Hi,
It worked fine on Linus tree commit:
7bb0338 Merge tag 'rodata-v4.11-rc1' of git://git.kernel.org/pub/scm/..
failed to start 2nd domain on this commit:
37c8596 Merge tag 'tty-4.11-rc1' of git://git.kernel.org/pub/scm/..
(this commit probably is not the first bad, i didn't do the bisecting)

The error message says that the spice remote desktop cannot listen on
-spice port=5900,addr=127.0.0.1.
Did you hardcode port 5900 in the domain XML? That could explain why
the second guest fails to launch - you need to use unique port numbers
or let libvirt automatically assign them. Check the domain XML:
<graphics type='spice' port='-1' tlsPort='-1' autoport='yes'>
Another possibility is that a process running on the host is already
using port 5900. Perhaps a guest or VNC server that was launched
outside of libvirt? You can check this with:
netstat -alpn | grep 5900

It looks like:
<graphics type='spice' autoport='yes'>
<listen type='address'/>
<image compression='off'/>
</graphics>

Please check that 11065/qemu-kvm was launched by the same libvirtd and
its domain XML also uses autoport='yes'.
I have CCed the libvirt mailing list because they may be able to explain
why there is a collision on TCP port 5900.

There was a bug in the code. There could be a race between startup of
two VMs:
