Description Arik 2020-06-18 14:44:43 UTC 
This bug is about the second part of bz 1806339 - showing the total number of huge pages on the host.
Comment 2 Qin Yuan 2022-04-19 13:11:00 UTC 
Verified with ovirt-engine-4.5.0.2-0.7.el8ev.noarch

Before VMs starting on host:
Huge Pages (size: free/total):  2048: 1024/1024, 1048576: 4/4

Start VM1(system memory 1024) with HugePages 2048, VM2(system memory 1024) with Hugepages 1048576,  VM3(system memory 3072) with HugePages 1048576:
Huge Pages (size: free/total):  2048: 512/1024, 1048576: 0/4


Check free/total huge pages in host statistics via API:
