[Pkg-ganeti-devel] automatic failover with ganeti.

[BRULÉ Yann]

Hi !

I try to download ganeti-watcher but I don't know where to find it. Someone could tell me where I can find it and how to configure it to do an automatic failover?

Thank you !

Have a good day.

The testcases which are in the git are only for ganeti base classes.
I patched an executable script, which doesn't have any test script :)

Cheers,
