Greetings Laine,
you are correct, this prints are from a non libvirt network config, the following are, they show the same issue I've deleted the rest of the mail it isn't relevant:
there are two vms:
Id Name State
----------------------------------------------------
1 router running
5 TvHeadend_server running
and the following network:
Name State Autostart Persistent
----------------------------------------------------------
default active yes yes
Name: default
UUID: 735c1a37-5af8-4cad-a620-6f55046060dd
Active: yes
Persistent: yes
Autostart: yes
Bridge: virtsw0
router's virtual interfaces in xml file:
<interface type='ethernet'>
<mac address='52:54:00:8b:66:c1'/>
<target dev='vnet0'/>
<model type='virtio'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x08' slot='0x00' function='0x0'/>
</interface>
<interface type='bridge'>
<mac address='52:54:00:a7:79:6b'/>
<source bridge='virtsw0'/>
<target dev='vnet1'/>
<model type='virtio'/>
<alias name='net1'/>
<address type='pci' domain='0x0000' bus='0x0a' slot='0x00' function='0x0'/>
</interface>
TvHeadend_server's interfaces in xml file:
<interface type='bridge'>
<mac address='52:54:00:54:78:be'/>
<source bridge='virtsw0'/>
<target dev='vnet2'/>
<model type='virtio'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
</interface>
here is the output of ifconfig -a from within the router vm:
