##### SUMMARY
<!--- Explain the problem briefly below -->
The setup module tries to detect is RHEV is running and set `virtualization_type` to "RHEV" if so, but it checks for a process running named "vdsm". The process is actually named "vdsmd", at least in newer versions of RHEV. (I don't recall if it used to be named differently.)

This is a clear failing of `lib/ansible/module_utils/facts/virtual/linux.py` where it only checks for processes named "vdsm" instead of "vdsmd". This problem continues to exist in the devel branch.

Here's useful information from my running RHEV system:

```
# grep vdsm /proc/*/comm
/proc/4772/comm:supervdsmd
/proc/5519/comm:vdsmd
```
