This sounds like a problem with persistent vs non-persistent tap interfaces. This functionality is unfortunately very non-portable (MacOS X, FreeBSD and Linux) all have different behaviour. The functionality did change between version 2.2.0 and 2.1.0 to support persistent interfaces: https://github.com/mirage/mirage-net-unix/releases <https://github.com/mirage/mirage-net-unix/releases>
So I wonder if something needs to be done to keep it around on your particular setup. (This isn't helped by me now using mirage-net-macosx for most of my day-to-day dev, which uses a completely different codepath as tuntap no longer works usefully on OSX as of Yosemite). -anil > On 30 Apr 2015, at 23:49, Robert Ream <[email protected]> wrote: > > An update: I just cloned the mirage-net-unix repo and ran the tests.
