Hi,
I was testing the hosted-engine in 3.4 and ran into some troubles, so 
I'm going to share the results to get some help (or ideas how to fix 
those problems)

Minor:
1. You need to have some MAC address with static ip and FQDN, otherwise 
you have to change /etc/hosts at least for the first part of the setup

- I think the setup wizard should be improved to do this workaround 
automatically

2. When the VM install is complete I would expect the setup wizard to 
install the engine to the VM automatically - which at least in my case - 
doesn't happen

- I found a mallformed fedora-virt-prerelease.repoo file on the 
installed vm, which might be the cause: 
https://bugzilla.redhat.com/show_bug.cgi?id=1075963

Major:
1. once I managed to install the engine to the vm it tried to add the 
host it was running on to the engine and it failed with a message "Host 
compatibility version doesn't match the cluster compatibility version", 
and then it marked the host as non operational which killed the vm with 
the engine, so the engine actually committed suicide...

- the host and the engine were installed from the same repo, so I guess 
the incompatibility was caused by the CPU family, and even if I made the 
mistake I think the engine should be a bit more clever and not kill itself
