Description of problem:
User can set the proxy selection via API, GUI and rhevm-config
the relevant parameter is FenceProxyDefaultPreferences.
FenceProxyDefaultPreferences can accept parameters like:
A validation pattern of the IP/FQDN and check that the host is legal and its
status is UP should be added.
(if not , we will ignore that and continue to next option)
This issue is derived from what wasn't implemented in 3.2 https://bugzilla.redhat.com/show_bug.cgi?id=747305
IMHO this is a RFE not a bug
Closing old bugs. If this issue is still relevant/important in current version, please re-open the bug.
