Hi Amos,
I'm a libvirt QE, and I can not understand the setting on libvirt.org for
rng device.
Could you please help to explain a little?
(The xml in https://libvirt.org/formatdomain.html#elementsRng)
<devices>
<rng model='virtio'>
<rate period="2000" bytes="1234"/>
<backend model='random'>/dev/random</backend>
<!-- OR -->
<backend model='egd' type='udp'>
*<source mode='bind' service='1234'/>*
* <source mode='connect' host='1.2.3.4'
service='1234'/>*
</backend>
</rng>
</devices>
How did it work with source mode='bind' and source mode='connect'
together?
It doesn't. That's just an example that you can have two types of
backend. Either the backend connects somewhere (mode='connect'), or
expect somebody to connect (mode='bind'). Just try to define domain with
that RNG, dump the XML back and see what got applied.
