I'm still working on my reply to laszlo's earlier mail, but one thing I want
to point out is that virt-install is still an option, and in fact much easier
to describe in documentation, etc.
The ideal split IMO is:
- virt-manager only provides an option for using the recommended config using
distro packages, and disables the option with a useful error if no distro
packages available
- everything else we document with virt-install/virt-xml
- editing qemu.conf shouldn't be part of any standard recommendation and only
reserved for people who really know what they are doing
I like the idea of a .d directory, and I'm sure libvirt would find other uses
for sharing .d directory infrastructure, but yeah it'll definitely be a fair
chunk of work to support it, document a public ini format, then expose that
over libvirt APIs (since virt-manager can't depend on reading it directly
since we have to handle the remote machine case).
I think for now it's fine to add a libvirt build option like ./configure
--distro-nvram-default $FD:$VARS or similar
