I'm trying to shrink the disk my Windows 10 VM is installed on from 180G down to 100G. I've already shrunk the disk in Disk Management so it shows 97.6GB capacity in explorer (with 83.1 GB used). While the VM is running it shows 82GB allocation in Unraid's VM interface, but when I shut down the VM it jumps to 159GB. Why is this happening? Is it still safe to run "qemu-img resize vdisk1.img 100G" on this vdisk?
Update: I noticed the same thing appears to happen in Spaceinvader One's video and he was able to resize it without issue. Still curious why the reported allocation is wrong.
