Hello.
I have a strange error with one of my VMs. If i use dumpxml to save a VM
description the source part of the network part is missing. This prevents
redifining the machine from the dumped xml file:
This is how it looks before dumpxml:
<interface type='bridge'>
<mac address='52:54:00:34:a1:56'/>
<source bridge='br406'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03'
function='0x0'/>
</interface>
And afterwards:
<interface type='bridge'>
<mac address='52:54:00:34:a1:56'/>
<target dev='vnet6'/>
<model type='virtio'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03'
function='0x0'/>
</interface>
Someone has an idea whats causing this? Is there a special option maybe?
1) what is the libvirt version?
2) are you using "virsh dumpxml --inactive"?
The source should anyway be there when you do virsh dumpxml with or
without --inactive, but the proper way to get the config of a domain
that can be fed back into the domain is by using --inactive (otherwise
you get the current status of the interface, which may have some
differences).
(I'm interested to learn the libvirt version because when I look at the
virsh dumpxml of an <interface type='bridge'> on my system running
current upstream libvirt, I *do* see the <source> element. Given the
version you're running, I can possibly take a look at that vintage of
source to see if there was a bug in that version)
