Hope that helps. Best Regards, Roman > > [1] https://gerrit.ovirt.org/#/q/status:open+project:ovirt-vdsmfake+branch:ma... [2] https://gerrit.ovirt.org/#/c/53570/ [3] https://gerrit.ovirt.org/#/c/53570/2/README I could finally make fakevdsm work with your changes. Maybe I'm missing something but this works if the engine and the fake host are run on the same server - when I tried to run the fake host on a different host I wasn't seeing any responses from the host (the firewall was vanilla clean). In any case, I'm ok with both running on the same machine.

Will this be merged into master?

Thanks.
