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
