You also loose the benefit of libvirt's API abstraction. If QEMU guest
agent is replaced by something different in future, a formal API in
libvirt insulates the apps from that difference, both within context of
a single hypervisor, and cross hypervisor.
Yes, basically my question was whether it's worth doing individual APIs
for all of those things especially since we usually don't try to deal
with what's running inside the VM. I'm not 100% persuaded, but we have
plenty prior art and the insulation argument makes sense (as long as the
replacement has the capabilities).
If we do want to keep adding the APIs I'm fine with the patches as-is,
as any other solution would be extremely gross.
Obviously v2 is required due to the security problems.
