[Pkg-libvirt-maintainers] Bug#910857: VM configurated with spice not starting at boot

Thu May 9 12:37:54 BST 2019

  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...

  Regards,
    Vincent
