Upstream commit 598881800825 ("vsock: Fix blocking ops call in
prepare_to_wait") was subsequently reverted in 6f57e56a1527, which said:
The commit reverted with this patch caused us to potentially miss wakeups.
Since the condition is not checked between the prepare_to_wait and the
schedule(), if a wakeup happens after the condition is checked but before
the sleep happens, we will miss it. ( A description of the problem can be
found here: http://www.makelinux.net/ldd3/chp-6-sect-2 ).
The underlying issue has been fixed instead with f7f9b5e7f8ec ("AF_VSOCK:
Shrink the area influenced by prepare_to_wait").

Base repo for Moby, codename for the Docker Linux distro
Initial requirements are being driven by the very minimal goal of replacing boot2docker for the new Mac app.
However these requirements are fairly small and the scope is intended to be much broader.
Simple build instructions: use make to build. make xhyve will boot it up on a Mac; unless you run with sudo you will not get any networking.
make qemu will boot up in qemu in a container.
You can build for arm, some parts still under development, make clean first, then make qemu-arm will run in qemu.
