id=721350 for more info. In my case, I cannot just start the network before the VMs as one of my VMs is my dhcp server... So I remove spice from the config of VMs that must start early. However, I think there is a problem to mandate that a not-localhost address exists on the system to allow one to start a VM. Using VNC instead of Spice does not lead to the same problem. And, if it is absolutely required, the error message could be more informative at least...
