[Users] Adding Host

[Doron Fediuck]

Basically the bootstrap process is making sure the relevant RPM files
are installed, and conflicting packages are either removed or causes
failure. There are some conflicts that are not in RPM level, which
bootstrap knows how to handle. These will not be handled in the path
you're taking. Similar issues you should expect is bios virt flags
and kernel / OS validations bootstrap is doing.

Furthermore, bootstrap is auto-generating a vdsm configuration, as well
as other things such as networking (which you stumbled upon), time-sync,
key & certificate generation signed by the engine-core, along with
setting up a core-dump folder and probably some other things which I
forgot.

So as you can understand bootstrap is handling many issues, and manual
installation, although possible, will not b e a simple one. If you're
heading this way I suggest you read the vdsm_bootstrap, vdsm_bootstrap_complete,
deployUtil and vds_installer python scripts. All should be available
on your engine-core machine.

From this point of view, we concentrate on VDSM, while kvm is simply a kernel module which should be loaded. Anything beyond will probably cause manual intervention as you just had.
