Hi guys.

I have a domain definition with this:
     <qemu:arg value='-fw_cfg'/>

at the bottom of xml.
'virsh' creates domain a okey but in VM I do not see ignition happened -
it's fedora coreos - and when I dumpxml running domain, then indeed
those bits, show above, are not there.

I'd grateful for any/all thoughts shared on - what is not/happening there.
Is there something else which is a prerequisite to 'qemu:commandline'
but if yes and I'm missing those, why would not then 'virsh' and/or
'virtqemud' say something?

many thanks, L.
No need for using <qemu:commandline/> as this is well configurable via
domain XML (for ~3 years):

<sysinfo type='fwcfg'>
   <entry name='opt/com.example/name'>example value</entry>
   <entry name='opt/com.coreos/config' file='/tmp/provision.ign'/>


this gets more neat every minute one learns more of libvirt.
So, I'd take this chance and ask - can we pass paramas to the kernel, like APPEND? I'm thinking.. would be great co have net ifaces configured that(some) way.

many thanks, L
