Hi,
no idea if/how this is applicable to the VirtualBox / Vagrant -based
build setup, but in my own libvirt/kvm one, I've halved the time
needed to copy the build products from the build VM back to the host
system, by switching from scp (-o Cipher=none) to a good old "cp" to
a virtio/9p virtfs mount:

Cheers,
