Hi,
I'm trying to give libvirt knowlegde of a VLAN interface that is
configured by a different means and not by libvirt. To figure out the
syntax, I created a VLAN interface through virt-manager and dumped out
the XML:
<interface type='vlan' name='ens3.180'>
<protocol family='ipv6'>
<ip address='2a01:4f8:150:436c::55:100' prefix='64'/>
<ip address='fe80::5054:ff:fe30:e0d1' prefix='64'/>
</protocol>
<link speed='4294967295' state='up'/>
<vlan tag='180'>
<interface name='ens3'/>
</vlan>
</interface>
I then removed the Interface in virt-manager and tried to have libvirt
read back its own XML.
[12/784]mh@testsid85:~ $ virsh iface-dumpxml ens3.180 > ens3.180.xml
[13/785]mh@testsid85:~ $ virsh iface-define ens3.180.xml
error: Failed to define interface from ens3.180.xml
error: XML error: could not get interface XML description: XML invalid - Expecting an
element start, got nothing
What is going on here? How do I define a VLAN interface via XML?
This is weird. However, I'm unable to reproduce with the latest libvirt.
What's your version? Have you tried the latest one?
