Still fais with 3.16.0-30.40

CC'ing Luis Henriques since he is the one who uploaded the original broken release.

We don't even remotely support running systemd as init on 14.10, so I'm not entirely sure what to do with this bug report.

Fair point but why do you think this is a systemd problem?

I don't necessarily think it's a systemd issue, but without debugging info from running the daemon by hand, it's hard to tell what's happening. It could just be that it's running in a way systemd doesn't expect (perhaps backgrounding, when it expects it to stay in the foreground?)

Ok your last comment put me in the right direction.

Both /lib/systemd/system/hv-vss-daemon.service and /lib/systemd/system/hv-kvp-daemon.service has

Type=forking

but they don't fork hence systemd kills them after some time. Removing this field fixes the problem. So, can we get an update with that fixed? :)

/lib/systemd/system/hv-fcopy-daemon.service has the same problem btw.

@Ismail -- could you test the kernels at below and let me know that they work for you under systemd? Kernels are at the URL below:

Please report any testing back here. Thanks.

Looks good:
