vdsm-devel at fedorahosted.org may be a better place to ask vdsm-specific
questions.

Could you log into the non-operational host as root, and stop the vdsm
service.

Then become the vdsm user with

    su -s /bin/bash - vdsm

and run /usr/share/vdsm/vdsm manually. Do you see anything in
particular?
