Evening, I just deleted the virtualbox 6.1 from my system (Linux 20.04), I was hoping the partitioned hard drive would go back to its normal state after removing the virtualbox, now I don't have enough space on to configure the newly installed virt-manager (I had allocated about 32GB to the VM) how can I recover the "lost" storage space? please help... (the disk partitioning is showing: part 1- 600MB & part 2: 61GB of 64GB)
Your disk does not seem to be partitioned to 32+32. You probably configured VM to use an image file, not a dedicated partition. After you removed the VM itself, it's data (including 32Gb image) are still there. You can probably
sudo apt purge virtualbox
sudo apt remove virtualbox
this will probably remove the VM disk image. Or you can remove it manually, but I can't tell for sure where it is.
