I'm running Proxmox on an Intel Core i9-12900H with 32GB RAM and 1TB NMVe. I have configured 2 Windows 10 Pro X64 VMs to each use 8 cores and 15GB of RAM. The Boot disk was configured at 100GB (Default). I have noticed that as time goes on the "Local" HD will fill up to 100% if I let it go long enough. Screen shot of what it looks like after a while.

Here is the VM configuration:

Here are the options:

Note I also directly edit the configuration file and add "args: --snapshot" since the machines should be restarting after each CI build that they perform.

I have been reading other threads, but nothing is really sticking out as matching my configuration.

ncdu / output:

Output from the storage.cfg file:
```
root@pm2:/etc/pve# more storage.cfg
dir: local
path /var/lib/vz
content backup,vztmpl,iso

lvmthin: local-lvm
thinpool data
vgname pve
content rootdir,images

```

More output to maybe help diagnose?
```

I am new to Proxmox. The interesting part is that I have another one of the physical machines that run a pair of Linux VMs that do _not_ have this issue. Not sure if there was something I needed to setup specifically for Windows 10 Pro VMs? I just used a one of the tutorials from YouTube.

I do have the machines in an HA group so they get restarted after they shutdown. They will shutdown when they complete a CI build.

Any help would be much appreciated.
