Re: [Engine-devel] hosted engine in 3.4
Hi,

I believe you were there when we were discussing this with pstehlik :)
Btw in this case you have to change /etc/hosts on all hosts and inside the
engine VM.

I also proposed kickstart based setup to Sandro. You would give a repo to setup
and it would download the kernel/initrd from it [1] and create a kickstart with
the right root password, engine setup and so on..

Check your VDSM version. Especially the content of /usr/share/vdsm/dsaversion.py
file. There are couple of lists specifying the cluster and engine versions that
the VDSM supports.
If you use 3.4 engine it needs 3.4 VDSM as well.. and the prerelease repo is not
enabled by default.

I think it is the VDSM that does the actual killing :)
But overall I agree, the setup is too fragile and I encountered all of the issues
when installing hosted engine for the first time too.
