  centos   1   6   0 wz--n- 24.51g 3.75g



Expected results:
In RHEV-H 7.2, the VG name show as "HostVG", so I suggest to change ngn 4.0 VG name to "HostVG".

Comment 1 Fabian Deutsch 2016-08-29 15:58:07 UTC 
The name is not important, it's the label which identifies the relevant VG.
Comment 2 Ying Cui 2016-08-30 06:43:42 UTC 
Tested on last redhat-release-virtualization-host-4.0-2.el7, there display correct VG name as rhvh, so the original reporter's issue is gone.
