Hey, Is that the case with you too?
I have Home Assistant installed in a VM. There I assigned it 8 GB of RAM. According to Proxmox, they are almost completely used.
However, in HomeAssistant, I only see 2.2 GB / 8 GB.
How can that be and how can I change that?

Check free -m in HAOS' shell (type login first). PVE counts the buffers and caches too. Also make sure you have ballooning and guest agent enabled.

Checks out. Used + Buffer/Cache and you come near PVE's value.
5349 + 1940 = 7289MiB. 7289MiB = 7.12GiB

Ahh okay, that's more or less correct.
but why is it added together in this case but not in my Windows VM?
Ballooning & guest agent are enabled

Windows, or rather its driver, probably reports it differently. For windows you also need the drivers

Yeah thats right. Something with virtIO
so is the behavior normal? So is it like that for everyone?

The linux behavior is normal, see link. My windows VM's used memory is very close to the task manager's.
