ODA Memory Usage with KVMs
Hi
I have a ODA X8-2M with 19.24.0.0.0.
The ODA has 376GB of RAM. There are 2 KVMs running. One with 96GB RAM, the other with 72GB RAM.
root@oda01 [~] # odacli describe-vm -n kvm01 | grep Memory
Memory: 96.00 GB 96.00 GB
Max Memory: 96.00 GB 96.00 GB
root@oda01 [~] # odacli describe-vm -n kvm02 | grep Memory
Memory: 72.00 GB 72.00 GB
Max Memory: 72.00 GB 72.00 GB
root@oda01 [~] # free -h
total used free shared buff/cache available
Mem: 375Gi 365Gi 3.8Gi 42Mi 6.4Gi 3.2Gi
Swap: 33Gi 6.7Gi 27Gi
I noticed that the ODA itself uses more or less 50GB of memory. No clue why, but it does. If I summarize all this, and check the difference (376-96-72-50) there is 158 GB of RAM left. But in reality it is not.
