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
