Hi guys.
I have a domain definition with this:
...
<qemu:commandline>
<qemu:arg value='-fw_cfg'/>
<qemu:arg
value='name=opt/com.coreos/config,file=/00-VMs/oshift1node.ign'/>
</qemu:commandline>
</domain>
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):
https://libvirt.org/formatdomain.html#smbios-system-information
<sysinfo type='fwcfg'>
<entry name='opt/com.example/name'>example value</entry>
<entry name='opt/com.coreos/config' file='/tmp/provision.ign'/>
</sysinfo>

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
