Throughout the build there are calls like git clone http://github.com, git

​What exactly are you​ are you trying to download from? Do you have any

Is anyone else having problems with downloads? We've had a few reports but
we hadn't have time to figure out what's causing it. The hypervisor seems
to show good speeds while the guests are slow. That makes me wonder if the
virtio-net layer isn't working on those VMs.
