Yaniv,

I have one of my developers assisting me and we are continuing to run into
issues. This is a note from him:

Hi, I'm trying to add a host to ovirt, but I'm running into package
dependency problems. I have existing hosts that are working and integrated
properly, and inspecting those, I am able to match the packages between the
new host and the existing, but when I then try to add the new host to
ovirt, it fails on reinstall because it's trying to install packages that
are later versions. does the installation run list from ovirt-release35
002-1 have unspecified versions? The working hosts use libvirt-1.1.1-29,
and vdsm-4.16.7, but it's trying to install vdsm-4.16.30, which requires a
higher version of libvirt, at which point, the installation fails. is there
some way I can specify which package versions the ovirt install procedure
uses? or better yet, skip the package management step entirely?
