Verify it with build libvirt-1.2.15-2.el7.x86_64
Steps:
1. edit guest with XML
# virsh edit vm2
...
<graphics type='spice' autoport='yes' keymap='en-us'>
<listen type='network' network='default'/>
</graphics>
...
2. dumpxml and domdisplay
# virsh dumpxml vm1
...
<graphics type='spice' port='5900' autoport='yes' listen='192.168.122.1' keymap='en-us'>
<listen type='network' address='192.168.122.1' network='default'/>
</graphics>
...
# virsh domdisplay vm1
spice://192.168.122.1:5900
3. connect guest with remote-viewer and virt-viewer on local host success
# remote-viewer spice://192.168.122.1:5900
# virt-viewer vm1
4. set with vnc, check domdisplay
...
<graphics type='vnc' port='-1' autoport='yes' keymap='en-us'>
<listen type='network' network='default'/>
</graphics>
...
# virsh domdisplay vm1
vnc://192.168.122.1:0
5. use virt-viewer or remote-viewer vnc://192.168.122.1:5900 connect guest success
6. try with another bridge network br1
# virsh net-dumpxml br1
<network>
<name>br1</name>
<uuid>8a2e947d-c1d5-4695-2881-5f877ced63e0</uuid>
<forward mode='route'/>
<bridge name='br1' stp='on' delay='0'/>
<mac address='52:54:00:ad:88:b2'/>
<ip address='10.0.0.1' netmask='255.255.255.0'>
<dhcp>
<range start='10.0.0.2' end='10.0.0.254'/>
</dhcp>
</ip>
</network>
7. dumpxml and domdispaly guest
# virsh dumpxml vm1
...
<graphics type='vnc' port='5900' autoport='yes' listen='10.0.0.1' keymap='en-us'>
<listen type='network' address='10.0.0.1' network='br1'/>
</graphics>
...
# virsh domdisplay vm1
vnc://10.0.0.1:0
8. connect with remote-viewer or virt-viewer to guest success
# remote-viewer vnc://10.0.0.1:5900
9. try with direct network
# virsh net-dumpxml bridge-net
<network>
<name>bridge-net</name>
<uuid>d4282a3c-029a-a48a-9d04-e340f9ebc053</uuid>
<forward dev='eno1' mode='bridge'>
<interface dev='eno1'/>
</forward>
</network>
# virsh domdisplay vm1
spice://10.66.7.206:5900
10. remote-viewer also works well
# remote-viewer spice://10.66.7.206:5900
11. prepare a remote guest on host with libvirt build libvirt-1.2.8-16.el7.x86_64
configure the remote guest with network bridge
# virsh dumpxml rh7
...
<graphics type='spice' port='5900' autoport='yes' keymap='en-us'>
<listen type='network' address='192.168.122.1' network='default'/>
</graphics>
...
12. connect remote guest on local host with libvirt build libvirt-1.2.15-2.el7.x86_64
check domdisplay show remote host IP is right
# virsh -c qemu+ssh://$remotehostIP/system
root@$remotehostIP's password:
