When I run VM that I have allocated 12GB of RAM with Windows, 12GB of RAM is consumed on the main dedicated server. (Even if 1GB is used in Windows.) but when I run the same server as Linux, it affects how much RAM is consumed in Linux. VirtIO drivers are installed in Windows and they work without any problems. Why is there such a problem for Windows? How can I solve it?
Windows high RAM usage
- Thread starter Talha
- Start date
For a more accurate reading, the balloon driver needs to be installed (ballooning does not need to be enabled but the virtual device must be present and the driver installed), but on some operating systems the balloon driver does not report the memory usage (like FreeBSD).
When using PCI(e) passthrough, all VM memory must be pinned into actual host memory, because of the possibility of DMA at any time initiated by the PCI(e) device(s).
(There are many post on this forum about why the memory usage inside a VM is always different from the usage reported by Proxmox, if you can find them.)

We need at least one wiki article about it. Every month, an old questions is reasked and I don't have a list of my previous answers, I should create one.
One Google search away, I found this, which also links to the article about dynamic memory management.
