Hi buddy,I encoutered a issue: Enviroment:ovirt 3.5,node2+node3+engine,node2 and node3 are in the same cluster. node2:64GB memory node3:64GB memory If I try to start 25 VMs on node2,node2's Memory usage is almost up to 80% But if I start 25 VMs on node3,node3's Memory usage is normal,about 70% VMs are all the same. And I checked out "Hosts>General". on node2: Physical Memory:64301 MB total, 49512 MB used, 14789 MB free Swap Size:28567 MB total, -858090 MB used, 886657 MB free Shared Memory:57% Max free Memory for scheduling new VMs:24191 MB Memory Page Sharing:Active on node3: Physical Memory:64301 MB total, 37938 MB used, 26363 MB free Swap Size:28567 MB total, 161 MB used, 28406 MB free Shared Memory:98% Max free Memory for scheduling new VMs:24191 MB Memory Page Sharing:Active Best regard
