I am not a proxmox expert so I would really appreciate if someone could shed some light on this "enigme" I am facing.
A Client our product running on a Proxmox installation
Now the (not so) funny thing is that the machine has swapped even if it has never allocated all the ram, and in particular it swaps out our virtual machine even if it has not even allocated all of the alotted ram.

Would any one be able to explain why the virtual machine 116 has been swapped even though there are in the order of 26g ram free.
Name: VMID: 116
Guest Type: Other
Cluster Node: proxmox (192.168.10.3)
Memory (MB): 57344
CPU Sockets: 2
Cores/Socket: 3
Start at boot: Yes
Has it got to do with the fact that the machine has been allowed to use 3 (out of 4) processors on each of 2 sockets?
Any information welcome
Thanks in advance
