The parameter "xen.check.hvm" was supposed to control if the host should be hvm 
enabled or not.
Currently, since it is not set in the db implies that only hvm enabled 
xenserver host can be added to the cloud.
HVM mode is required for windows VM.

It is right to enforce the hvm mode for the cloud as otherwise it will not be 
able to support the full cloud functionality.
