System Alert: Low Available Memory in cluster

[Leandro Ramos]

Hi :)

I'm getting this error: "System Alert: Low Available Memory in cluster 
Cluster01 pod Pod01 of availability zone Zone01"

I don't know how much RAM and CPU I have to allocate to KVM Host. I have 
a dedicated server with the following config:

- CPU - 12c/24t - 3.7GHz/4.8GHz
- RAM - 64GB
- Disks: SSD 500GB + HDD 6TB
- Bandwidth - Public 1Gbit/s and Private 2Gbit/s

Both Management Server and KVM Host are VMs inside this dedicated server.

KVM Host config:

- 4 vCPU (host-passthrough)
- RAM 4GB
- Disk 50GB

Management Server config:

- 2 vCPU
- RAM 4GB
- Disk 50GB + 6TB (it's also my storage server)


I really don't know how to allocate more resources to the cluster. I 
need your help.

I will paste the error here:
