I've seen references to at least a balloon driver as well as to a balloon service.

Usually, a balloon device does appear on systems. I don't recall if that is done when the VM is specified with variable memory instead of fixed. In any case, the balloon driver from the virtio tools seems to be ok.

Furthermore, when the VM is running it is responding to balloon command requests from the pve console. At some point though there was reference to a balloon service. For example, see https://pve.proxmox.com/wiki/Dynamic_Memory_Management#Enable_Auto-Ballooning_on_Windows_2012.2FWin8

My questions are:
1) Are these instructions still valid on the wiki? That is, the service is needed too?

2) What does the service do that necessitates its installation along the balloon driver?

Thanks in advance for any info provided.
 
NVM, yes the service is needed; it provides info on what the really used memory by the VM is...
