We have XenServer 7 installed on an HP Proliant DL360 Gen9 server, running 4 VMs. It has a total of 16GB.
Below is a brief info about the allocated memory for each one of the 4 VMs:
CentOS 7 test machine: 1GB RAM;
Windows 2012 R2 Server 1: 4GB RAM;
Windows 2012 R2 Server 2: 1GB RAM:
PF Sense Firewall: 1GB RAM.
However, on XenCenter, I get constant alerts regarding control domain/hypervisor memory usage, which say: ''The memory required by the control domain on server 'example' is 106.8% of its allocated memory. Occasional performance degradation can be expected when memory swapping is forced to happen''.
The CPU model is Intel Xeon CPU E5-2609 v3 @ 1.90GHz; Speed: 1897 MHz.
Is there any possible issue? Any best practice/tips to follow?
Thanks in advance
