[libvirt] how did libvirt manage Virtual Network?
Working at the network management, I am a bit confused about the
VLAN model in libvirt.
in the xml definition, there is a section as following:
<devices>
<interface type='network'>
<source network='default'/>
</interface>
...
<interface type='network'>
<source network='default' portgroup='engineering'/>
<target dev='vnet7'/>
<mac address="00:11:22:33:44:55"/>
<virtualport type='802.1Qbg'>
<parameters managerid='11' typeid='1193047'
typeidversion='2'
instanceid='09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f'/>
</virtualport>
</interface>
</devices>
What is the really meaning of its related parameters of
"virtualport"? I want to discover informations such as VLAN id,
the switch type( software switch or hardware switch), connecting
relationship, but from the xml I can only found "managerid". I am not
sure how to map these xml information to those I needed, could I
consider managerid as VLAN id, and a portgroup as a specified VLAN group?
By the way to use virtualport, what components should I install on
Linux?
