Hi,
I have a question about interface script (e.g., qemu-ifup) for qemu/kvm.
qemu/kvm is dropped its all capabilities by libcap-ng before executed.
So the script that is executed by qemu/kvm will fail if it executes
privileged operations which are usual jobs of it.
It means we cannot use <script> anymore? or I'm missing something?
That is correct.
I think executing the script in libvirtd after creating a tap and
before
dropping capabilities would be a solution for that issue. Am I wrong?
If we want to keep the 'script' capability, then that is pretty much the
only option I see. Personally though I'd rather people never used the
script capability because its an opaque blackbox doing who knows what
